alphabetical order.
In addition to the command listings, the Command
■ Using This Reference
■ Typographical Conventions
Reference covers several topics in the appendixes:
command aliases, system variables, dimension
variables, utilities, standard libraries, graphical
database objects, and Unicode fonts.
The index for the Command Reference is at the end of
Volume II.
1
Using AutoCAD Documentation
In addition to this Command Reference, several other resources are available to
help you learn and use AutoCAD. The complete documentation set for
AutoCAD is online. You can access it from the Help menu.
Note For the latest documentation corrections and additions, refer to the
Readme file.
Using This Reference
The Command Reference provides detailed information on all commands,
command options, and system variables. The explanations reflect the default
AutoCAD system variable settings and the default prototype drawing. If you
change system variable settings, the prompts on your screen might differ
from what you see here. For example, the setting of the FILEDIA system variable governs whether you work in a dialog box or on the command line
when you use certain commands. See appendix B, “System Variables.”
Executing Commands
The process of executing a command begins by starting the command, using
one of several methods. For some commands, such as REGEN, no further
action is required. For other commands, you must respond by providing
additional information or actions in order to complete the command.
As you work with commands, note that right-clicking in the drawing area
either acts as ENTER or displays a shortcut menu. You can control this behavior in the Options dialog box or with the SHORTCUTMENU system variable.
Starting Commands
You can start a command by doing one of the following:
■
■
Select the command from a menu, toolbar, status bar, or shortcut menu.
Enter the command name or command alias at the Command prompt
and press ENTER or SPACEBAR .
For a list of the aliases that correspond to each command, see appendix A,
“Command Aliases.”

Introduction
In this Command Reference, near the beginning of each command description
is a command access section, listing the specific ways you can start that command. For example, following is the command access section for the PAN
command:
Standard toolbar:
View menu: Pan ➤ Realtime
Shortcut menu: With no objects selected, right-click in the drawing area,
and choose Pan.
Command line: pan (or 'pan for transparent use)
The availability of certain shortcut menus depends on the current setting of
the SHORTCUTMENU system variable. The instructions in the command
access sections assume that you have made the indicated menu available.
You can exit a command at any time by pressing ESC .
Using Transparent Commands
In many cases, you can start a command while using another command. The
command you start is called a transparent command. For example, to turn on
the grid while drawing a line, you can start the GRID command transparently
by preceding the command with an apostrophe. Two right angle brackets
(>>) precede prompts for transparent commands.
Command: line
Specify first point: 'grid
>>Specify grid spacing(X) or [ON/OFF/Snap/Aspect] <current>: on
Resuming LINE command
Specify first point:
In the Command Reference, the command access sections identify commands
that you can use transparently.
Suppressing Dialog Boxes
Many commands provide both command line and dialog box interfaces. In
most cases, when both a command line and dialog box interface are available, the command line version is preceded with a hyphen character. For
example, the command line version of GROUP is -GROUP.
You can also control the display of file dialog boxes through the FILEDIA
system variable. See appendix B, “System Variables.”

Responding to Prompts
If a command does not immediately execute, AutoCAD either displays a
dialog box or displays prompts on the command line requesting more
information. Command line prompts are structured as follows:
Command: commandname
Current settings: Setting1 Setting2 Setting3
Instructional text [Option1/oPtion2/opTion3/...] <default option or value>:
The optional current value line displays the current settings for the command or for system variables related to the command. The succeeding
prompts identify the type of input required to complete the command and,
when applicable, list the available options in straight brackets and a default
option or value in angle brackets. In some cases, AutoCAD determines
default options and values based on the option or value that you last specified, or based on the settings of certain system variables.
Typically, the first word of a prompt indicates the type of action you can take.
Most command line prompts begin with the word enter, select, or specify.
These words indicate how you can respond to the prompt.
Terminology in command line prompts
If the prompt starts with...
You can...
Select
Select objects on the screen using your pointing
device.
Enter
Enter text on the command line.
Specify
Use your pointing device or enter text on the
command line to select a point location on the
screen.
Selecting Options on the Command Line
To select one of the options contained within the straight brackets, you can
enter the entire option name or only the capitalized letters, and then press
ENTER or SPACEBAR . To select the default option enclosed in angle brackets
(<>), if available, press ENTER or SPACEBAR .

|
Introduction
You can also choose command options from a shortcut menu by rightclicking in the drawing area while the command is active. The options available on the command line appear in the shortcut menu. For information
about how to enable or disable this shortcut menu, see “Shortcut Menus” in
the User’s Guide.
Entering Data on the Command Line
Some prompts ask you to enter data, rather than (or as an alternative to)
choosing an option. To do so, enter the text on the command line and press
ENTER or SPACEBAR . However, be aware that when the command line prompt
requests an object name, SPACEBAR inserts a space on the command line
rather than acting as ENTER . This allows for the support of extended symbol
names.
Just as default command options are often provided, prompts may include
default values, enclosed in angle brackets (<>), when data is requested. For
example, the POLYGON command displays the following prompt, suggesting
4 as the number of sides for your polygon:
Command: polygon
Enter number of sides <4>:
To accept the default value, press ENTER or SPACEBAR .
Using Wild-Card Characters on the Command Line
When the prompt directions ask for a name list, such as a block name, variable name, named view, and so on, you can use wild-card characters to
specify names. See the table in “Filter and Sort the List of Layers” in the User’s
Guide.
Repeating Commands
If no command is active, you can repeat the previous command by pressing
ENTER or SPACEBAR or by right-clicking in the drawing area and choosing the
Repeat Command Name option from the shortcut menu.
Accessing Recently Used Commands
You can access the six most recently used commands from a shortcut menu
by right-clicking in the command window and choosing Recent Commands.
References to Other Sections
At the end of most command descriptions, you’ll find a section called “See
Also.” This section includes references to chapters in other AutoCAD guides
and other AutoCAD commands and system variables related to the current
command.

Introduction
***POP1
You can start a command by using one of the following methods:
■
■
Click the command name on a menu, toolbar, status bar, or shortcut
menu.
Enter the command name or command alias at the Command prompt
and press ENTER or SPACEBAR .
For a list of the aliases that correspond to each command, see “Command
Aliases.”
In this Command Reference, near the beginning of each command description
is a command access section that lists the specific ways you can start that
command.
3D
Creates three-dimensional polygon mesh objects
3D creates three-dimensional polygon mesh objects in common geometric
shapes, including boxes, cones, spheres, tori, wedges, and pyramids.
When you use 3D to construct polygon mesh objects, the resulting objects
are surfaces that can be hidden, shaded, or rendered.
Draw menu: Surfaces ➤ 3D Surfaces
Command line: 3d
Enter an option
[Box/Cone/DIsh/DOme/Mesh/Pyramid/Sphere/Torus/Wedge]:
Box
Creates a 3D box polygon mesh.
length
Specify corner point of box:
Specify length of box: Specify a distance
Specify width of box or [Cube]: Specify a distance or enter c
width
Width
Specifies the width of the box. Enter a distance or specify a point relative to
the corner point of the box.
height
Specify height of box: Specify a distance
Specify rotation angle of box about the Z axis or [Reference]: Specify an angle
or enter r

3D
|
7
Rotation Angle
Rotates the box about the first corner specified. If you
enter 0, the box remains orthogonal to the current X
and Y axes.
Reference
Aligns the box with other objects in the drawing or
relative to an angle you specify. The base point for the
rotation is the first corner of the box.
Specify the reference angle <0>: Specify a point, enter an
angle, or press ENTER
You can define a reference angle by specifying two
points or an angle from the X axis on the XY plane. For
example, you can rotate the box to align two specified
points on the box with a point on another object. After
defining a reference angle, specify a point for the
reference angle to align with. The box then rotates
around the first corner relative to the angle of rotation
specified for the reference angle.
If you enter 0 as a reference angle, the new angle alone
determines the rotation of the box.
Specify the new angle: Specify a point or enter an angle
To specify the new angle of rotation, specify a point
relative to the base point. The base point for the
rotation is the first corner of the box. The box rotates by
the angle between the reference angle and the new
angle. If you want to align the box with another object,
specify two points on the target object to define the
new angle of rotation for the box.
If the reference angle of rotation is 0, the box rotates the
angular distance entered relative to the first corner of
the box.
Cube
Creates a cube using the length for the width and height of the box.
Specify rotation angle of box about the Z axis or [Reference]: Specify an angle
or enter r
Rotation Angle

3D
Rotates the cube about the first corner of the box. If you
enter 0, the box remains orthogonal to the current X
and Y axes.
Reference
Aligns the box with other objects in the drawing or
relative to an angle you specify. The base point for the
rotation is the first corner of the box.
Specify the reference angle <0>: Specify a point, enter an
angle, or press ENTER
You can define a reference angle by specifying two
points or an angle from the X axis on the XY plane. For
example, you can rotate the box to align two specified
points on the box with a point on another object. After
defining a reference angle, specify a point for the
reference angle to align with. The box then rotates
around the first corner relative to the angle of rotation
specified for the reference angle.
If you enter 0 as a reference angle, the new angle alone
determines the rotation of the box.
Specify the new angle: Specify a point or enter an angle
To specify the new angle of rotation, specify a point
relative to the base point. The base point for the
rotation is the first corner of the box. The box rotates
the angular distance between the reference angle and
the new angle. If you want to align the box with
another object, specify two points on the target object
to define the new angle of rotation for the box.
If the reference angle of rotation is 0, the box rotates the
angular distance entered relative to the first corner
point of the box.
Cone
Creates a cone-shaped polygon mesh.
Specify center point for base of cone: Specify a point (1)
Specify radius for base of cone or [Diameter]: Specify a distance or enter d

You will stay in the 3DCONFIG command until you enter eXit or press ESC.
20
|
3DCONFIG
Adaptive Degradation
Specifies the display options to which the view can degrade to maintain the
speed of the view manipulation. For example, if a large drawing is currently
Gouraud shaded, you can select Wireframe to allow the drawing to degrade
to a wireframe representation of the view.
You can turn on one or more than one of the available options. If more than
one option is turned on, the display changes to the most detailed option first
and then degrades until it reaches the least detailed option.
Configure: Adaptive Degradation
Enter mode [ON/OFF] <ON>: Specify whether you want adaptive degradation
turned on or off
If Adaptive Degradation is turned on, you can specify the type. If no type is
specified, then no degradation will occur.
Current display options: Wireframe Bounding Box
Enter option [Flat shaded/Wireframe/Bounding box/Maintain speed fps/eXit]
<Flat shaded>: Specify the type of adaptive degradation you want to use
Configure: Flat shaded
Enter mode [ON/OFF] <OFF>: Specify whether you want flat-shaded display
turned on or off
Configure: Wireframe
Enter mode [ON/OFF] <OFF>: Specify whether you want wireframe display
turned on or off
Configure: Bounding box
Enter mode [ON/OFF] <OFF>: Specify whether you want bounding box display
turned on or off
Configure: Maintain speed fps
Enter speed <5>: Enter a value between 1 and 60 to adjust the frame rate
Flat Shaded
Specifies that the display can change to flat shaded.
Wireframe
Specifies that the display can change to wireframe. This
uses less of the system resources and allows the drawing
to move at a faster speed.
Bounding Box
Specifies that the display can change to a bounding
box. A box is displayed in place of each object in your
view. This choice requires the least amount of system
resources.
Maintain Speed
FPS
Specifies the display speed in frames per second. The
drawing degrades to maintain the specified speed.

Dynamic Tesselation
Sets the options that determine the smoothness of the objects in a drawing.
AutoCAD draws objects using many short lines (or triangles when drawing
spheres). These lines are called tessellation lines. Objects in your drawing
appear smoother when you use more tessellation lines.
Configure: Dynamic tessellation
Enter mode [ON/OFF] <ON>: Specify whether you want dynamic tessellation
turned on or off
If Dynamic Tessellation is turned on, you can specify the number of surface
tessellations, curve tessellations, or tessellations to cache.
Configure: Dynamic tessellation
Enter option [Surface tessellation/Curve tessellation/Tessellations to cache/eXit]
<Surface tessellations>: Specify the type of dynamic tessellation you want to use
Configure: Surface tessellation
Enter tolerance <88>: Enter a value between 0 and 100
Configure: Curve tessellation
Enter tolerance <88>: Enter a value between 0 and 100
Configure: Tessellations to cache
Enter number of tessellations to cache <3>: Enter a value between 1 and 10
Surface
Tessellation
Determines the amount of detail for surfaces in your
drawing. The lower numbers provide less detail; the
higher numbers provide more detail but use more
tessellation lines and more memory.
Curve
Tessellation
Determines the amount of detail for curves in your
drawing. The lower numbers provide less detail; the
higher numbers provide more detail but use more
tessellation lines and more memory.
Number of
Tessellations to
Cache
Configures your system according to memory and
performance requirements. A cache is a special memory
subsystem that stores frequently accessed information.
The 3D cache always stores at least one tessellation.
When the number of tessellations to cache is set to 1,
the tessellation for all viewports is the same and may
cause some objects in the drawing to be regenerated as
you zoom in and out.
22
|
3DCONFIG
Setting the number of tessellations to cache to 2 or
more is useful when you have more than one viewport
with different views. Increasing the number requires
more memory.
Render Options
Makes settings available for enhancing the display of lights, materials, textures, and transparency in 3D views. This includes objects in the 3D Orbit
view and objects shaded using the SHADEMODE command.
Configure: Render options
Enter mode [ON/OFF] <ON>: Specify whether you want to turn on render options
Configure: Render options
Enter option [Lights/Materials/eXit] <Lights>: Specify whether you want to
configure lights or materials
Configure: Lights
Enter mode [ON/OFF] <ON>: Specify whether you want lights turned on or off
Configure: Materials
Enter mode [ON/OFF] <ON>: Specify whether you want materials turned on or
off
If Render Options is turned on, you can specify if you want lights and materials turned on or off.
Lights
In 3D views, illuminates objects and attached materials
by lights that were defined with the LIGHT command. If
this option is not selected, or if the LIGHT command has
not been used for the drawing, then the default lighting
for 3D views is used.
Enable Materials
In 3D views, displays materials for objects that have
materials that were attached using the RMAT command.
If the object has no attached material, the default global
material is used. If this option is not selected, or if the
RMAT command has not been used in the drawing, then
no materials are displayed.
Configure: Textures
Enter mode [ON/OFF] <ON>: Specify whether you want textures turned on or off
Configure: Transparency
Enter mode [Low/Medium/High] <Low>: Select a transparency level
If Materials is turned on, you can also configure textures and transparency.
3DCONFIG
|
23
Enable Textures
In 3D views, shows textures attached to objects using
the RMAT and SETUV commands. Materials must also be
turned on for textures to be visible.
Transparency
Adjusts the transparency quality to improve image
quality, but at the expense of redraw time. At the lowquality setting, a screen-door effect achieves
transparency without sacrificing speed. At the mediumquality setting, blending improves image quality. At the
high-quality setting, blending and extra processing
produce an image free of visual artifacts, but at the cost
of drawing speed. Materials must also be turned on for
transparency to be visible.
Geometry
Determines how to display isolines in 3D and whether to display back faces
in 3D.
Configure: Geometry
Enter option [Isolines on top/Discard backfaces] <Isolines on top>: Specify an
option to configure
Configure: Isolines on top
Enter mode [ON/OFF] <ON>: Specify whether you want isolines on top
Configure: Discard backfaces
Enter mode [ON/OFF] <ON>: Specify whether you want back faces to be
discarded
24
|
Isolines on Top
Displays isolines for front and back faces in all shade
modes except Hidden. Isolines for the back faces are
displayed on top of the shading for the objects in 3D.
Turning this option off hides the isolines for the back
faces.
Discard Back
Faces
Discards back faces when drawing objects. You cannot
see the effect of discarding back faces on some objects,
such as spheres, because you cannot see the back face
even when it is present. The effect of discarding back
faces is visible on objects such as those that don’t have
a top. Discarding back faces enhances performance.
3DCONFIG
Acceleration
Specifies whether you want to use software or hardware acceleration in 3D.
Configure: Acceleration
Enter option [Hardware/Software/eXit] <Hardware>: Specify whether you want
to configure hardware or software
Configure: Hardware
Enter option [Driver name/Geometry acceleration/Antialias lines/eXit] <Driver
name>: Specify an option to configure

Configure: Geometry acceleration
Enter mode [ON/OFF] <ON>: Specify whether you want geometry acceleration
turned on or off
Configure: Antialias lines
Enter mode [ON/OFF] <ON>: Specify whether you want anti-alias lines turned
on or off
If you select Hardware, you can also specify whether geometry acceleration
and anti-alias lines are turned on or off.
Hardware
Specifies hardware acceleration. Select to use the
hardware graphics card to perform most of the drawing
tasks in 3D. This speeds up the drawing time.
When you select Hardware, the default driver is set to
the wopengl8.hdi driver that is included with AutoCAD.
If you select the Driver Name option, you can select a
driver from a list of available hardware-accelerated
drivers found in the AutoCAD drv directory. If you want
to use a hardware driver from another vendor, it must
be supported by the Heidi Graphics System.
Software
Specifies software acceleration. Select to use the
software graphics system to perform all of the drawing
tasks in 3D.
Geometry
Acceleration
Specifies whether to use geometry acceleration.
Geometry acceleration must be supported by your
graphics card. See your vendor documentation for
information on your graphics card.
3DCONFIG
|
25
Using geometry acceleration makes more efficient use
of the graphics card. With this option turned on, you
are drawing in single precision. Use this option only if
you know that your drawing is within the singleprecision limit.
Anti-alias Lines
Specifies using anti-aliasing lines. Lines appear
smoother and less gradient.
Exit
Exits the 3DCONFIG command.
3DCORBIT
Starts the interactive 3D view and enables you to set the objects in the 3D view into
continuous motion
3D Orbit toolbar:
Shortcut menu: Start the 3DORBIT command, right-click in the drawing area,
and choose More ➤ Continuous Orbit.
Command line: 3dcorbit
3DCORBIT changes the cursor to a sphere with two continuous lines encir-
cling it. Click in the drawing area and drag the pointing device in any
direction to start the objects moving in the direction that you’re dragging.
Release the button on the pointing device and the objects continue their
orbit in the direction that you specified. The speed of the cursor movement
determines the speed at which the objects spin.
You can change the direction of the continuous orbit by clicking and
dragging again. You can also change the display of the continuous orbit by
right-clicking in the drawing area and choosing an option from the shortcut
menu. For example, you can choose Visual Aids ➤ Grid to add a grid to the
view without exiting Continuous Orbit.

3DCORBIT
3DDISTANCE
Starts the interactive 3D view and makes objects appear closer or farther away
3DDISTANCE simulates the effect of moving the camera closer to the objects
or farther away. Unlike 3DZOOM, 3DDISTANCE does not exaggerate the per-
spective with which you view the objects or make them appear distorted.
3D Orbit toolbar:
Shortcut menu: Start the 3DORBIT command, right-click in the drawing area,
and choose More ➤ Adjust Distance.
Command line: 3ddistance
3DDISTANCE changes the cursor to a line with one arrow pointing up and one
pointing down. Clicking and dragging the cursor vertically toward the top of
the screen moves the camera closer to the objects, making them appear
larger. Clicking and dragging the cursor vertically toward the bottom of the
screen moves the camera away from the objects, making them appear
smaller.

See “Specify 3D Views Interactively (3D Orbit)” in the User’s Guide.
3DFACE
Creates a three-dimensional face
3DFACE creates a three- or four-sided surface anywhere in 3D space. You can
specify different Z coordinate values for each corner point of a 3D face, but
if you do, the 3D face cannot be extruded. 3DFACE differs from SOLID, which
creates a three- or four-sided surface that is parallel to the current user coordinate system (UCS) and cannot use different Z coordinate values for each
corner point. Also, 3DFACE creates a surface that is not filled in; SOLID creates
a filled-in surface.

Specify first point or [Invisible]: Specify a point (1) or enter i
First Point
Defines the start point for the 3D surface. After entering
the first point, enter the remaining points in a natural
clockwise or counterclockwise order to create a normal
3D face. If you locate all four points on the same plane,
AutoCAD creates a planar face that is similar to a region
object. When you shade or render the object, planar
faces are filled.
Invisible
Controls which edges of a 3D face are visible, allowing
for accurate modeling of objects with holes. Entering i
or invisible before the first point of an edge makes the
edge invisible.
The invisible specification must precede any object
snap modes, XYZ filters, or coordinate input for that
edge. You can create a 3D face in which all edges are
invisible. Such a face is a phantom; it does not appear
in wireframe presentations but can hide material in line
drawings. 3D faces do appear in shaded renderings.
You can combine 3D faces to model complex 3D surfaces.

Enter size of mesh in N direction: Enter a value between 2 and 256
N
Note 3DMESH is designed primarily for programmers. Other users should use
M
the 3D command.
AutoCAD defines a polygon mesh by a matrix, the size of which is determined by M and N size values. M × N equals the number of vertices that you
must specify.
Specify location for vertex (0, 0): Enter a 2D or 3D coordinate
AutoCAD defines the location of each vertex in the mesh by m and n, the row
and column indices of the vertex. Defining vertices begins with vertex (0,0).
You must supply the coordinate locations for each vertex in row m before
specifying vertices in row m + 1.
Vertices may be any distance from each other. The M and N orientation of a
mesh depends on the position of its vertices.
open mesh
3DMESH polygon meshes are always open in both M and N directions. You
can close a mesh with PEDIT.

Commands
EDGESURF, REVSURF, RULESURF, and TABSURF create
polygon meshes. PEDIT opens and closes a mesh, moves
selected vertices of a mesh, or fits a smooth surface to
mesh vertices. PFACE creates a general polygon mesh
called a polyface mesh. PROPERTIES edits edge visibility.
3D creates three-dimensional polygon mesh objects.
System Variables
SURFU and SURFV control the accuracy of surface
approximation in the M and N direction when you use
surface fitting. SURFTYPE controls the type of surface fitted by the Smooth option of the PEDIT command.
3DORBIT
Controls the interactive viewing of objects in 3D
3DORBIT enables you to manipulate the view of 3D objects by clicking and
dragging your pointing device.
You can view your entire drawing or select one or more objects before starting the command. Viewing the entire drawing may degrade the video
display.
You can display ambient, point, distant, and spot lights defined with the
LIGHT command in 3D Orbit view. To display these lights, you must set
SHADEMODE to Flat Shaded, Gouraud Shaded, Flat Shaded Edges On, or
Gouraud Shaded Edges On. The Wireframe and Hidden SHADEMODE options
do not display lights. To turn on lights, from the Tools menu, choose
Options. In the Options dialog box, choose the System tab. On the System
tab under Current 3D Graphics Display, choose Properties.
View menu: 3D Orbit
Command line: 3dorbit, 3do
3DORBIT activates a 3D view in the current viewport. If the user coordinate
system (UCS) icon is on, a shaded 3D UCS icon representing the current UCS
appears in the 3D Orbit view.
The 3D Orbit view displays an arcball, which is a circle divided into four
quadrants by smaller circles. When 3DORBIT is active, the target of the view
stays stationary and the camera location, or point of view, moves around the
target. The center of the arcball, not the center of the objects you’re
viewing, is the target point.
Note You cannot edit objects while the 3DORBIT command is active.
30

3DORBIT
Moving your cursor over different parts of the arcball changes the cursor
icon, indicating the direction in which the view rotates.
While the command is active, you can access additional 3DORBIT options
from a shortcut menu by right-clicking in the drawing area, or choosing
buttons on the 3D Orbit toolbar. See “3DOrbit Shortcut Menu” on page 32.
Cursor Icons
View rotation is determined by the placement and appearance of the cursor
as follows:

When you move the cursor inside the arcball, it
changes to a small sphere encircled by two lines. If you
click and drag in the drawing area you can move freely
around the objects. It works as if your cursor were
grabbing a sphere surrounding the objects and dragging
it around the target point. You can drag horizontally,
vertically, and diagonally using this method.
Circular Arrow
When you move the cursor outside the arcball, it
becomes a circular arrow. Clicking outside the arcball
and dragging the cursor around the arcball causes the
view to move around an axis that extends through the
center of the arcball, perpendicular to the screen. This
is called a roll.
If you drag the cursor into the arcball it changes to a
sphere encircled by two lines and the view moves freely.
If you move the cursor back outside the arcball, you
revert to a roll.
Horizontal Ellipse
When you move the cursor over one of the small circles
on the left or right side of the arcball, it becomes a
horizontal ellipse. Clicking and dragging from either of
these points rotates the view around the vertical or Y
axis through the middle of the arcball.
Vertical Ellipse
When you move the cursor over one of the small circles
on the top or bottom of the arcball, it becomes a vertical
ellipse. Clicking and dragging from either of these
points rotates the view around the horizontal or X axis
through the middle of the arcball.

never converge at a single point. The shapes in your
drawing always remain the same and do not appear
distorted when they are closer.
Perspective
Displays objects in perspective so that all parallel lines
converge at one point. Objects appear to recede into the
distance, and parts of the objects appear larger and
closer to you. The shapes are somewhat distorted when
the object is very close. This view correlates more
closely to what your eye sees.
Shading Modes

3DSIN
Imports a 3D Studio (3DS) file
3DSIN reads 3D Studio® geometry and rendering data (3DS files), including
meshes, materials, mapping, lights, and cameras. 3DSIN cannot import 3D
Studio procedural materials or smoothing groups.
Imported objects are assigned an AutoCAD color as close as possible to the
object’s 3D Studio color.
3D Studio lights are converted to the nearest AutoCAD equivalent. Ambient
light loses its color. Omni lights become point lights. Spotlights become
AutoCAD spotlights. 3D Studio cameras become AutoCAD named views.
If the name of any 3D Studio object conflicts with a name already in the
AutoCAD drawing, the 3D Studio name is assigned a sequence number to
resolve the conflict. The name might be truncated to resolve the conflict.

Save to Layers
Controls how 3D Studio objects are assigned to layers in the AutoCAD
drawing.
By Object
Creates a layer for each object in the 3D Studio file and
places the object on that layer. The name of the layer is
the same as the name of the object.
By Material
Creates a layer for each material in the 3D Studio file
and places objects to which that material is attached on
that layer. The name of the layer is the same as the
name of the material.
By Object Color
Creates a layer for each object color in the 3D Studio
file. AutoCAD places each 3D Studio object on the layer
corresponding to its color. The name of the layer is
COLORnn, where nn is the 3D Studio color index. If the
3D Studio file contains objects with no color, AutoCAD
places these objects on a layer called COLORNONE.
Single Layer
Creates a single layer called AVLAYER and places all
objects on that layer.
Multiple Material Objects
3D Studio assigns materials by face, element, or object. AutoCAD assigns
materials by object only. When AutoCAD encounters a 3D Studio object
assigned multiple materials, AutoCAD must find a way to handle the
assignment.
Always Prompt
Displays the Material Assignment Alert dialog box for each object with multiple materials. The dialog box displays the name of the object. The options
you select determine how 3DSIN handles the assignment. The options are as
follows:
Split Object by
Materials
38
|
3DSIN
Splits the object into multiple objects, one for each
material. This preserves the material assignments that
were made in the 3D Studio file. It also increases the
complexity of the drawing geometry.
Assign First
Material
Assigns the first material assigned to each multiplematerial object to the entire object. See the 3D Studio
documentation for an explanation of how the firstassigned material is determined.
Select a Material
Assigns one of the materials that was assigned to the
object in the 3D Studio file to the entire object. Select
the material from the list below this option, or choose
NONE to revert to the AutoCAD default material.
Split by Material
Splits all objects with multiple materials into multiple objects, one for each
material. This preserves the material assignments that were made in the 3D
Studio file. It also increases the complexity of the drawing geometry.
Assign First Material
Assigns the first material assigned to each multiple-material object to the
entire object. See the 3D Studio documentation for an explanation of how
the first-assigned material is determined.
Don’t Assign a Material
Assigns no material to each multiple-material object. This option loses all
material assignment information but preserves the 3D Studio geometry. The
object reverts to the AutoCAD default material.

3DSOUT
Exports to a 3D Studio (3DS) file
You can use AutoCAD geometry and rendering data with 3D Studio by converting a drawing to the 3DS file format with 3DSOUT.
3DSOUT exports only those AutoCAD objects with surface characteristics. A
line or an arc must have a nonzero thickness. A trace or a polyline must have
a nonzero width or thickness. Circles, polygon meshes, and polyface meshes
are always exported. Solids and 3D faces must have at least three unique
vertices. Geometry is tessellated on export, as necessary. AME® (Advanced
Modeling Extension® ) and AutoSurf ® objects must be converted to meshes
before you use 3DSOUT.
3DSOUT converts AutoCAD named views to 3D Studio cameras and Photo
Real or Photo Raytrace lights to the nearest 3D Studio equivalent. Point lights
become omni lights. Spotlights and distant lights become 3D Studio
spotlights.

Creates an object from the objects that share an ACI
number. The name of the new object is based on the
color.
AutoCAD Object
Type
Creates an object from all AutoCAD objects of the same
type. The name of the object is based on the AutoCAD
object type.
AutoCAD Blocks
Splits a block into its components and converts them to 3D Studio objects
according to the mode set under Derive 3D Studio Objects From.
Override (Each
Block Is One
Object)
Overrides the current Derive setting and converts each
block into a single 3D Studio object.
Smoothing
Assigns 3D Studio smoothing groups based on the controls set in this area.
Auto-Smoothing
Creates 3D Studio smoothing groups. If this option is
cleared, AutoCAD assigns no smoothing to new 3D
Studio objects.
Degrees
Specifies the threshold angle for smoothing. If the
angle between two face normals is greater than this
value, AutoCAD does not smooth the face normals.
Welding
Simplifies the geometry and improves rendering time by welding congruent
or nearby vertices into a single vertex.
Auto-Welding
Welds vertices. If this option is cleared, vertices remain
unchanged upon export.
Threshold
Specifies a distance in WCS coordinates of the
AutoCAD drawing. If the distance between two vertices
is less than or equal to this value, AutoCAD welds the
vertices into a single vertex. The default value is 0.001.
You can enter any positive value up to eight characters
in length. The decimal point can be in any location.

3DSWIVEL
Starts the interactive 3D view and simulates the effect of turning the camera
3D Orbit toolbar:
Shortcut menu: Start the 3DORBIT command, right-click in the drawing area,
and choose More ➤ Swivel Camera.
Command line: 3dswivel
3DSWIVEL changes the cursor to an arched arrow and simulates the effect of
turning a camera on a tripod. This command changes the target of the view.
For example, if you were pointing a camera at an object and then turned the
camera to the right, the object would move to the left in your viewing area.
Or, if you pointed the camera up, the objects would move down in your
viewing area. Swivel simulates this motion by using the cursor as the
camera’s viewfinder.
3DZOOM
Starts the interactive 3D view so you can zoom in and out on the view
3D Orbit toolbar:
Shortcut menu: Start the 3DORBIT command, right-click in the drawing area,
and choose Zoom.
Command line: 3dzoom
3DZOOM simulates the effect of a camera’s zoom lens. It makes objects appear
closer and farther away but does not change the position of the camera.
Zooming in magnifies the image. This also exaggerates the perspective with
which you view the objects if you’re using perspective projection. It may
slightly distort the shape of some objects.
Zoom changes the cursor to a magnifying glass with plus (+) and minus (–)
signs. Clicking and dragging the cursor vertically toward the top of the screen
zooms in on the image, making the objects appear larger or closer. Clicking
and dragging the cursor vertically toward the bottom of the screen zooms out
and makes the object appear smaller or farther away.

ALIGN
Aligns objects with other objects in 2D and 3D
Use ALIGN to move, rotate, or scale objects into alignment with other objects.
Add source points to the objects you want to align, and add destination points
to the objects to which you want the source objects to align. You can add up
to three pairs of source and destination points to align an object.

When you select two point pairs, you can move, rotate,
and scale the selected objects in 2D or 3D to align with
other objects.
The first set of source and destination points defines the
base point for the alignment (1, 2). The second set of
points defines the angle of rotation (3, 4).
After you enter the second set of points, AutoCAD
prompts you to scale the object. AutoCAD uses the
distance between the first and second destination
points (2, 4) as the reference length to which the object
is scaled. Scaling is available only when you are aligning
objects using two point pairs.
Note If you use two source and destination points to
perform a 3D alignment on nonperpendicular working
planes, you get unpredictable results.

Converts AME solid models to AutoCAD solid objects
Command line: ameconvert
Select objects:

The objects you select must be Advanced Modeling Extension (AME) Release
2 or 2.1 regions or solids. AutoCAD ignores all other objects.
Because of increased accuracy in the new AutoCAD solid modeler, AME
models may look slightly different after conversion. This difference is noticeable where the previous version of the AutoCAD solid modeler identified the
surfaces of two different shapes as so close as to be considered in the same
AMECONVERT

55
plane. The new AutoCAD solid modeler’s finer tolerance may interpret these
surfaces as being slightly offset. This phenomenon is most apparent with
aligned features such as fillets, chamfers, and through-holes.
Holes might become blind holes when the new modeler, with its much finer
approximation capability, interprets what was once a through-hole as being
slightly less wide than the solid. Typically, the length of the remaining solid
material is the difference between the tolerance of the previous modeler and
that of the new modeler.
Likewise, updated fillets or chamfers can occasionally be placed slightly
below the surface, creating a hole through the solid, leaving the original
shape unaltered. Also, drawing fillets or chamfers slightly above the original
surface creates an uneven transition between the solid and the fillet or
chamfer.
APERTURE
Controls the size of the object snap target box
Command line: aperture (or 'aperture for transparent use)
Object snap target height (1–50 pixels) <current>: Enter a value (1–50) or press
ENTER
Object snap applies only to objects inside or crossing the object snap target
box. The APBOX system variable controls whether the object snap target box
is displayed. The number of pixels you enter using APERTURE controls the size
of the object snap box. The higher the number, the larger the target box. You
can also change this setting in the Options dialog box, Drafting tab.

APPLOAD
Loads and unloads applications and defines which applications to load at startup
If you need to use applications that are not automatically loaded when you
start AutoCAD, you can use APPLOAD to load applications, unload applications, store a history list of applications you’ve loaded, and create a start-up
list of applications to be loaded each time you start AutoCAD.
You can load applications of the following file types:
■
■
■
■
■
■
AutoLISP® (.lsp)
ObjectARX™ (.arx)
VBA (.dvb)
ObjectDBX™ (.dbx)
Fast Load AutoLISP (.fas)
Visual LISP™ executables (.vlx)
Some ObjectARX applications require user interaction upon loading the
application and may not load properly with APPLOAD. Use the ARX command
to load these applications.
Tools menu: Load Application
Command line: appload
AutoCAD displays the Load/Unload Applications dialog box.
APPLOAD
|
57
Load/Unload Applications Dialog Box
Loads and unloads applications and specifies applications to be loaded at
start-up.
The options at the top of this dialog box are derived from the standard file
selection dialog box (see page 621). Following are descriptions of the additional options provided by the Load/Unload Applications dialog box:
Load
Loads or reloads the applications that are currently
selected in either the files list or on the History List tab.
Load is unavailable until you select a file that you can
load. AutoCAD loads ObjectARX, VBA, and DBX
applications immediately, but LSP, VLX and FAS
applications are queued and then loaded when you
close the Load/Unload Applications dialog box.
If you select a file that is already loaded, Load reloads
the application when applicable. You cannot reload
ObjectARX applications. In this case, you must first
unload the ObjectARX application, and then load it
again. The Load option is also available from a shortcut
menu by right-clicking a file on the History List tab.
58

APPLOAD
Loaded
Applications
Displays an alphabetical list (by file name) of currently
loaded applications. LISP routines are displayed in this
list only if you loaded them in the Load/Unload
Applications dialog box. You can drag files into this list
from the files list or from any application with dragging
capabilities, such as Microsoft® Windows® Explorer.
If you use the AutoCAD Web Browser to load an
application, the Web Browser downloads the
application to a temporary location on your machine.
This is the location from which AutoCAD loads the
application, as displayed in this list.
You can also unload certain applications from this list.
See the Unload option for details. Files that you cannot
unload are not available for selection.
History List
Displays an alphabetical list (by file name) of
applications that you previously loaded with Add To
History selected. You can drag files into this list from
the files list, or from any application with dragging
capabilities, such as Windows Explorer. If Add To
History is not selected when you drag files into this list,
the dragged files are loaded but not added to the history
list.
You can load and remove applications from this list, but
to unload applications, you must use the Loaded
Applications tab. See the Load, Unload, and Remove
options.
Add to History
Adds any applications that you load to the history list.
You may prefer to clear this option when loading
applications with the AutoCAD Web Browser, because
these applications are unavailable once the cache for
the application’s temporary location is emptied.
Unload
Unloads the selected applications. Unload is available
only when you select a file that you can unload on the
Loaded Applications tab. LISP applications cannot be
unloaded, nor can ObjectARX applications that are not
registered for unloading.
APPLOAD

Remove
Removes the selected applications from the history list.
Remove is available only when you select a file on the
History List tab. Note that Remove does not unload the
selected application. The Remove option is also
available from a shortcut menu by right-clicking an
application on the History List tab.
Startup Suite
Contains a list of applications that AutoCAD loads each
time you start AutoCAD. You can drag application files
from the files list, or from any application with
dragging capabilities such as Windows Explorer, into
the Startup Suite area to add them to the Startup Suite.
Click the Start-up Suite icon or Contents to display the
Startup Suite dialog box. You can also add files to the
Startup Suite by right-clicking an application on the
History List tab and choosing Add to Startup Suite from
the shortcut menu.
You cannot add applications that you load with the
AutoCAD Web Browser to the Startup Suite.

ARRAY
The specified distance between the rows and columns includes the corresponding lengths of the object to be arrayed.
Enter the distance between rows or specify unit cell (---):
To add rows downward, specify a negative value for the distance between
rows. AutoCAD skips the next prompt if you specify two points for the opposite corners of a rectangle.
Specify the distance between columns (|||):
To add columns to the left, specify a negative value for the distance between
columns. AutoCAD constructs rectangular arrays along a baseline defined by
the current snap rotation. This angle is normally 0, so the rows and columns
are orthogonal with respect to the X and Y drawing axes. The Rotate option
of the SNAP command changes the angle and creates a rotated array. The
SNAPANG system variable stores the snap rotation angle.
If you specify a large number of rows and columns for the array, AutoCAD
might take a while to create the copies. By default, the maximum number of
array elements that you can generate in one command is 100,000. The limit
is set by the MAXARRAY setting in the registry. To reset the limit to 200,000,
for example, enter (setenv "MaxArray" "200000") at the Command prompt.

Enter the number of items in the array: Enter a positive integer or press ENTER
If you enter a value for the number of items, you must specify either the
angle to fill or the angle between items. If you press ENTER (and do not provide the number of items), you must specify both.
Specify the angle to fill (+=ccw, -=cw) <360>: Enter a positive integer for a
counterclockwise rotation or a negative integer for a clockwise rotation
AutoCAD sees 0 as no response. You can enter 0 for angle to fill only if you
specify the number of items.
If you specify an angle to fill without providing the number of items, or if
you specify the number of items and enter 0 as the angle to fill or press
ENTER , AutoCAD prompts for the angle between items:
Angle between items: Specify an angle
If you specified the number of items and entered 0 as the angle to fill or
pressed ENTER , AutoCAD prompts for a positive or negative value to indicate
the direction of the array:
Angle between items (+=ccw, -=cw): Enter a positive integer for a
counterclockwise rotation or a negative integer for a clockwise rotation
AutoCAD determines the distance from the array’s center point to a reference
point on the last object selected. AutoCAD uses the center point of a circle or
arc, the insertion base point of a block or shape, the start point of text, and
one endpoint of a line or trace.
Rotate arrayed objects? <Y>: Enter y or n, or press ENTER
In a polar array, AutoCAD uses the reference point of the last object in the
selection set for all objects. If you defined the selection set by using window
or crossing selection, the last object in the selection set is arbitrary. Removing
an object from the selection set and adding it back forces that object to be
the last object selected. You can also make the selection set into a block and
replicate it.

ATTDEF
Creates an attribute definition
An attribute is informational text associated with a block. An attribute definition is a template for creating an attribute; it specifies the properties of an
attribute and the prompts displayed when the block is inserted.
When you finish defining the attribute, the attribute tag that you specified
is displayed in the drawing.
When you later include the attribute tag in a block definition using the
BLOCK command, AutoCAD erases the attribute tag from the drawing if you
have selected the Delete option in the Block Definition dialog box. When
you insert the block, AutoCAD displays the attribute value at the same location in the block, with the same text style and alignment.
Draw menu: Block ➤ Define Attributes
Command line: attdef
The Attribute Definition dialog box is displayed.
If you enter -attdef at the Command prompt, ATTDEF displays prompts on
the command line (see page 82).

Defines an environment in which you can create additional reflection and
refraction effects on objects with reflective, raytraced materials. With the
Photo Real renderer, the result is a mirrored effect; with the Photo Raytrace
renderer, the result is a raytraced environment.
Name
Specifies the image file name to create the raytraced
environment.
Use Background
Specifies that the selected objects in the current
drawing reflect the background you specify. If you use
an image file, the objects reflect that image rather than
the background image. You can use the following file
types for environment images: BMP, JPG, PCX, TGA,
and TIFF.
The program maps the environment onto a sphere
surrounding the scene, and the Photo Raytrace renderer
uses it in addition to the geometry to determine
reflections and refraction.

Adjust Background Bitmap Placement Dialog
Box
Controls options that apply to the background image. The Offset, Scale, and
Tiling controls all work the same as they do in the Adjust Material Bitmap
Placement dialog box (see page 865), except that they apply to the background image instead of a mapped material image. Offset and Scale refer to
X,Y coordinates, not U,V coordinates.
Offset and Scale
Sets the offset and scale. Offset values can range from −1 to 1 on either axis
(X or Y). Adjust a value by using the scroll bars to the right and below the
diagram (enclosed by the outer box labeled Offset), or by entering values in
X and Y Offset.
Scale values can range from ±0.1 to ±10 on either axis (X or Y). Adjust a value
by using the scroll bars to the left and above the diagram (enclosed by the
inner box labeled Scale), or by entering values in X and Y Scale.
Maintain Aspect Ratio
Locks the X and Y coordinates together. When Maintain Aspect Ratio is
turned on, moving one scroll bar moves the other, and a value you enter in
X or Y Scale changes the other.
Fit to Screen
Fits the image to your screen. If you select Use Image Aspect Ratio, the program fits the larger dimension to the screen while maintaining the image’s
aspect ratio.
Use Image Aspect Ratio
Uses the aspect ratio of the image file. You can still change Offset and Scale,
but the Maintain Aspect Ratio option is locked to the On setting.
Tiling
Controls how the bitmap is tiled with two radio buttons.
Tile
Tiles the bitmap (the default).
Crop
Does not tile the bitmap.
If you select Tile and you change the offset so the bitmap rectangle appears
outside the projection rectangle, the bitmap is not centered within the drawing area when you render it. (During tiling, the offset acts as a displacement,
not an absolute position.) However, if you select Crop, the bitmap is rendered
only where you place it, as indicated by the diagram (enclosed by the inner
100
|
BACKGROUND
box labeled Scale) in the Adjust Background Bitmap Placement dialog box. If
the diagram shows the bitmap outside the projection rectangle, the bitmap
does not appear in a rendering.
Center
Sets the Offset coordinates to 0 (centers the image).

BHATCH
Fills an enclosed area or selected objects with a hatch pattern or gradient fill
BHATCH first defines the boundaries of the area you want to hatch or fill,
either by computing a region or polyline boundary from a specified point
within an enclosed area, or by using selected objects as boundaries. It then
fills the boundaries with a hatch pattern, a solid color, or a gradient. BHATCH
creates an associative hatch or fill, which is updated when its boundaries are
modified, or a nonassociative hatch or fill, which is independent of its
boundaries. You can preview any hatch or fill and adjust the definition.
Due to the large number of combinations of geometry that you can hatch or
fill, editing hatched or gradient-filled geometry can produce unexpected
results. In this event, delete the object containing the hatch or fill and redo
the hatch or fill.
Note By default, AutoCAD won’t create a hatch pattern that consists of over
10,000 segments. The limit is set by the MaxHatch setting in the registry. To
reset the limit to 50,000, for example, enter (setenv "MaxHatch" "50000") at
the Command prompt. The limit can be reset to any value between 100 and
10,000,000.

BHATCH
Command line: bhatch
The Boundary Hatch and Fill dialog box is displayed.
If you enter -bhatch at the Command prompt, BHATCH displays prompts on
the command line (see page 117).
Boundary Hatch and Fill Dialog Box
Defines the boundary, pattern type, pattern properties, and attributes for
hatch and gradient fill objects.
The Boundary Hatch and Fill dialog box includes the following tabs:
Pick Points
Determines a boundary from existing objects visible on the screen. The
objects must form an enclosed area. How AutoCAD detects objects using this
option depends on which island detection method is selected on the
Advanced tab. For example, if the island detection method is Flood,
AutoCAD detects objects within the outermost boundary as islands and
includes them in the boundary definition. The island detection style (which
you also set on the Advanced tab) then determines how to hatch the detected
islands.
When you select Pick Points, the dialog box closes temporarily, and
AutoCAD displays a prompt.
Select internal point: Specify a point within the area to be hatched or filled
Select internal point: Specify a point, enter u or undo to undo the last selection,
or press ENTER to end point specification and return to the dialog box
While specifying points, you can right-click in the drawing area at any time
to display a shortcut menu. You can undo the last or all point specifications,
change the selection method, change the island detection style, or preview
the hatch or gradient fill.

Inherit Properties
Hatches or fills specified boundaries using the hatch or fill properties of one
object. After selecting the associative hatch or fill object whose properties
you want the hatch or fill to inherit, you can right-click in the drawing area
and use the shortcut menu to toggle between the Select Objects and Pick
Points options to create boundaries.
See “Pick Points” on page 107 and “Select Objects” on page 108.
Double
For user-defined patterns, draws a second set of lines positioned at 90 degrees
to the original lines, creating a crosshatch. AutoCAD stores this information
in the HPDOUBLE system variable. This option is available only if you set Type
to User Defined on the Hatch tab.
This option is not available for gradient fills.
Composition
Controls whether the hatch or gradient fill is associative or nonassociative.
Associative
Creates a hatch or fill that is updated when you modify
its boundaries.
Nonassociative
Creates a hatch or fill that is independent of its
boundaries.
Preview
Temporarily dismisses the dialog box and displays the currently defined
boundaries with the current hatch or fill settings. This option is not available

109
HatchTab (Boundary Hatch and Fill Dialog Box)
Defines the appearance of the hatch pattern to be applied.
Type
Sets the pattern type.
Predefined
Specifies a predefined AutoCAD pattern. These patterns
are stored in the acad.pat and acadiso.pat files. You can
control the angle and scale of any predefined pattern.
For predefined ISO patterns, you can also control the
ISO pen width.
Note When you use the Solid predefined pattern, the
boundary must be closed and must not intersect itself. In
addition, if the hatch area contains more than one loop,
the loops must not intersect. These limitations do not
apply to standard hatch patterns.
110
|
User Defined
Creates a pattern of lines based on the current linetype
in your drawing. You can control the angle and spacing
of the lines in your user-defined pattern.
Custom
Specifies a pattern that is defined in any custom PAT file
that you have added to the AutoCAD search path. (To
use the patterns in the supplied acad.pat and acadiso.pat
files, choose Predefined.) You can control the angle and
scale of any custom pattern.
BHATCH
Pattern
Lists the available predefined patterns. The six most recently used predefined
patterns appear at the top of the list. AutoCAD stores the selected pattern in
the HPNAME system variable. The Pattern option is available only if you set
Type to Predefined.
The [...] button displays the Hatch Pattern Palette dialog box (see page 116),
in which you can view preview images for all predefined patterns at once to
help you make a selection.
Swatch
Displays a preview of the selected pattern. You can click the swatch to display
the Hatch Pattern Palette dialog box (see page 116). When the SOLID pattern
is selected, you can click the right arrow to display a list of colors or the Select
Color dialog box (see page 169).
Custom Pattern
Lists the available custom patterns. The six most recently used custom patterns appear at the top of the list. AutoCAD stores the selected pattern in the
HPNAME system variable. The Custom Pattern option is available only if you
set Type to Custom.
The [...] button displays the Hatch Pattern Palette dialog box (see page 116),
in which you can view preview images for all custom patterns at once to help
you make a selection.
Angle
Specifies an angle for the hatch pattern relative to the X axis of the current
UCS. AutoCAD stores the angle in the HPANG system variable.
Scale
Expands or contracts a predefined or custom pattern. AutoCAD stores the
scale in the HPSCALE system variable. This option is available only if you set
Type to Predefined or Custom.
Relative to Paper Space
Scales the hatch pattern relative to paper space units. Using this option, you
can easily display hatch patterns at a scale that is appropriate for your layout.
This option is available only from a layout.
Spacing
Specifies the spacing of lines in a user-defined pattern. AutoCAD stores the
spacing in the HPSPACE system variable. This option is available only if you
set Type to User Defined.
BHATCH
|
111
ISO Pen Width
Scales an ISO predefined pattern based on the selected pen width. This
option is available only if you set Type to Predefined and set Pattern to one
of the available ISO patterns.
Advanced Tab (Boundary Hatch and Fill Dialog Box)
Defines how AutoCAD creates and hatches or fills boundaries.
Island Detection Style
Specifies the method used to hatch or fill objects within the outermost
boundary. If no internal boundaries exist, specifying an island detection style
has no effect. Because you can define a precise set of boundaries, it’s often
best to use the Normal style.
112
|
BHATCH
.
.
Normal
Hatches or fills inward from the outer boundary. If
AutoCAD encounters an internal intersection, it turns
off hatching or filling until it encounters another
intersection. Thus, areas separated from the outside of
the hatched or filled area by an odd number of
intersections are hatched or filled, and areas separated
by an even number of intersections are not. You can
also set the Normal style by adding ,N to the pattern
name in the HPNAME system variable.
Outer
Hatches or fills inward from the outer boundary.
AutoCAD turns hatching or filling off if it encounters
an internal intersection. Because this process starts
from both ends of each hatch or fill line, AutoCAD
hatches or fills only the outermost level of the structure
and leaves the internal structure blank. You can also set
the Outer style by adding ,O to the pattern name in the
HPNAME system variable.
Ignore
Ignores all internal objects and hatches or fills through
them. You can also set the Ignore style by adding ,I to
the pattern name in the HPNAME system variable.
Note Hatching concave curves with the Outer and Ignore styles can cause
hatching discrepancies.
The Normal, Outer, and Ignore options are also available from a shortcut
menu by right-clicking in the drawing area while you specify points or select
objects to define your boundaries.
Object Type
Specifies whether to retain boundaries as objects, and the object type that
AutoCAD applies to those objects.
BHATCH
|
113
Retain
Boundaries
Adds the temporary boundary objects to the drawing.
Object Type
Controls the type of the new boundary object.
AutoCAD creates the boundary as a region or a
polyline. This option is available only if you select
Retain Boundaries.
For more information about regions, see “Create and
Combine Areas (Regions)” in the User’s Guide.
Boundary Set
Defines the set of objects AutoCAD analyzes when defining a boundary from
a specified point. The selected boundary set has no effect when you use Select
Objects to define a boundary.
By default, when you use Pick Points to define a boundary, AutoCAD
analyzes all objects visible in the current viewport. By redefining the boundary set, you can disregard certain objects when defining boundaries without
having to hide or remove those objects. For large drawings, redefining the
boundary set can also produce the boundary faster because AutoCAD
examines fewer objects.
Current Viewport
Defines the boundary set from everything visible in the
current viewport. Selecting this option discards any
current boundary set and uses everything visible in the
current viewport.
Existing Set
Defines the boundary set from the objects that you
selected with New. If you have not created a boundary
set with New, the Existing Set option is not available.
New
Prompts you to select the objects that define the
boundary set. AutoCAD includes only the hatchable or
fillable objects you select when it constructs the new
boundary set. AutoCAD discards any existing boundary
set, replacing it with the new boundary set defined by
the objects you select. If you don’t select any objects,
AutoCAD retains any current set.
Until you exit BHATCH or create a new boundary set,
AutoCAD ignores objects that do not exist in the
boundary set when you define your boundaries by
using Pick Points.
Island Detection Method
Specifies whether to include objects within the outermost boundary as
boundary objects. These internal objects are known as islands.
114
|
BHATCH
Flood
Includes islands as boundary objects.
Ray Casting
Runs a line from the point you specify to the nearest
object and then traces the boundary in a
counterclockwise direction, thus excluding islands as
boundary objects.
Gradient Tab (Boundary Hatch and Fill Dialog Box)
Defines the appearance of the gradient fill to be applied.
One Color
Specifies a fill that uses a smooth transition between darker shades and
lighter tints of one color. When One Color is selected, AutoCAD displays a
color swatch with Browse button and a Shade and Tint slider. (GFCLRSTATE
system variable)
Two Color
Specifies a fill that uses a smooth transition between two colors. When Two
Color is selected, AutoCAD displays a color swatch with a Browse button for
color 1 and for color 2. (GFCLRSTATE system variable)
Color Swatch
Specifies the color for the gradient fill. Click the Browse button [...] to display
the Select Color dialog box, where you can select an AutoCAD Index color,
true color, or color book color. The default color displayed is the current color
in the drawing.
BHATCH
|
115
Shade and Tint Slider
Specifies the tint (the selected color mixed with white) or shade (the selected
color mixed with black) of a color to be used for a gradient fill of one color.
(GFCLRLUM system variable)
Centered
Specifies a gradient configuration that is symmetrical. If this option is not
selected, the gradient fill is shifted up and to the left, creating the illusion of
a light source to the left of the object. (GFSHIFT system variable)
Angle
Specifies the angle of the gradient fill. The specified angle is relative to the
current UCS. This option is independent of the angle specified for hatch patterns. (GFANG system variable)
Gradient Patterns
Displays nine fixed patterns for gradient fills. These patterns include linear
sweep, spherical, and parabolic. (GFNAME system variable)

Creates a boundary set from a selection set you define.
Select objects: Use an object selection method
Everything
Creates a boundary set from everything visible in the
current viewport. Selecting this option discards any
current boundary set and uses everything visible in the
drawing or in the current viewport.
Retain Boundary
Specifies whether to add the temporary boundary objects to the drawing
after hatching is completed.
Retain derived boundaries? [Yes/No] <current>: Enter y or n, or press ENTER
Island Detection
Specifies whether to use objects within the outermost boundary as boundary
objects.
Do you want island detection? [Yes/No] <current>: Enter y or n, or press ENTER
Specifying no island detection prompts for the ray casting method.

option or press ENTER
Nearest
Runs a line from the point you specify to the nearest
object and then traces the boundary in a
counterclockwise direction.
+X
Runs a line in the positive X direction from the point
you specify to the first object encountered and then
traces the boundary in a counterclockwise direction.
-X
Runs a line in the negative X direction from the point
you specify to the first object encountered and then
traces the boundary in a counterclockwise direction.
+Y
Runs a line in the positive Y direction from the point
you specify to the first object encountered and then
traces the boundary in a counterclockwise direction.
-Y
Runs a line in the negative Y direction from the point
you specify to the first object encountered and then
traces the boundary in a counterclockwise direction.

Style
Specifies the method used to hatch objects within the outermost hatch
boundary. If you have selected no internal objects, a hatching style has no
effect. Because you can define a precise set of boundaries, it’s often best to use
the Normal style.
Enter hatching style [Ignore/Outer/Normal] <current>:
Enter an option or press
ENTER
Ignore
Ignores all internal objects and hatches through them.
AutoCAD stores the Ignore style code by adding, I to the
pattern name in the HPNAME system variable.
Outer
Hatches inward from the outer boundary. AutoCAD
turns hatching off if it encounters an internal
intersection and doesn’t turn it back on. Because this
process starts from both ends of each hatch line,
AutoCAD hatches only the outermost level of the
structure and leaves the internal structure blank.
AutoCAD stores the Outer style code by adding ,O to
the pattern name in the HPNAME system variable.
Normal
Hatches inward from the outer boundary. If AutoCAD
encounters an internal intersection, it turns off
hatching until it encounters another intersection.
Thus, areas separated from the outside of the hatched
area by an odd number of intersections are hatched,
while areas separated by an even number of
intersections are not. AutoCAD stores the Normal style
code by adding ,N to the pattern name in the HPNAME
system variable.
Associativity
Specifies that the new hatch pattern is updated when its boundaries are modified. Hatching created with BHATCH is, by default, associative.
Do you want associativity? [Yes/No] <current>: Enter y or n, or press ENTER

as a block
The insertion base point becomes the origin of the block’s coordinate system,
which is parallel to the UCS in effect at the time that you define the block.
When you insert the block into a drawing, its coordinate system is aligned
parallel to the current UCS. Thus, you can insert a block at any orientation
in space by setting the UCS first.

Second Break
Point
Specifies the second point for AutoCAD to use to break
the object.
First Point
Overrides the original first point with the new point
that you specify.
Specify first break point:
Specify second break point:
AutoCAD erases the portion of the object between the two points that you
specify. If the second point is not on the object, AutoCAD selects the nearest
point on the object; therefore, to break off one end of a line, arc, or polyline,
specify the second point beyond the end to be removed.
To split an object in two without erasing a portion, enter the same point for
both the first and second points. You can do this by entering @ to specify the
second point.
Lines, arcs, circles, polylines, ellipses, splines, donuts, and several other
object types can be split into two objects or have one end removed.
AutoCAD converts a circle to an arc by removing a piece of the circle starting
counterclockwise from the first to the second point.

CAL
Evaluates mathematical and geometric expressions
Command line: cal (or 'cal for transparent use)
CAL is an online geometry calculator that evaluates point (vector), real, or
integer expressions. The expressions can access existing geometry using the
object snap functions such as CEN, END, and INS. You can insert AutoLISP®
variables into the arithmetic expression and assign the value of the expression back to an AutoLISP variable. You can use these arithmetic and vector
expressions in any AutoCAD® command that expects points, vectors, or
numbers.
Understanding Syntax of Expressions
CAL evaluates expressions according to standard mathematical rules of
precedence:
■
■
■
Expressions in parentheses first, starting with the innermost set
Operators in standard order: exponents first, multiplication and division
second, and addition and subtraction last
Operators of equal precedence from left to right
Numeric Expressions
Numeric expressions are real integer numbers and functions combined with
the operators in the following table.

()
Groups expressions
&
Determines the vector product of vectors (as a vector)
[a,b,c]&[x,y,z] = [ (b*z) – (c*y) , (c*x) – (a*z) , (a*y) – (b*x) ]
*
Determines the scalar product of vectors (as a real number)
[a,b,c]*[x,y,z] = ax + by + cz
*, /
Multiplies, divides a vector by a real number
a*[x,y,z] = [a*x,a*y,a*z]
+,–
Adds, subtracts vectors (points)
[a,b,c] + [x,y,z] = [a+x,b+y,c+z]
The following are examples of vector expressions:
A+[1,2,3] provides the point positioned [1,2,3] units relative to point A.
The expression
[2<45<45] + [2<45<0] – [1.02, 3.5, 2]
adds two points and subtracts a third point. The first two points are in
spherical coordinates.
Formatting Feet and Inches
Enter feet and inches using the following format:
feet'-inches" or feet'inches"
The expression converts to a real number based on inches, as shown in the
following examples:
136
|
CAL
2'-5" converts to 2*12+5 = 29
5" converts to 0*12+5 = 5
2' converts to 2*12+0 = 24
Formatting Angles
The default units for angles are decimal degrees. Enter angles using the
following format:
degdmin'sec"
You must enter 0 and d (0d) when entering an angle that is less than 1 degree
(minutes and seconds only). You can omit the minutes or seconds if they are
zero.
Enter a number followed by r to enter angles in radians. Enter a number followed by g to enter angles in grads.
The following examples show ways of entering angles:
124.6r
14g
5d10'20"
0d10'20"
AutoCAD converts angles entered in any format to decimal degrees.
Pi radians is equal to 180 degrees, and 100 grads is equal to 90 degrees.
Using Points and Vectors
Both points and vectors are pairs or triples of real numbers. A point defines
a location in space, but a vector defines a direction (or translation) in space.
Some CAL functions, such as pld and plt, return a point. Other functions,
such as nor and vec, return a vector.
Formatting Points and Vectors
A point or vector is a set of three real expressions enclosed in brackets ([ ]):
[r1,r2,r3]
The notation p1, p2, and so forth designates points. The notation v1, v2, and
so forth designates vectors. In drawings, points are displayed as dots, and vectors are displayed as lines with arrows.

The following are valid points:
[1,2] is the same as [1,2,0]
[,,3] is the same as [0,0,3]
[ ] is the same as [0,0,0]
In the following example, the point is entered in the relative spherical coordinate system with respect to the WCS. The distance is 1+2=3; the angles are
10+20=30 degrees and 45 degrees, 20 minutes.
[@*1+2<10+20<45d20"]
The following is a valid point that contains arithmetic expressions as its
components:
[2*(1.0+3.3),0.4–1.1,2*1.4]
The following example uses the Endpoint object snap and the vector [2,0,3]
to calculate a point that is offset from a selected endpoint.
end + [2,,3]
The calculated point is offset two units in the X direction and three units in
the Z direction relative to the selected endpoint.

CAL
Using AutoLISP Variables
You can use AutoLISP variables within arithmetic expressions. The variables
must be one of the following types: real, integer, or 2D or 3D point (vector).
This example defines a point positioned 5 units in the X direction and 1 unit
in the Y direction from the point stored in AutoLISP variable A.
A+[5,1]
If you enter an AutoLISP variable with a name containing a character with
special meaning in CAL, such as +, –, *, or /, enclose the variable name in
apostrophes ('), for example:
'number-of-holes'
Assigning Values to AutoLISP Variables
To assign a value to an AutoLISP variable, precede the arithmetic expression
with the variable name and the equal sign (=). Later, you can use the value of
this variable for other calculations.
This example saves the values of two expressions in AutoLISP variables P1
and R1.
Command: cal
>> Expression: P1=cen+[1,0]
>> Select entity for CEN snap: Select a circle or an arc
Command: cal
>> Expression: R1=dist(end,end)/3
>> Select entity for END snap: Select an object with an endpoint
This example uses the values of variables P1 and R1:
Command: circle
Specify center point for circle or [3P/2P/Ttr (tangent tangent radius)]:
>> Expression: P1+[0,1]
Specify radius of circle or [Diameter] <last>: 'cal
>> Expression: R1+0.5
'cal
Using AutoCAD System Variables
You can use the getvar AutoLISP function to read the value of an AutoCAD
system variable.
The syntax is
(getvar "variable_name")
CAL
|
139
The following example uses getvar to obtain the point that is the center of
the view in the current viewport.
(setq c (getvar "viewctr"))
Converting Units of Measurement
The cvunit AutoLISP function converts either a number or a point from one
unit of measurement to another. See the Support/acad.unt file for a list of units
that you can convert. The syntax is
cvunit(value, from_unit, to_unit)
The following example converts the value 1 from inches to centimeters:
cvunit(1,inch,cm)

Calculating the Length of a Vector
The abs function calculates the length of a vector.
abs(v)
Calculates the length of vector v, a nonnegative real
number.
In spherical coordinates (dist<ang<ang), the dist is the
length of the vector.
The following example calculates the length of the
vector [1,2,3]:
abs([1,2,3])
Obtaining a Point by Cursor
To enter a point using the pointing device, use the cur function. AutoCAD
prompts you to specify a point and uses the coordinate values of the point in
the expression. The point coordinate values are expressed in terms of the
current UCS. The cur function sets the value of the AutoCAD variable
LASTPOINT.
The following example adds the vector [3.6,2.4,0]—the result of 1.2*[3,2]—
to the point you select. This expression produces a point that is offset from
the selected point.
cur+1.2*[3,2]
Obtaining the Last-Specified Point
Use the @ character in the expression to obtain the coordinate of the last
point, as shown in the following example:
Command: line
Specify first point: 'cal
>> Expression: cen+[0,1]
>> Select entity for CEN snap: Select a circle or an arc
Specify next point or [Close/Undo]: 'cal
>> Expression: @+3*vec1(cen,cen)
The first point of the line is one unit in the Y direction from the center of the
first selected circle. The second point of the line is three units away from the
first point. The direction of the line is from the center of the first selected circle to the center of the second selected circle.

Using AutoCAD Snap Modes in Arithmetic
Expressions
You can use the AutoCAD Snap modes as parts of arithmetic expressions.
AutoCAD prompts you to select an object and returns the coordinate of the
appropriate snap point. Using arithmetic expressions with Snap modes
greatly simplifies entering coordinates relative to other objects.
When you use these Snap modes, enter only the three-character name. For
example, when you use the Center Snap mode, enter cen. CAL Snap modes
set the value of the LASTPOINT system variable.

CAL
Using the Midpoint Snap mode, in the following example CAL prompts for
an object and returns a point one unit in the Y direction from the midpoint
of the selected object:
mid+[,1]
The following example uses the Endpoint Snap mode to calculate the centroid of a triangle defined by three endpoints:
(end+end+end)/3
Converting Points between UCS and WCS
Normally, AutoCAD assumes all coordinates to be relative to the current
UCS. The following functions convert points between UCS and WCS.
w2u(p1)
Converts point p1 expressed in the WCS to the current
UCS.
u2w(p1)
Converts point p1 expressed in the current UCS to the
WCS.
You can use w2u to find the WCS origin in terms of the current UCS:
w2u([0,0,0])

taken from point a and the Z coordinate value from point b:
xyof(a)+zof(b)
Calculating a Point on a Line
The plt and pld functions return a point on a given line. You can specify the
position of the point on the line either by its distance from the first point or
parametrically by a t parameter.
pld(p1,p2,dist)
Calculates a point on the line passing through points p1
and p2. The parameter dist defines the distance of the
point from the point p1.
plt(p1,p2,t)
Calculates a point on the line passing through points p1
and p2. The parameter t defines the parametric position
of the point on the line.
The following are examples of the parameter t:
If t=0 the point is p1
If t=0.5 the point is the midpoint between p1 and p2
If t=1 the point is p2
Rotating a Point About an Axis
The rot function rotates a point about an axis and returns the resulting point.

(p1,p2) and (p3,p4). AutoCAD considers all points
three-dimensional.
ilp(p1,p2,p3,p4,
p5)
Determines the intersection point between a line
(p1,p2) and a plane passing through three points
(p3,p4,p5).
Calculating a Distance
dist(p1,p2)
Determines the distance between two points, p1 and p2.
This is the same as the vector expression abs(p1–p2).

Obtaining an Angle
The ang function determines the angle between two lines. Angles are
measured counterclockwise with respect to either the X axis, in the twodimensional case, or to a user-specified axis, in the three-dimensional case.
ang(v)
Determines the angle between the X axis and vector v.
The vector v is considered 2D, projected on the XY
plane of the current UCS.
ang(p1,p2)
Determines the angle between the X axis and the line
(p1,p2), oriented from p1 to p2. The points are
considered 2D, projected on the XY plane of the current
UCS.
ang(apex,p1,p2)
Determines the angle between lines (apex,p1) and
(apex,p2). The points are considered 2D, projected on
the XY plane of the current UCS.
CAL

149
ang(apex,p1,p2,
p)
Determines the angle between lines (apex,p1) and
(apex,p2). The lines are considered 3D. The last
parameter, point p, is used to define the orientation of
the angle. The angle is measured counterclockwise with
respect to the axis going from apex to p.
The following examples show how angles are measured.

Select the apex of the angle, and then select the two opposite vertices.
Calculating a Normal Vector
The nor function calculates the unit normal vector (a vector perpendicular to
a line or plane), not a point. The vector defines the direction of the normal,
not a location in space. You can add this normal vector to a point to obtain
another point.
150

CAL
nor
Determines the three-dimensional unit normal vector
of a selected circle, arc, or polyline arc segment. This
normal vector is the Z coordinate of the object
coordinate system (OCS) of the selected object.
nor(v)
Determines the two-dimensional unit normal vector to
vector v. Both vectors are considered 2D, projected on
the XY plane of the current UCS. The orientation of the
resulting normal vector points to the left of the original
vector v.
nor(p1,p2)
Determines the 2D unit normal vector to line p1,p2.
The line is oriented from p1 to p2. The orientation of
the resulting normal vector points to the left from the
original line (p1,p2).
nor(p1,p2,p3)
Determines the 3D unit normal vector to a plane
defined by the three points p1, p2, and p3. The
orientation of the normal vector is such that the given
points go counterclockwise with respect to the normal.

True Color Tab (Select Color Dialog Box)
Specifies color settings using true colors (24-bit color) with either the Hue,
Saturation, and Luminance (HSL) color model or the Red, Green, and Blue
(RGB) color model. Over sixteen million colors are available when using true
color functionality.
HSL Color Model
Specifies to use the HSL color model for selecting colors. The options available on the True Color tab are dependent on whether the HSL or RGB color
model is specified.
Hue, saturation, and luminance are properties of colors. By manipulating the
values of these properties, you can specify a wide range of colors.
Hue
Specifies the hue of a color. Hues represent a specific
wavelength of light within the visible spectrum. To
specify a hue, move the crosshairs (from side to side)
over the color spectrum or specify a value in the Hue
box. Adjusting this value effects the RGB value. Valid
hue values are from 0 to 360 degrees.
Saturation
Specifies the purity of a color. High saturation causes a
color to look more pure while low saturation causes a
color to look washed-out. To specify color saturation,
move the crosshairs (from top to bottom) over the color
spectrum or specify a value in the Saturation box.
Adjusting this value effects the RGB value. Valid
saturation values are from 0 to 100%.
COLOR
|
171
Luminance
Specifies the brightness of a color. To specify color
luminance, adjust the bar on the color slider or specify
a value in the Luminance box. Valid luminance values
are from 0 to 100%. A value of 0% represents the color
black, 100% represents white, and 50% represents the
optimal brightness for the color. Adjusting this value
also affects the RGB value.
RGB Color Model
Specifies to use the RGB color model for selecting colors. The options available on the True Color tab are dependent on whether the HSL or RGB color
model is specified.
Colors can be broken down into components of red, green, and blue. The values specified for each component represent the intensity of the red, green,
and blue components. The combination of these values can be manipulated
to create a wide range of colors.
Red
Specifies the red component of a color. Adjust the slider
on the color bar or specify a value from 1 to 255 in the
Red box. If this value is adjusted, it will be reflected in
the HSL color mode values.
Green

slider on the color bar or specify a value from 1 to 255
in the Green box. If this value is adjusted, it will be
reflected in the HSL color mode values.
Blue
Specifies the blue component of a color. Adjust the
slider on the color bar or specify a value from 1 to 255
in the Blue box. If this value is adjusted, it will be
reflected in the HSL color mode values.
Color
Specifies the RGB color value. This option is updated when changes are made
to HSL or RGB options. You can also edit the RGB value directly using the following format: 000,000,000.
True Color Stored as RGB
Indicates the value for each RGB color component.

display the name of the selected color book.
Color Book
Specifies the color book to be used when selecting colors. You can select a
color book from the drop-down list. This list consists of all the color books
that are found in the Color Book Locations specified in the Options dialog
box.
To load a color book, use the Color Book Locations option in the Options dialog box, on the Files tab. The default location for color books is
\support\color. If there are no color books installed, the Color Book dropdown list is unavailable.
When you select a color book, the colors and the assigned color names are
displayed. AutoCAD supports color books containing up to 10 colors per
page. If a color book is not paginated, AutoCAD organizes the colors into
pages containing 7 colors per page.
To navigate through color book pages, select an area on the color slider or use
the up and down arrows to browse the color book. The corresponding colors
and color names are displayed by page as you navigate through the color
book.
RGB Equivalent

You can enter a color from the AutoCAD Color Index (a color name or number), a true color, or a color from a color book.
You can enter the color number (1 through 255) or the color name (the
names for the first seven colors). For example, you can specify the color red
by entering the ACI number 1 or the ACI name red.
You can also enter bylayer or byblock. If you enter byblock, AutoCAD draws
all new objects in the default color (white or black, depending on your background color) until they are grouped into a block. When you insert the block
in a drawing, the objects in the block inherit the current setting of COLOR.
Warning! If you used a mixture of color methods to draw the objects that
make up a block, inserting that block or changing its color produces complex
results.
If you enter bylayer, new objects assume the color assigned to the layer on
which you create them. See the LAYER command for information about
assigning a color to a layer.
True Color
Specifies a true color to be used for the selected object.
Red, Green, Blue: Enter three integer values from 0 to 255 separated by commas
to specify a true color
Color Book

COMPILE
Compiles shape files and PostScript font files
Before you can use AutoCAD shape files as fonts or shapes in a drawing, you
must compile or convert them into SHX files. You can then use LOAD to
insert the SHX files into a drawing. Compiling PostScript font PFB files
improves the loading speed of drawings that use them.
Command line: compile
AutoCAD displays the Select Shape or Font File dialog box (a standard file
selection dialog box). Enter the SHP or PFB file name in the dialog box.
AutoCAD compiles it into a file with this name, and automatically adds the
file name extension .shx.

CONVERT
Optimizes 2D polylines and associative hatches created in AutoCAD Release 13 or earlier
Since Release 14, AutoCAD creates 2D polylines and associative hatches
using an optimized format that saves memory and disk space. Use CONVERT
to update hatches or polylines created in releases earlier than AutoCAD R14
or AutoCAD LT 97.
Command line: convert

hatch pattern may not be updated properly if you have changed the UCS
since creating the hatch. When updating hatches with CONVERT, it is recommended that you use the Select option so that you can check your results.
In most cases, you do not need to update polylines with CONVERT. By default,
the PLINETYPE system variable specifies that polylines are updated automatically when you open an older drawing. Polylines may be created in the old
format by third-party applications, and they may be contained in an older
drawing that was inserted as a block and then exploded.
Note Polylines containing curve-fit or splined segments always retain the old
format, as do polylines that store extended object data on their vertices.
AutoCAD editing commands make no distinction between the two formats.
See Also
Commands
BHATCH fills an enclosed area with a hatch pattern.
HATCH fills a specified boundary with a pattern. PEDIT
edits polylines and three-dimensional polygon meshes.
PLINE creates two-dimensional polylines.
System Variables
PLINETYPE specifies whether AutoCAD uses optimized
2D polylines.
CONVERTCTB
Converts a color-dependent plot style table (CTB) to a named plot style table (STB)
Command line: convertctb
Displays the Select File dialog box (a standard file selection dialog box),
where you can select the color-dependent plot style table file you want to
convert. The Save As dialog box is then displayed. If necessary, specify a new
location or name for the converted plot style table file.
CONVERTCTB saves a copy of a color-dependent plot style table as a named
plot style table, which you can then attach to drawings that use named plot
styles. The original color-dependent plot style table is not affected by
CONVERTCTB. The default location for the new named plot style table file is
in the AutoCAD Plot Styles folder. The default name for the new named plot
style table file is the same as the color-dependent plot style table name.
CONVERTCTB creates one named plot style for each color that has unique plot
properties, one named plot style for each group of colors that are assigned the
same plot properties, and a default named plot style called NORMAL.
CONVERTCTB
|
179
For example, if all the colors in a color-dependent plot style table have the
same plot properties, CONVERTCTB creates only two named plot styles in the
named plot style table: NORMAL, the default plot style, and STYLE 1, which
assumes the plot properties that were assigned to all the colors in the colordependent plot style table. However, suppose all the colors in a color-dependent plot style table have the same plot properties except for two colors, BLUE
and GREEN. If these colors each have unique plot properties, CONVERTCTB
creates four named plot styles in the named plot style table: NORMAL, the
default plot style; STYLE 1, which assumes the plot properties of GREEN; STYLE
2, which assumes the plot properties of BLUE; and STYLE 3, which assumes the
plot properties that were assigned to all the other colors.
CONVERTCTB gives the plot styles in the new named plot style table generic
names such as STYLE 1, STYLE 2. You can modify these generic plot style
names in the the Plot Style Table Editor. Click the Edit button on the Plot
Device tab in the Page Setup dialog box. If you want to rename the plot
styles, you must do so before applying them to drawing layouts.
CONVERTPSTYLES
Converts the current drawing to either named or color-dependent plot styles
A drawing can use either named or color-dependent plot styles, but not both.
CONVERTPSTYLES converts a currently open drawing from color-dependent
plot styles to named plot styles, or from named plot styles to color-dependent plot styles, depending on which plot style method the drawing is
currently using.
For example, a drawing using color-dependent plot styles assigns plot properties to objects and layers by color. In other words, all objects with the same
color have the same plot properties. CONVERTPSTYLES converts the drawing
to use named plot styles that can be applied to objects or layers independent
of color assignment. In other words, all objects with the same color can have
different plot properties.
When you convert a drawing, CONVERTPSTYLES sets the PSTYLEMODE system
variable to the appropriate setting (1 = named, 0 = color-dependent).

CONVERTPSTYLES
Converting Drawings from Color-Dependent to
Named Plot Styles
A dialog box advises you to convert the drawing's plot style tables before converting the drawing. You can convert the color-dependent plot style tables
assigned to the drawing to named plot style tables using CONVERTCTB.
AutoCAD displays the Select File dialog box (a standard file selection dialog
box), where you select the named plot style table file to attach to the converted drawing.
CONVERTPSTYLES requires you to select a named plot style table that was converted using CONVERTCTB or created from a PC2 or PCP file. Normally you
should select the named plot style table that was converted from the colordependent plot style table that was assigned to the same drawing.
CONVERTPSTYLES attaches the selected named plot style table to model space
and to all layouts. Drawing layers are each assigned a named plot style (from
the converted plot style table) that has the same plot properties that their
color-dependent plot style had. Drawing objects that had the same colordependent plot style as their layer are assigned the named plot style
BYLAYER. Drawing objects that had a color-dependent plot style that was
different from their layer are assigned a named plot style that has the same
properties that their color-dependent plot style had.
After a drawing is converted to named plot styles, you can change the named
plot style table assignment or assign other named plot styles tables to model
space or layouts. You can also assign individual plot styles to drawing objects.
Converting Drawings from Named to ColorDependent Plot Styles
A dialog box advises you that the named plot styles attached to objects and
named plot style tables attached to model space and layouts will be detached.
After a drawing is converted to color-dependent plot styles, you can assign a
color-dependent plot style table. Plot styles will be applied by color.

of AutoCAD, is an advanced implementation of the Query Editor. You begin
a Link Select operation by creating an initial query or selection set of
graphical objects (set A), which can be operated on by an additional query or
selection set (set B). The results of the returned operation become the new
running selection set (set A), and you can apply additional queries or selection sets to further refine your running query.
In order to work with the Link Select dialog box, you must have a drawing
open that has a number of links already created. You can open this dialog box
using the following methods:

Second Extension Line Origin
By default, AutoCAD uses the first extension line of the base dimension as
the extension line origin for the baseline dimension. To override this default
behavior, explicitly select the base dimension; the extension line origin
becomes the extension line of the base dimension closest to the pick point
of the selection. When you select a second point, AutoCAD draws the baseline dimension and redisplays the Specify a Second Extension Line Origin
prompt. To end the command, press ESC . To select another linear, ordinate,
or angular dimension to use as the basis for the baseline dimension, press
ENTER .

DIMCONTINUE
Creates a linear, angular, or ordinate dimension from the second extension line of the
previous dimension or a selected dimension
DIMCONTINUE draws a series of related dimensions, such as several shorter
dimensions that add up to the total measurement. Continued dimensioning
is also known as chain dimensioning.
When you create linear continued dimensions, the first extension line is
suppressed and the placement of text and arrowheads might include a leader
line. These appear as overrides for the continued dimension (the DIMSE1
system variable is on, and the DIMTMOVE system variable is 1).
Dimension toolbar:

DIMDIAMETER
Creates diameter dimensions for circles and arcs
DIMDIAMETER draws different types of diameter dimensions depending on
the size of the circle or arc, the options set for the dimension style (see
DIMSTYLE), and the position of the cursor. The dimension style controls
center marks and centerlines. AutoCAD does not draw a center mark or a
centerline when a dimension line is drawn inside the arc or circle. AutoCAD
stores the setting for center marks and centerlines in the DIMCEN system
variable.
For horizontal dimension text, if the angle of the diameter line is greater than
15 degrees from horizontal and is outside the circle or arc, AutoCAD draws a
hook line one arrowhead long next to the dimension text, as shown in the
first two illustrations.
Different types of diameter dimensions
Dimension toolbar:
Dimension menu: Diameter
Command line: dimdiameter
Select arc or circle:
AutoCAD measures the diameter and displays the text with a diameter
symbol (∅) in front of it. The position of the cursor determines the location
of the dimension line. As you move the cursor, the dimension moves around

DIMSTYLE
Creates and modifies dimension styles
A dimension style is a saved set of dimension settings that determines the
appearance of the dimension. By creating dimension styles, you can set all
relevant dimensioning system variables and control the layout and appearance of any dimension.
Dimension styles can have multiple secondary styles with varying settings.
For example, within a dimension style, you can create a secondary style for
radius dimensions and another secondary style for angular dimensions.
AutoCAD uses the appropriate secondary style for the type of dimension you
create. If there are no differences in settings for a dimension type, the
primary dimension-style settings are used.

Create New Dimension Style Dialog Box
Names the new dimension style, sets the style on which to start the new one,
and indicates the dimension types to which you want the new style to apply.
New Style Name
Names the new style.
Start With
Sets a style to use as a basis for the new one. For the new
style, you change only the properties that differ from
the properties you start with.
Use For
Creates a style that applies only to specific dimension
types. For example, suppose the text color for the
STANDARD style is black, but you want the text to be
blue only for diameter dimensions. Under Start With,
select STANDARD, and under Use For, select Diameter.
New Style Name becomes unavailable because you are
defining a substyle of STANDARD. After you change the
text color to blue in the New Dimension Style dialog
box, Diameter is displayed as a substyle under
STANDARD in the Dimension Style Manager. Whenever
you use the STANDARD style for diameter dimensions,
the text is blue. When you use STANDARD for all other
dimension types, the text is black.
Continue
Displays the New Dimension Style dialog box, in which
you define the new style properties.
New, Modify, and Override Dimension Style
Dialog Boxes
Set properties for dimension styles. After you choose Continue in the Create

DVIEW
Defines parallel projection or perspective views
To help you view a model from any point in space, DVIEW uses a camera-target metaphor. The line of sight, or viewing direction, is the line between the
camera and the target.
DVIEW uses objects you select or a special block named DVIEWBLOCK to display a preview image. The preview image shows the changes you make in the
view. When you end the command, AutoCAD regenerates the drawing based
on the view you set.
Transparent ZOOM, DSVIEWER, PAN, and scroll bars are not available in

Toggle (Angle
From)
Switches between two angle input modes. Entering an
angle on the command line locks the cursor movement
so you see only the positions available for that angle.
Toggle unlocks the cursor movement for the angle, and
you can use the cursor to rotate the target.
Distance
Moves the camera in or out along the line of sight relative to the target. This
option turns on perspective viewing, which causes objects farther from the
camera to appear smaller than those closer to the camera. A special perspective icon replaces the coordinate system icon. AutoCAD prompts for the new
camera-to-target distance.
Specify new camera-target distance <current>: Enter a distance or press ENTER
A slider bar along the top of the drawing area is labeled from 0x to 16x,
with 1x representing the current distance. Moving the slider bar to the right
increases the distance between camera and target. Moving it to the left
decreases that distance. To turn off perspective viewing, choose the Off
option from the main DVIEW prompt.
If the target and camera points are close together, or if you specify a longfocal-length lens, you might see very little of your drawing when you specify
a new distance. If you see little or none of your drawing, try the maximum
scale value (16x) or enter a large distance. To magnify the drawing without
turning perspective viewing on, use the Zoom option of DVIEW (see page
338).

Points
Locates the camera and target points using X,Y,Z coordinates. You can use
XYZ point filters. You must specify these points in a nonperspective view. If
perspective viewing is on, AutoCAD turns it off while you specify new
camera and target locations, and then redisplays the preview image in
perspective view.
Specify target point <current>: Specify a point or press ENTER
To help you define a new line of sight, AutoCAD draws a rubber-band line
from the current camera position to the crosshairs. AutoCAD prompts you
for a new camera location.

1x representing the current scale. Moving the slider bar to the right increases
the scale. Moving it to the left decreases the scale.

DVIEW
If perspective viewing is on, Zoom adjusts the camera lens length, which
changes the field of view and causes more or less of the drawing to be visible
at a given camera and target distance. The default lens length is 50mm, simulating what you’d see with a 35mm camera and a 50mm lens. Increasing the
lens length is similar to switching to a telephoto lens. Decreasing the lens
length widens the field of view, as with a wide-angle lens.
Specify lens length <50.000mm>: Specify a value or press ENTER
A slider bar along the top of the drawing area is labeled from 0x to 16x, with
1x representing the current lens length. Moving the slider bar to the right
increases the lens length. Moving it to the left decreases the lens length.

Hide
Suppresses hidden lines on the selected objects to aid in visualization.
AutoCAD considers circles, solids, traces, regions, wide polyline segments,
3D faces, polygon meshes, and the extruded edges of objects with nonzero
thickness to be opaque surfaces that hide objects.This hidden line suppression is quicker than that performed by HIDE, but it can't be plotted.

ELEV
Sets elevation and extrusion thickness of new objects
The current elevation is the Z value that AutoCAD uses whenever it expects
a 3D point but receives only X and Y values. AutoCAD maintains separate
current elevations in model space and paper space. Specifying an elevation
setting in one viewport makes that elevation current in all viewports regardless of whether viewports are set up to retain their own user coordinate
systems (UCSs). AutoCAD resets the elevation to 0.0 whenever you change
the coordinate system.
Command line: elev (or 'elev for transparent use)
Specify new default elevation <current>: Specify a distance or press ENTER
Specify new default thickness <current>: Specify a distance or press ENTER
The thickness sets the distance to which AutoCAD extrudes a 2D object
above or below its elevation. A positive value extrudes along the positive Z
axis; a negative value extrudes along the negative Z axis.

Lightweight
Polyline
Discards any associated width or tangent information.
For wide polylines, AutoCAD places the resulting lines
and arcs along the center of the polyline.
3D Polyline
Explodes into line segments. Any linetype assigned to
the 3D polyline is applied to each resulting line
segment.
3D Solid
Explodes planar surfaces into regions. Nonplanar
surfaces explode into bodies.
Arc
If within a nonuniformly scaled block, explodes into
elliptical arcs.
Block
Removes one grouping level at a time. If a block
contains a polyline or a nested block, exploding the
block exposes the polyline or nested block object,
which must then be exploded to expose its individual
objects.
after EXPLODE
Blocks with equal X, Y, and Z scales explode into their
component objects. Blocks with unequal X, Y, and Z
scales (nonuniformly scaled blocks) might explode into
unexpected objects.
When nonuniformly scaled blocks contain objects that
cannot be exploded, they are collected into an
anonymous block (named with a “*E” prefix) and
referenced with the nonuniform scaling. If all the
objects in such a block cannot be exploded, the selected
block reference will not be exploded. Body, 3D Solid,
and Region entities in a nonuniformly scaled block
cannot be exploded.
Exploding a block that contains attributes deletes the
attribute values and redisplays the attribute definitions.
Blocks inserted with MINSERT and external references
(xrefs) and their dependent blocks cannot be exploded.

369
Body
Explodes into a single-surface body (nonplanar
surfaces), regions, or curves.
Circle
If within a nonuniformly scaled block, explodes into
ellipses.
Leaders
Explodes into lines, splines, solids (arrow heads), block
inserts (arrow heads, annotation blocks), multiline text,
or tolerance objects, depending on the leader.
Multiline text
Explodes into text objects.
Multiline
Explodes into lines and arcs.
Polyface Mesh
Explodes one-vertex meshes into a point object. Twovertex meshes explode into a line. Three-vertex meshes
explode into 3D faces.

371
If you select a 2D polyline as a boundary object, AutoCAD ignores its width
and extends objects to the centerline of the polyline. You can use only the
single, crossing, fence, and implied selection options to select boundaries
that include blocks.
If you extend a tapered polyline segment, AutoCAD corrects the width of the
extended end to continue its original taper to the new endpoint. If this
causes the segment to have a negative ending width, the ending width
becomes zero.

EXTRUDE
Creates unique solid primitives by extruding existing two-dimensional objects
With EXTRUDE, you can create solids by extruding (adding thickness to)
selected objects. You can extrude an object along a path, or you can specify
a height value and a tapered angle.
Use EXTRUDE to create a solid from a common profile of an object, such as a
gear or sprocket. EXTRUDE is particularly useful for objects that contain
fillets, chamfers, and other details that might otherwise be difficult to reproduce except in a profile. If you create a profile using lines or arcs, use the Join
option of PEDIT to convert them to a single polyline object or make them into
a region before you use EXTRUDE.

EXTRUDE
Object Selection
select object
Specifies the objects to extrude. You can extrude planar 3D faces, closed
polylines, polygons, circles, ellipses, closed splines, donuts, and regions. You
cannot extrude objects contained within a block or polylines that have crossing or self-intersecting segments.
A polyline must contain at least 3 but not more than 500 vertices. If a
selected polyline has width, AutoCAD ignores the width and extrudes from
the center of the polyline path. If a selected object has thickness, AutoCAD
ignores the thickness.
Height of Extrusion
Extrudes the objects along the positive Z axis of the object’s coordinate
system if you enter a positive value. If you enter a negative value, AutoCAD
extrudes the objects along the negative Z axis.
height
Specify angle of taper for extrusion <0>:
degrees or press ENTER
Specify an angle between –90 and +90
Positive angles taper in from the base object. Negative angles taper out. The
default angle, 0, extrudes a 2D object perpendicular to its 2D plane. AutoCAD
tapers all objects and loops in the selection set to the same value. Tapered
extrusions are possible only with loops that are continuous at the vertices.
taper
angle
Specifying a large taper angle or a long extrusion height can cause the object
or portions of the object to taper to a point before reaching the extrusion
height.
AutoCAD always extrudes individual loops of the region to the same height.
path
profile
When an arc is part of a tapered extrusion, the angle of the arc remains constant, and the radius of the arc changes. On a straight extrusion, each arc
results in a single cylindrical face. Whenever possible, EXTRUDE uses the
taper angle as the angle by which it slants faces from the Z axis.
Path
Selects the extrusion path based on a specified object. AutoCAD extrudes the
profiles of the selected object along the chosen path to create solids.
Select extrusion path:
Use an object selection method
Lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines can be paths.
The path should not lie on the same plane as the profile, nor should it have
areas of high curvature.
EXTRUDE
|
375
The extruded solid starts from the plane of the profile and ends on a plane
perpendicular to the path at the path’s endpoint. One of the endpoints of the
path should be on the plane of the profile; otherwise, AutoCAD moves the
path to the center of the profiles.
If the path is a spline, it should be perpendicular to the plane of the profile
at one of the endpoints of the path. Otherwise, AutoCAD rotates the profile
to be perpendicular to the spline path. If one of the endpoints of the spline
is on the plane of the profile, AutoCAD rotates the profile about the point;
otherwise, AutoCAD moves the spline path to the center of the profile and
rotates the profiles about its center.
If the path contains segments that are not tangent, AutoCAD extrudes the
object along each segment and then miters the joint along the plane bisecting the angle formed by the segments. If the path is closed, the profile should
lie on the miter plane. This allows the start and end sections of the solid to
match up. If the profile is not on the miter plane, AutoCAD rotates it until it
is on the miter plane.
AutoCAD extrudes profiles with multiple loops so that all the loops appear
on the same plane at the end section of the extruded solid.

FILL
Controls the filling of objects such as hatches, two-dimensional solids, and wide polylines
Some displays and plotters take a long time to fill the interior of objects; turn
off Fill mode to improve performance. Objects affected by FILL include
hatches, two-dimensional solids, wide polylines, AutoCADmultilines and
traces.
Command line: fill (or 'fill for transparent use)
Enter mode [ON/OFF] <current>: Enter on or off, or press ENTER
Fill mode on
Fill mode off
On
Turns on Fill mode. For the filling of a 3D object to be
visible, its extrusion direction must be parallel to the
current viewing direction, and hidden lines must not be
suppressed.
Off
Turns off Fill mode. Only the outlines of objects are
displayed and plotted. Changing Fill mode affects
existing objects after the drawing is regenerated. The
display of lineweights is not affected by the Fill mode
setting.

FILLET
Rounds and fillets the edges of objects
FILLET rounds the edges of two arcs, circles, elliptical arcs, lines, polylines,
rays, splines, or xlines with an arc of a specified radius. FILLET also rounds the
edges of 3D solids.
before FILLET
after FILLET
If the TRIMMODE system variable is set to 1, FILLET trims the intersecting lines
to the endpoints of the fillet arc. If the selected lines do not intersect,
AutoCAD® extends or trims them so that they do.
If both objects you want to fillet are on the same layer, AutoCAD creates the
fillet line on that layer. Otherwise, AutoCAD creates the fillet line on the
current layer. The same is true for the fillet color, lineweight, and linetype.
FILL
|
377
You can fillet line segments of a polyline that are adjacent, nonadjacent,
intersecting, or separated by one segment. If they are nonadjacent, the
polyline segments are extended to accommodate the fillet. If they are intersecting, the polyline segments are trimmed to accommodate the fillet. To
create a fillet, the polyline segments must converge within the drawing limits
when limits checking is on.
The result is a single polyline that includes the fillet as an arc segment. All
the properties of this new polyline, such as its layer, color, and linetype, are
inherited from the first polyline selected.
Note Filleting an associative hatch whose boundary was defined from line segments removes hatch associativity. If the boundary was defined from a polyline,
associativity is maintained.

If you select lines, arcs, or polylines, AutoCAD extends them until they intersect or trims them at the intersection. You can fillet two lines with different
extrusion directions only if the Z values of the endpoints of both lines are
equal in the current user coordinate system (UCS).
If the selected objects are straight line segments of a 2D polyline, they can be
adjacent or separated by one other segment. If they are separated by another
polyline segment, FILLET deletes the segment that separates them and
replaces it with the fillet.
More than one fillet can exist between arcs and circles. AutoCAD chooses the
fillet with endpoints closest to the points you select.

HATCH
Fills an area with a nonassociative hatch pattern
A nonassociative hatch is not updated when its boundaries are modified. A
hatch boundary consists of an object or objects that completely enclose an
area. If the boundary is made up of multiple objects, their endpoints must
coincide for the hatch to be created properly. You can also fill an area that
does not have a closed boundary, by defining a polyline hatch boundary
with the Direct Hatch option.
Unless you specify otherwise, HATCH combines the lines that make up the
hatch into a block.
Hatches are stored as single hatch objects, which can reduce the amount of
disk space a drawing occupies and can also reduce regeneration time.
Note By default, AutoCAD won’t create a hatch pattern that consists of over
10,000 segments. The limit is set by the MaxHatch setting in the registry. To
reset the limit to 50,000, for example, enter (setenv "MaxHatch" "50000") at
the Command prompt. The limit can be reset to any value between 100 and
10,000,000.
Command line: hatch

HATCH
Hatch Style Codes
Hatching styles control the method that AutoCAD uses to hatch internal
boundary objects. Specify a hatch style by following the pattern name with
a comma and the hatch style code. You can list the hatch style codes by following the pattern name with a comma (,) and a question mark (?).
For example, to hatch only the outermost area of a structure with several
internal boundaries using the MUDST pattern, enter mudst,o at the Pattern
prompt. To opt for a user-defined pattern and use the Ignore style, enter u,i.
AutoCAD stores the style by adding the comma and code to the pattern
name in the HPNAME system variable.
n (Normal)
Hatches inward from the outermost area boundary. If
AutoCAD encounters an internal boundary, it turns off
hatching until it encounters another boundary. Thus,
areas separated from the outside of the hatched area by
an odd number of boundaries are hatched, and areas
separated by an even number of boundaries are not.
o (Outer)
Hatches outermost areas only. This style hatches
inward from the area boundary, but it turns off
hatching if it encounters an internal boundary and
does not turn it back on again. Because this process
starts from both ends of each hatch line, this style
hatches only the outermost area of the structure and
leaves the internal structure blank.
i (Ignore)
Ignores all internal objects and hatches through them.
? (List Styles)
Lists hatch styles.
Note Hatching concave curves using the Outer and
Ignore styles can cause discrepancies.

HIDE
Regenerates a three-dimensional model with hidden lines suppressed
When you use VPOINT, DVIEW, or VIEW to create a 3D view of your drawing,
AutoCAD produces a wireframe display in the current viewport. All lines are
present, including those hidden by other objects. HIDE eliminates the hidden
lines from the screen.
Render toolbar:
View menu: Hide
Command line: hide
HIDE considers the following to be opaque surfaces that hide objects: circles,
solids, traces, text, regions, wide polyline segments, 3D faces, polygon
meshes, and the extruded edges of objects with nonzero thickness.
If they are extruded, AutoCAD treats circles, solids, traces, and wide polyline
segments as solid objects with top and bottom faces. You cannot use HIDE on
objects whose layers have been frozen; however, you can use HIDE on objects
whose layers have been turned off.
In order to hide text created with DTEXT, MTEXT, or TEXT, the HIDETEXT
system variable must be set to 1 or the text must be assigned a thickness
value.
When using the HIDE command, if the INTERSECTIONDISPLAY system variable
is on, face-to-face intersections of 3D surfaces are displayed as polylines.

If the DISPSILH system variable is on, HIDE displays 3D solid objects with
silhouette edges only. It won’t show the internal edges produced by objects
that have facets.
If the HIDETEXT system variable is off, HIDE ignores text objects when producing the hidden view. Text objects are always displayed regardless of whether
they are obscured by other objects, and objects obscured by text objects are
unaffected.
See Also
See “Hide Lines or Shade 3D Objects” in the User’s Guide.
Commands
DVIEW defines parallel projection or perspective views
on the screen as you change views. VIEW saves and
restores named views. VPOINT sets the viewing direc-
tion for a 3D visualization of the current drawing.

Image Manager
Lists all the image files attached to the current drawing. You can view the
parameters and details for selected images. You can attach new image files
and detach, locate, reload, and unload attached images.
List of Images
Displays the names of all image files attached to the drawing. You can use F3
and F4 to toggle between list view and tree view.
List View
Lists the image definitions attached to the drawing.
Each image name appears only once regardless of how
many times the image is attached (inserted). You can
sort the list of images by name, status (loaded,
unloaded, or not found), type (TIFF, for example), date,
size, or the saved path and file name. By default,
AutoCAD displays the list alphabetically by image
name.

To change the width of the column, drag the line
between the column headings to the right or left.
AutoCAD saves and restores the settings when you
reopen the dialog box.
To change an image name, select it and then click it
again, or select it and then press F2 . You cannot edit
names of images that reside in external references
(xrefs). Image names can include up to 255
characters and can contain letters, digits, spaces, and
any special characters not used by
Microsoft® Windows® or AutoCAD. The image
name can be identical to the file name, but changing
the image name does not change the file name.
Displays all the image definitions and the levels of
nesting of images within xrefs. The top level of the tree
view shows images that you attached directly to the
drawing, images nested in block references, and the
names of externally referenced drawings containing
images. The names of the images attached to the
externally referenced drawings appear nested within
the drawing at the next tree level. To insert a copy of an
already attached image, select it, and then choose
Attach.
Tree view lists the image names only (not file names)
and lists the image name just once, regardless of how
many times the image is attached (insert).
You can edit an image name by selecting it and then
clicking it again, or by selecting it and then pressing F2 .
However, you cannot select more than one image at a
time.
Attach
Displays the Select Image File dialog box. See IMAGEATTACH. When you
unload and then reload an image, AutoCAD draws that image on top. For
more information about how to control where and how AutoCAD places the
image, see SORTENTS and DRAWORDER. Images remain loaded or unloaded
from one drawing session to the next.
Detach
Removes the selected image definitions from the drawing database and erases
all the associated image objects from the drawing and from the display.
IMAGE
|
425
Reload
Loads the most recent version of an image or reloads an image that was
previously unloaded. Reloading does not control whether the image is
displayed, but it ensures display of the most current image.
Unload
Unloads image data from working memory without erasing the image
objects from the drawing. It is recommended that you unload images no
longer needed for editing to improve performance. An unloaded image
cannot be displayed or plotted.
You can selectively load and unload individual images from a working list of
images associated with the drawing file.
Details
Opens the Image File Details dialog box, which displays the image name,
saved path, active path, file creation date and time, file size and type, color
system, color depth, width and height in pixels, resolution, default size in
units, and a preview image.
Image Found At
Shows the path of the selected image. If you select multiple images, this field
remains blank. The path shown is the actual path where the image resides. If
AutoCAD does not find the file at the path in the Saved Path column,
AutoCAD first searches the standard AutoCAD search path for the image’s
saved path. (See “Specify Search Paths, File Names, and File Locations” in the
User’s Guide.) If AutoCAD cannot locate the drawing (for example, if you have
moved the file to a different directory than the one that was saved with the
image), it removes relative or absolute path information from the name (for
example, \images\tree.tga or c:\my project\images\tree.tga become tree.tga)
and searches the paths defined in the Project Files Search Path in the Options

Opens the Select Image File dialog box (a standard file selection dialog box).
The path you select appears under Image Found At. See IMAGEATTACH.
Save Path
Stores the new path information. Press ESC while editing the path to restore
the old path. If AutoCAD cannot find the referenced image in the new path,
the image’s status changes to Not Found. If you do not choose Save Path after
editing the path, AutoCAD uses the original image path the next time you
load the drawing.

IMAGE
AutoCAD assigns the file name without the extension as the image name.
Image names can include up to 255 characters and contain letters, digits,
spaces, and any special characters not used by Microsoft Windows or
AutoCAD. If the file name is not a valid name for a nongraphical object, the
Substitute Image Name dialog box is displayed. AutoCAD automatically generates a valid image name from the file name and appends an underscore and
number to the name, changing the number as necessary to avoid duplicate
image names.
Image file name_1 created from file file name.bmp
If a definition with the same name and path exists in the drawing, AutoCAD
displays the following prompts and inserts the image as a copy:
Image file name has already been loaded.
Use IMAGE Reload to update its definition.
Specify insertion point <0,0>: Specify an insertion point
Base image size: Width: current width, Height: current height, current unit
Specify scale factor: Enter a value or press ENTER
Specify rotation angle <0>: Enter a value or press ENTER
If the FILEDIA system variable is set to 0, AutoCAD displays the following
prompt instead of the dialog box:
Enter image file name to attach <last>: Enter an image name
The last image name attached to the drawing during the current session is the
default. To avoid errors when entering an image name, it is recommended
that you specify both the image name and the file name as follows:
imagename=path name\long file name.bmp
or
imagename="path name\long file name.bmp"
If you enter a valid image name without a file extension, AutoCAD searches
for the file in this order: first, an existing image definition in the drawing,
and second, an image file in the folders in order of the search path. AutoCAD
searches for all the image files with the specified name, regardless of extension, and uses the first name found. If no image name or image file is found,
AutoCAD displays the message “Image Not Found” and repeats the prompt.
IMAGE

429
To specify a long file name that does not conform to AutoCAD naming rules,
enter the name as follows:
"imagename=filename"
You can use a dialog box to search for image files but still enter the
imagename=filename convention on the command line. Enter a tilde (~) at the
Enter Image File Name to Attach prompt. If you press ESC after the dialog box
opens, AutoCAD redisplays the Enter Image Name prompt.

IMAGEFRAME
IMAGEQUALITY
Controls the display quality of images
The quality setting affects display performance; high-quality images take
longer to display. Changing the setting updates the display immediately
without causing a regeneration of the drawing. AutoCAD always plots images
using a high-quality display.
Reference toolbar:
Modify menu: Object ➤ Image ➤ Quality
Command line: imagequality
Enter image quality setting [High/Draft] <current>: Enter an option or press
ENTER
High
Produces a high-quality display of the image. AutoCAD
displays the image more slowly than a draft-quality
image.
Draft
Produces a lower-quality display of the image.
AutoCAD displays the image more quickly than a highquality image.

You can control block insertion behavior in response to the Enter Block
Name prompt by following the listed examples.
■
■
Inserting Exploded Blocks: Preceding the name of the block with an asterisk
(*) explodes the block and inserts the individual parts of it. The block
definition is not added to the drawing.
Updating a Block Path: If you enter a block name without a path name,
AutoCAD first searches the current drawing data for an existing block
definition by that name. If no such block definition exists in the current
drawing, AutoCAD searches the library path for a file of the same name. If
AutoCAD finds such a file, it uses the file name for the block name upon
insertion of the block definition. AutoCAD uses the same block definition
for subsequent insertions of that block. You can replace an existing block
definition with an external file by entering the following at the Enter
Block Name prompt:
block name=file name
■
Updating a Block Definition: If you make changes to a block file that is
inserted in your drawing and you want to change the existing block
definition without creating a new block insertion, enter the following at
the Specify Insertion Point prompt (following the Enter Block Name
prompt):
block name=
If you enter = after the block name, AutoCAD displays the following
prompt:
Block "current" already exists. Redefine it? [Yes/No] <No>: Enter y, enter n, or
press ENTER
If you choose to redefine the block, AutoCAD replaces the existing block
definition with the new block definition. AutoCAD regenerates the drawing and the new definition is applied to all existing insertions of it. Press
ESC when AutoCAD prompts you for the insertion point if you do not
want AutoCAD to insert a new block into the drawing.

INSERTOBJ
Inserts a linked or embedded object
When you insert an object into an AutoCAD drawing from an application
that supports OLE, the object can maintain a connection with its source file.
See “Link and Embed Data (OLE)” in the User’s Guide.
A linked object remains associated with its source file. When you edit a
linked object in AutoCAD, the source file changes. When you edit the object
in the source file, the linked object in AutoCAD changes.
An embedded object is not associated with its source file. You edit the embedded data in the AutoCAD drawing using the source application; the source
file does not change.
Linked or embedded objects are displayed in AutoCAD and can be printed or
plotted using Windows system drivers.

The selection set can contain regions and solids that lie in any number of
arbitrary planes. AutoCAD divides the selection set into subsets and tests for
intersections within each subset. The first subset contains all the solids in the
selection set. The second subset contains the first selected region and all subsequent coplanar regions. The third subset contains the next region that is
not coplanar with the first region and all subsequent coplanar regions, and
so on until all regions belong to a subset.

sample layers
If you enter -layer at the Command prompt, LAYER displays prompts on the
command line (see page 469).
Layer Properties Manager
Makes a layer current, adds new layers, deletes layers, and renames layers.
You can assign properties to layers, turn layers on and off, freeze and thaw
layers globally or by viewport, lock and unlock layers, set plot styles for
layers, and turn plotting on and off for layers. You can filter the layer names
displayed in the Layer Properties Manager, and you can save and restore layer
states and properties settings.
LAYER
|
457
Named Layer Filters
Determines which layers to display in the list of layers. You can filter layers
based on whether they’re xref-dependent, or whether they contain objects.
You can also filter layers based on name, visibility, color, linetype, lineweight,
plot style name, whether they are plotted, or whether they are frozen in the
current viewport or in new viewports.
458
|
[...] Button
Displays the Named Layer Filters dialog box (see page
464).
Invert Filter
Displays layers based on the opposites of the criteria in
a named layer filter. Layers that fit the inverse criteria
are displayed in the layer name list.
Apply to Layers
Toolbar
Displays in the Layers toolbar only layers that match
the current filter. The layer list tooltip on the Layers
toolbar displays the filter status of layers in the drawing.
(To display the layer list tooltip, position the pointing
device over the layer list on the Layers toolbar.)
LAYER
New
Creates a new layer. After you choose New, the list displays a layer named
LAYER1. You can edit this layer immediately. To create multiple layers more
quickly, you can select a layer name for editing and enter multiple layer
names separated by commas.
If you create a new layer, the new layer inherits the properties of the currently
selected layer in the layer list (Color, On/Off state, and so on). To create layers
with default settings, make sure that there are no selected layers in the list or
that you select a layer with default settings before beginning layer creation.
Current
Sets the selected layer as the current layer. The CLAYER system variable stores
the layer name.
Delete
Deletes selected layers from the drawing file definition. You can delete only
unreferenced layers. Referenced layers include layers 0 and DEFPOINTS, layers
containing objects (including objects in block definitions), the current layer,
and xref-dependent layers. Layers that don’t contain objects (including
objects in block definitions), are not current, and are not xref-dependent can
be deleted by using the PURGE command.
Warning! Be careful about deleting layers if you are working on a drawing in
a shared project or one based on a set of layering standards.
Show/Hide Details
Controls whether the Details section (see page 461) is displayed in the Layer
Properties Manager.
Save State
Displays the Save Layer States dialog box (see page 466), in which you save
layer state and layer properties settings of all layers in a drawing. You can
choose which layer states and properties that you want to preserve. You save
a layer state by assigning it a name.
If one or more of these settings are cleared, the Layer Properties Manager does
not restore those settings.
Any layer states saved in a drawing that is inserted in your current drawing
as a block are also added to the current drawing.
The saved layer states of referenced drawings (xrefs) are not accessible from
the current drawing.
LAYER
|
459
If you use WBLOCK to create a new drawing from the current drawing, saved
layer states are preserved only if you specify Entire Drawing as the source in
the Write Block dialog box (equivalent to -wblock /* on the command line).
These saved layer states will refer only to layers that contain objects.
State Manager
Displays the Layer States Manager (see page 467), in which you can manage
named layer states.
List of Layers
Displays layers and their properties. To modify a property, click its icon. To
quickly select all layers, right-click and use the shortcut menu.
Names
Displays the names of the layers. You can select a name,
and then click and enter a new name.
On/Off
Turns layers on and off. When a layer is on, it is visible
and available for plotting. When a layer is off, it is
invisible and not plotted, even if Plot is on.
Freeze/Thaw in
All Viewports
Freezes selected layers in all viewports. You can freeze
layers to speed up ZOOM, PAN, and many other
operations; improve object selection performance; and
reduce regeneration time for complex drawings.
AutoCAD does not display, plot, hide, render, or
regenerate objects on frozen layers.
Freeze the layers you want to be invisible for long
periods. When you thaw a frozen layer, AutoCAD
regenerates and displays the objects on that layer. If you
plan to switch between visible and invisible states
frequently, use the On/Off setting. You can freeze layers
in all viewports, in the current layout viewport, or in
new layout viewports as they are created.
460
|
Lock/Unlock
Locks and unlocks the layers. You cannot edit objects
on a locked layer. Locking a layer is useful if you want
to view information on a layer for reference but do not
want to edit objects on that layer.
Color
Changes the color associated with the selected layers.
Clicking the color name displays the Select Color dialog
box (see page 169).
Linetype
Changes the linetype associated with the selected
layers. Clicking any linetype name displays the Select
Linetype dialog box (see page 468).
LAYER
Lineweight
Changes the lineweight associated with the selected
layers. Clicking any lineweight name displays the
Lineweight dialog box (see page 468).
Plot Style
Changes the plot style associated with the selected
layers. If you are working with color-dependent plot
styles (the PSTYLEPOLICY system variable is set to 1), you
cannot change the plot style associated with a layer.
Clicking any plot style displays the Select Plot Style
dialog box (see page 746).
Plot/Don’t Plot
Controls whether the selected layers are plotted. If you
turn off plotting for a layer, the objects on that layer are
still displayed. Turning off plotting for a layer affects
only visible layers in the drawing (layers that are on and
thawed). If a layer is set to plot but is currently frozen
or off in the drawing, AutoCAD does not plot the layer.
Turning off plotting for layers containing reference
information such as construction lines can be useful.
Current VP Freeze
(available only
from a layout tab)
Freezes selected layers in the current layout viewport.
You can freeze or thaw layers in the current viewport
without affecting layer visibility in other viewports.
Frozen layers are invisible; they are not regenerated or
plotted. Thawing restores the layer's visibility.
New VP Freeze
(available only
from a layout tab)
Freezes selected layers in new layout viewports. For
example, freezing the DIMENSIONS layer in all new
viewports restricts the display of dimensions on that
layer in any newly created layout viewports but does
not affect the DIMENSIONS layer in already existing
viewports. If you then create a viewport that requires
dimensions, you can override the default setting by
changing the current viewport setting.
Details
Displays an extension of the Layer Properties Manager with alternative access
to properties and additional options.

Name
Displays the selected layer name, which can be edited.
The name can include letters, numbers, blank spaces,
and any special character not used by Microsoft®
Windows® or AutoCAD for other purposes.
Color
Displays a list of colors available to apply to the selected
layers. To assign a color other than those displayed in
the list, choose Select Color. To define the color of
layers, you can select from the 255 AutoCAD Color
Index (ACI) colors, true colors, and color book colors.
Lineweight
Displays a list of fixed lineweights available to apply to
the selected layers including DEFAULT. You can also
customize lineweights to plot at whatever width you
want by using the Plot Style Table Editor.
Linetype
Displays linetypes available to apply to the selected
layers. To load additional linetypes, choose a linetype
in the list of layers to display the Select Linetype dialog
box (see page 468), and then choose Load.
LAYER
Plot Style
Displays a list of plot styles available to apply to the
selected layers. If you are working with colordependent plot styles (the PSTYLEPOLICY system
variable is set to 1), you cannot change the plot style
associated with a layer. The default plot style is Normal.
Off for Display
Turns selected layers on or off. Turned-off layers
regenerate with the drawing but are not displayed or
plotted. You can turn layers off rather than freeze layers
if you frequently change layers from visible to invisible.
By turning layers off to make their objects invisible, you
avoid regenerating the drawing every time you restore
visibility. When you turn a layer on that has been
turned off, the objects are only redrawn on that layer.
Lock for Editing
Prevents objects on selected layers from being edited.
Locking layers is useful when you want to edit objects
that are associated with particular layers but also want
to view objects on other layers. Although you cannot
edit objects on a locked layer, they are still visible if the
layer is on and thawed. You can make a locked layer
current, and you can add objects to it.
Do Not Plot
Prevents the selected layers from being plotted. This
option affects only visible layers in the drawing (layers
that are on or thawed). If a layer is set to plot, but is
currently frozen or off in the drawing, the layer is not
plotted. It can be useful to turn off plotting for a layer
that contains reference information. You can view the
reference information while you work, but you can turn
off plotting for that layer to ensure that the reference
information does not appear in the plotted drawing.
Freeze in All
Viewports
Freezes selected layers in all viewports. You can freeze
layers to speed up ZOOM, PAN, and many other
operations; improve object selection performance; and
reduce regeneration time for complex drawings.
AutoCAD does not display, plot, hide, render, or
regenerate objects on frozen layers.
LAYER
|
463
Freeze the layers you want to be invisible for long
periods. When you thaw a frozen layer, AutoCAD
regenerates and displays the objects on that layer. If you
plan to switch between visible and invisible states
frequently, use the On/Off setting. You can freeze layers
in all viewports, in the current layout viewport, or in
new layout viewports as they are created.
Freeze in Current
Viewport
Freezes selected layers in the current layout viewport.
You can freeze or thaw layers in the current layout
viewport without affecting layer visibility in other
viewports. Frozen layers are invisible; they are not
regenerated or plotted. This feature is useful, for
example, if you want to create an annotation layer that
is visible only in a particular viewport. Thawing restores
the layer’s visibility. This option is available only when
you are working on a layout.
Freeze in New
Viewports
Freezes selected layers in new layout viewports. For
example, freezing the DIMENSIONS layer in all new
viewports restricts the display of dimensions on that
layer in any newly created layout viewports but does
not affect the DIMENSIONS layer in viewports that
already exist. If you then create a viewport that requires
dimensions, you can override the default setting by
thawing the layer in that viewport. This option is
available only when you are working on a layout.

LEADER
Creates a line that connects annotation to a feature
A leader line is an object that can be composed of an arrowhead attached to
splines or straight line segments. In some cases, a short horizontal line, called
a hook line, dogleg, or landing, connects text and feature control frames to
the leader line. If associative dimensioning is turned on with DIMASSOC, the
leader start point can be associated with a location on an object. If the object
is relocated, the arrowhead remains attached to the object and the leader line
stretches, but the text or feature control frame remains in place.
You can use various dimensioning system variables to format the leader line,
such as placing the text above the hook line with DIMTAD.
LEADER creates complex leader lines that can be made up of more than two
line segments. DIMDIAMETER and DIMRADIUS create simple automatic leader
lines with two line segments for circles and arcs.
Command line: leader
Specify leader start point:
Specify next point:
AutoCAD draws a leader line segment to the point specified and continues to
prompt for points and options.
Specify next point or [Annotation/Format/Undo] <Annotation>: Specify a point,
enter an option, or press ENTER
Point Specification
Draws a leader line segment to the point specified and continues to prompt
you for points and options.
Specify next point or [Annotation/Format/Undo] <Annotation>: Specify a point,
enter an option, or press ENTER

LEADER
Annotation
Inserts an annotation at the end of the leader line. The annotation can be
single or multiple lines of text, a feature control frame containing geometric
tolerances, or a block.
Enter first line of annotation text or <options>:
Enter text or press ENTER
If you enter text at the Annotation prompt, AutoCAD places the text at the
end of the leader line. AutoCAD prompts you for additional lines of text until
you end the command by pressing ENTER twice.
If you press ENTER at the Annotation prompt without entering text first,
AutoCAD displays the following prompt:
Enter an annotation option [Tolerance/Copy/Block/None/Mtext] <Mtext>:
Enter an option or press ENTER
Tolerance
Creates a feature control frame containing geometric
tolerances using the Geometric Tolerance dialog boxes
(see TOLERANCE).
You can create datum indicators and basic dimension
notation in these dialog boxes. After you specify the
geometric tolerance, LEADER ends.
Copy
Copies text, a multiline text object, a feature control
frame with geometric tolerances, or a block and
connects the copy to the end of the leader line. The
copy is associated with the leader line, meaning that if
the end of the leader line moves, the copied object
moves with it. The display of the hook line depends on
the object copied.
Select an object to copy:
AutoCAD places the object and ends LEADER. The value
of the current text gap (see DIMSTYLE or the DIMGAP
system variable) determines where AutoCAD inserts the
text and multiline text objects. AutoCAD attaches any
blocks or feature control frames with geometric
tolerances to the end of the leader line.
LEADER
|
483
Block
Inserts a block at the end of the leader line. AutoCAD
uses the same prompts as the INSERT command. The
block reference is inserted at an offset from the end of
the leader line and is associated to the leader line,
meaning that if the end of the leader line moves, the
block moves with it. No hook line is displayed.
Enter block name or [?]: Enter a block name or enter ? to
list all blocks in the drawing
None
Ends the command without adding any annotation to
the leader line.
Mtext
Creates text using the Multiline Text Editor (see page
577) when you specify an insertion point and a second
point for the text boundary.
Enter the characters for the text. Enclose format strings
for prefixes and suffixes in angle brackets (< >). Enclose
format strings for alternate units in square brackets ([ ]).
For more information about adding a prefix or suffix,
see “Control the Display of Dimension Units” in the
User’s Guide.
The units settings and the current text style determine
how AutoCAD displays the text. AutoCAD vertically
centers the multiline text and horizontally aligns it
according to the X axis direction of the last two vertices
of the leader line. AutoCAD offsets the multiline text
from the hook line by the distance specified under
Offset from Dim Line on the Text tab of the New,
Modify, or Override Dimension Style dialog box (see
page 288). If the offset specified is negative, AutoCAD
encloses the multiline text in a box as a basic
dimension.
After you specify the text, LEADER ends.
Format
Controls the way AutoCAD draws the leader and whether it has an
arrowhead.
Enter leader format option [Spline/STraight/Arrow/None] <Exit>: Enter an
option or press ENTER to return to the previous prompt
After each option, AutoCAD returns you to the Specify Next Point prompt.

The linetype you enter becomes the current linetype.
AutoCAD draws all new objects with this linetype,
regardless of the current layer. If the linetype you
request is not loaded, AutoCAD searches for its
definition in the acad.lin file. If the linetype is neither
loaded nor in acad.lin, AutoCAD displays a message and
returns you to the Command prompt.
Enter ? to list all loaded linetype names. If you enter
bylayer, new objects inherit the linetype associated
with the layer on which the object is drawn. If you
enter byblock, new objects are drawn using the
CONTINUOUS linetype until they are grouped into a
block. Whenever you insert that block, the objects
inherit the linetype of the block.

System Variables
CELTSCALE sets the current object linetype scaling fac-
tor. This sets the linetype scaling for new objects relative to the LTSCALE setting. A line created with CELTSCALE=2 in a drawing with LTSCALE set to 0.5 would
appear the same as a line created with CELTSCALE=1 in
a drawing with LTSCALE=1. LTSCALE stores the global
linetype scale factor. PSLTSCALE controls paper space
linetype scaling.
LIST
Displays database information for selected objects
Inquiry toolbar:
Tools menu: Inquiry ➤ List
Command line: list
Select objects:
Use an object selection method
AutoCAD lists the object type, object layer, and X,Y,Z position relative to the
current user coordinate system (UCS) and whether the object is in model
space or paper space.
LIST reports color, linetype, and lineweight information if these items are not
set to BYLAYER. The thickness of an object is displayed if it is nonzero. Z coordinate information defines the elevation. If the extrusion direction of the
entry differs from the Z axis (0,0,1) of the current UCS, LIST also reports the
extrusion direction in UCS coordinates.
LIST reports additional information related to the specific object selected.

LSEDIT
Edits a landscape object
A landscape object is an extended-entity object with a bitmap image mapped
onto it. You can manipulate the object directly in the drawing as well as in
the Landscape New dialog box. The geometry of the object depends on
whether you choose one or two faces for it and whether it is view aligned.
You make these choices according to your rendering requirements.
Each landscape object has grips at the base, top, and each corner. Use the base
grip to move the object, the top grips to adjust its height, and the bottom
corner grips to scale it and, if it’s not view aligned, rotate it. You can use all
standard AutoCAD grip editing modes for stretching, scaling, and rotating
landscape objects.

LSLIB
Default Geometry
Specifies the geometry and alignment of the object. The geometry of an
object depends on its number of faces and alignment. A single-face viewaligned object appears in the drawing as a triangle. You cannot use grips to
rotate it. A single-face fixed object appears as a rectangle that you can rotate
with grips. This type of object also displays its name either forward or backward to indicate its orientation to the camera, which is helpful for signs. A
crossing-face object always appears as two triangles intersecting at right
angles. When view-aligned, they face the camera at 45-degree angles and you
can’t change their rotation. When the object is fixed, you can change its
rotation.
Single Face/
Crossing Faces
Specifies a single-face object or a crossing-face object. A
single-face object is faster to render but not quite as
realistic as a crossing-face object, especially for
animation and raytraced shadows.
View Aligned
Makes the object always face the camera. This is
generally a good choice for trees and other nonplanar
objects.
When the View Aligned option is cleared, the object
maintains a fixed orientation. This can be effective with
planar objects like road signs that you don’t want to
view straight on.
Name
Shows the current name of the object. To change the name, edit the entry.
Image File
Specifies a file name. You can choose Find File to display a standard file

LTSCALE
LWEIGHT
Sets the current lineweight, lineweight display options, and lineweight units
Use lineweights to add width to your objects. Lineweights are useful for the
graphical representation of different objects and information, but they
should not be used to represent specific object widths.
Lineweight can be applied to all graphical objects except TrueType fonts,
raster images (except the image border), points, and solid fills (2D solids).
These exceptions plot with a default lineweight of 0 (the thinnest possible
line that the printer or plotter can plot). The default lineweight value for
objects is BYLAYER; the default lineweight value for layers is set by the Default
option in the Lineweights Settings dialog box. You can also customize lineweights to plot at whatever width you want by using the Plot Style Table
Editor of the PLOT command. See “Control Plotted Lineweight and Linetype”
in the User’s Guide.
Wide polylines in a plan view are displayed at their width setting rather than
their lineweight setting.
Note Objects with lineweights of more than one pixel may increase regeneration time. To optimize AutoCAD performance when working in the Model tab,
set the lineweight display scale to the minimum value, or turn off Display Lineweight altogether.
Format menu: Lineweight
Shortcut menu: Right-click the Lwt button on the status bar and choose
Settings.
Command line: lweight (or 'lweight for transparent use)
The Lineweight Settings dialog box is displayed.
If you enter -lweight at the Command prompt, LWEIGHT displays prompts on
the command line (see page 525).
Lineweight Settings Dialog Box
Sets the current lineweight, sets the lineweight units, controls the display
and display scale of lineweights in the Model tab, and sets the DEFAULT
lineweight value for layers. For a table of valid lineweights, see “Overview of
Lineweights” in the User’s Guide.
LWEIGHT
|
523
Lineweights
Displays the available lineweight values. Lineweight values consist of standard settings including BYLAYER, BYBLOCK, and DEFAULT. The DEFAULT value
is set by the LWDEFAULT system variable, which has an initial value of 0.01
inches or 0.25 mm. All new layers use the default setting. The lineweight
value of 0 plots at the thinnest lineweight available on the specified plotting
device and is displayed at one pixel wide in model space.
Current Lineweight
Displays the current lineweight. To set the current lineweight, select a
lineweight from the lineweight list and choose OK.
Units for Listing
Specifies whether lineweights are displayed in millimeters or inches. You can
also set Units for Listing by using the LWUNITS system variable.
524
|
Millimeters (mm)
Specifies lineweight values in millimeters.
Inches (in.)
Specifies lineweight values in inches.
LWEIGHT
Display Lineweight
Controls whether lineweights are displayed in the current drawing. If
selected, lineweights are displayed in model space and paper space. You can
also set Display Lineweight by using the LWDISPLAY system variable.
AutoCAD regeneration time increases with lineweights that are represented
by more than one pixel. Clear Display Lineweight if AutoCAD performance
slows down when working with lineweights turned on in a drawing. This
option does not affect how objects are plotted.
Default
Controls the DEFAULT lineweight for layers. The initial DEFAULT lineweight is
0.01 inches or 0.25 mm. You can also set the DEFAULT lineweight by using
the LWDEFAULT system variable.
Adjust Display Scale
Controls the display scale of lineweights on the Model tab. On the Model tab,
lineweights are displayed in pixels. Lineweights are displayed using a pixel
width in proportion to the real-world unit value at which they plot. If you
are using a high-resolution monitor, you can adjust the lineweight display
scale to better display different lineweight widths. The Lineweight list reflects
the current display scale.
Objects with lineweights that are displayed with a width of more than one
pixel may increase AutoCAD regeneration time. If you want to optimize
AutoCAD performance when working in the Model tab, set the lineweight
display scale to the minimum value or turn off lineweight display altogether.
LWEIGHT Command Line
If you enter -lweight at the Command prompt, LWEIGHT displays prompts on
the command line.
Current lineweight: current
Enter default lineweight for new objects or [?]:
Enter a valid lineweight or enter ?
The current lineweight value is displayed; if the value is not BYLAYER,
BYBLOCK or DEFAULT, the value is displayed in millimeters or inches.
LWEIGHT
|
525
Default
Lineweight
Sets the current default lineweight. Lineweight values
consist of fixed settings, including BYLAYER, BYBLOCK,
and DEFAULT. Values are calculated in either inches or
millimeters; millimeters are the default. If you enter a
valid lineweight, AutoCAD sets the current default
lineweight to the new value. With any other value,
AutoCAD adjusts the value entered and sets the current
default lineweight to the nearest valid value.
To plot an object with a lineweight that is not found in
the list of fixed lineweight values, you can use the Plot
Style Table Editor to customize plotted lineweights. See
“Control Plotted Lineweight and Linetype,” in the
User’s Guide. The DEFAULT value is set by the LWDEFAULT
system variable and has an initial value of 0.01 inches
or 0.25 mm. The lineweight value of 0 plots at the
thinnest lineweight available on the specified plotting
device and is displayed at a value of one pixel in model
space.
?—List
Lineweights
Displays a list of valid lineweight values in the current
lineweight units.
Note If you save a drawing using the AutoCAD Release 14, or earlier, format,
the drawing preview displays lineweights even though the drawing saved in the
earlier format does not display lineweights.

MASSPROP
Calculates the mass properties of regions or solids
MASSPROP calculates properties of two-dimensional (2D) and threedimensional (3D) objects that are essential in analyzing the characteristics
of the drawn objects.
Inquiry toolbar:
Tools menu: Inquiry ➤ Region/Mass Properties
Command line: massprop
Select objects:
Use an object selection method
If you select multiple regions, only those that are coplanar with the first
selected region are accepted.
MASSPROP displays the mass properties in the text window, and then asks if
you want to write the mass properties to a text file.
Write analysis to a file? <N>: Enter y or n, or press ENTER
If you enter y, MASSPROP prompts you to enter a file name.
The properties that MASSPROP displays depends on whether the selected
objects are regions (and whether the selected regions are coplanar with the
XY plane of the current UCS) or solids. For a list of the parameters that control the MASSPROP units, see Calculations Based on the Current UCS (see page
530).
Regions
The table shows the mass properties AutoCAD displays for all regions.
Mass properties for all regions
Mass property
Description
Area
The surface area of solids or the enclosed area of regions.
Perimeter
The total length of the inside and outside loops of a region. AutoCAD

Mass properties for all regions (continued)
Mass property
Description
Bounding box
The two coordinates that define the bounding box. For regions that are
coplanar with the XY plane of the current user coordinate system
(UCS), the bounding box is defined by the diagonally opposite corners
of a rectangle that encloses the region. For regions that are not
coplanar with the XY plane of the current UCS, the bounding box is
defined by the diagonally opposite corners of a 3D box that encloses
the region.
Centroid
A 2D or 3D coordinate that is the center of area for regions. For regions
that are coplanar with the XY plane of the current UCS, this coordinate
is a 2D point. For regions that are not coplanar with the XY plane of the
current UCS, this coordinate is a 3D point.
If the regions are coplanar with the XY plane of the current UCS, AutoCAD
displays the additional properties shown in the table.
Additional mass properties for coplanar regions
Mass property
Description
Moments of
inertia
A value used when computing the distributed loads, such as fluid
pressure on a plate, or when calculating the forces inside a bending or
twisting beam. The formula for determining area moments of inertia is
area_moments_of_inertia = area_of_interest * radius2
The area moments of inertia has units of distance to the fourth power.
Products of
inertia
Property used to determine the forces causing the motion of an object.
It is always calculated with respect to two orthogonal planes. The
formula for product of inertia for the YZ plane and XZ plane is
product_of_inertiaYZ,XZ = mass * distcentroid_to_YZ * distcentroid_to_XZ
This XY value is expressed in mass units times the length squared.
Radii of
gyration
Another way of indicating the moments of inertia of a solid. The
formula for the radii of gyration is
gyration_radii = (moments_of_ inertia/body_mass)1/2
Radii of gyration are expressed in distance units.

through the centroid. A third value included in the results is somewhere
between the high and low values.
Solids
The table shows the mass properties AutoCAD displays for solids.
Mass properties for solids
Mass property
Description
Mass
The measure of inertia of a body. Because AutoCAD uses a density of
one, mass and volume have the same value.
Volume
The amount of 3D space that a solid encloses.
Bounding box
The diagonally opposite corners of a 3D box that encloses the solid.
Centroid
A 3D point that is the center of mass for solids. AutoCAD assumes a
solid of uniform density.
Moments of
inertia
The mass moments of inertia, which is used when computing the force
required to rotate an object about a given axis, such as a wheel rotating
about an axle. The formula for mass moments of inertia is
mass_moments_of_inertia = object_mass * radiusaxis2
Mass moments of inertia unit is mass (grams or slugs) times the
distance squared.
Products of
inertia
Property used to determine the forces causing the motion of an object.
It is always calculated with respect to two orthogonal planes. The
formula for product of inertia for the YZ plane and XZ plane is
product_of_inertiaYZ,XZ = mass * distcentroid_to_YZ * distcentroid_to_XZ

MEASURE
Places point objects or blocks at measured intervals on an object
Draw menu: Point ➤ Measure
Command line: measure
Select object to measure:
Specify length of segment or [Block]: Specify a distance or enter b
The points or blocks drawn by MEASURE are placed in the Previous selection
set, so you can choose them all by entering p at the next Select Objects
prompt. You can use the Node object snap to draw an object by snapping to
the point objects. You can then remove the points by entering erase
previous.
AutoCAD places the markers in the user coordinate system (UCS) of the
object being measured (except for 3D polylines in the current UCS). Markers
are always placed on the object, regardless of the elevation settings.

If you use point objects for the markers, you can make the points easier to see
by changing their appearance with the PDMODE system variable.
Length of
Segment
Places point objects at the specified interval along the
selected object, starting at the endpoint closest to the
point you used to select the object.
Measurement of closed polylines starts at their initial
vertex (the first one drawn).
Measurement of circles starts at the angle from the
center set as the current snap rotation angle. If the snap
rotation angle is 0, then the measurement of the circle
starts to the right of center, on its circumference.

top
Top
Draws the multiline below the cursor, so that the line
with the most positive offset is at the specified points.
Zero
Draws the multiline with its origin centered at the
cursor, so that the MLSTYLE Element Properties offset of
0.0 is at the specified points.
Bottom
Draws the multiline above the cursor, so that the line

Enter mline scale <current>: Enter a scale or press ENTER
MLINE
|
565
The scale factor is based on the width established in the multiline style
definition. A scale factor of 2 produces a multiline twice as wide as the style
definition. A negative scale factor flips the order of the offset line—the
smallest on top when the multiline is drawn from left to right. A negative
scale value also alters the scale by the absolute value. A scale factor of 0
collapses the multiline into a single line. For information about the multiline
style definition, see MLSTYLE.

and saves, adds, and renames them. You can also create or edit a description
of a style.
Current
Displays and sets the current multiline style. Select a
name from the list to make it current. If there are
multiple styles, the name of the current style is selected.
The list of multiline styles can include externally
referenced multiline styles—that is, multiline styles
that exist in an externally referenced drawing (xref).
AutoCAD displays externally referenced multiline style
names using the same syntax it uses for other externally
dependent nongraphical objects. See “Overview of
External References” in the User’s Guide.
Note You cannot edit the element and multiline
properties of the STANDARD multiline style or any
multiline style that is being used in the drawing. If you try
to edit the options in either the Element Properties dialog
box (see page 569) or the Multiline Properties dialog box

MODEL
Switches from a layout tab to the Model tab
Command line: model
On the Model tab, you can create drawings in model space. The Model tab
automatically sets the TILEMODE system variable to 1, and you can create
model viewports to display various views of your drawing. Once you’ve completed your drawing, you can choose a layout tab to begin designing a layout
environment from which to plot.
For possible performance gains when you switch between layout tabs or
between the Model tab and a layout tab, use the LAYOUTREGENCTL system
variable to control how the display list is updated.
Note The Model tab replaces the TILE button that appeared on the status bar
in earlier releases of AutoCAD.
See Also
See “Work in Paper Space and Model Space” in the User’s Guide.
System Variables
LAYOUTREGENCTL specifies how the display list is
updated in the Model and layout tabs.

The two points you specify define a displacement vector that indicates how
far the selected objects are to be moved and in what direction. If you press
ENTER at the Specify Second Point of Displacement prompt, the first point is
interpreted as relative X,Y,Z displacement. For example, if you specify 2,3 for
the base point and press ENTER at the next prompt, the object moves 2 units
in the X direction and 3 units in the Y direction from its current position.

MSLIDE
Creates a slide file of the current model viewport or the current layout
Command line: mslide
The Create Slide File dialog box (a standard file selection dialog box) is
displayed. Enter a file name or select a slide (SLD) file from the list. A slide
file is a raster image of a viewport.
In model space, MSLIDE makes a slide file of the current viewport only. In
paper space, MSLIDE makes a slide file of the paper space display, including
all viewports and their contents.
Off-screen portions of the drawing, or layers that are off or frozen, are not
included in the slide.
Use the VSLIDE command to view slides, or the SLIDELIB utility to create a
slide library.
When you view slides of images shaded with the -SHADE command in a larger
window or at a higher resolution than was used for creating the slide, black
lines may appear interspersed among the lines of the shaded image. To avoid
this situation, use a full screen that is set at the highest resolution when
creating slides.
See Also
See “Prepare Slides for Image Tile Menus” in the Customization Guide.
Commands
VSLIDE displays slide files in the current viewport.
Utilities
SLIDELIB creates slide library (SLB) files. This utility is
found in the AutoCAD Support directory.
MSPACE
Switches from paper space to a model space viewport
AutoCAD operates in either model space or paper space. You use model space
(the Model tab) to do drafting and design work and to create two-dimensional drawings or three-dimensional models. You use paper space (a layout
tab) to create a finished layout of a drawing for plotting.
MSLIDE
|
575
When you are in a layout, you can enter mspace on the command line to
make the last viewport in the layout current, and then work in model space
in that viewport within the layout. You can switch to model space by doubleclicking a viewport, and you can switch to paper space by double-clicking an
area of paper space.
Command line: mspace
See Also
See “Work in Paper Space and Model Space” in the User’s Guide.
Commands
PSPACE switches from model space to paper space.
VPORTS creates a new viewport object and turns on
existing viewport objects. VPLAYER sets the visibility for
layers in specific viewports.
System Variables
PSVPSCALE sets the default viewport scale factor applied
to newly created viewports. PSLTSCALE controls paper
space linetype scaling. VISRETAIN specifies precedence
of settings for external reference layers. MAXACTVP
specifies the maximum number of viewports to regenerate. DIMLFAC controls scaling for linear dimensioning
measurements.
MTEXT
Creates multiline text
MTEXT creates paragraphs that fit within a boundary that defines the width
of the paragraph and its location in the drawing. Each multiline text (mtext)
object is a single object, regardless of the number of lines it contains. The text
boundary, although not plotted, printed, or displayed, remains part of the
object’s framework.
Draw toolbar:

Font
Specifies a font for new text or changes the font of
selected text. TrueType® fonts are listed by font family
name. AutoCAD compiled shape (SHX) fonts are listed
by the name of the file in which the fonts are stored.
Custom fonts or third-party fonts are displayed in the
editor with Autodesk-supplied proxy fonts. A sample
drawing (truetype.dwg) showing each font is provided in
the sample directory.
Text Height
Sets the character height in drawing units for new text
or changes the height of selected text. If the current text
style has no fixed height, the text height is the value
stored in the TEXTSIZE system variable. A multiline text
object can contain characters of various heights.
Bold
Turns on and off bold formatting for new or selected
text. This option is available only for characters using
TrueType fonts.
Italic
Turns on and off italic formatting for new or selected
text. This option is available only for characters using
TrueType fonts.

changes to either text content or text formatting. You
can also use CTRL + Z .
Redo
Redoes actions in the Multiline Text Editor, including
changes to either text content or text formatting. You
can also use CTRL + Y .
Stack
Creates stacked text, for example, fractions, if the
selected text contains stack characters. Also, unstacks
text if stacked text is selected. When the stack
characters, carat (^), forward slash (/), and pound sign
(#), are used, the text to the left of the stack character is
stacked on top of the text to the right.
By default, text that contains a carat converts to leftjustified tolerance values. Text that contains the
forward slash converts to center-justified fractional
numbers; the slash is converted to a horizontal bar the
length of the longer text string. Text that contains the
pound sign converts to a fraction separated by a
diagonal bar the height of the two text strings. The
578
|
MTEXT
characters above the diagonal fraction bar are bottomright aligned; the characters beneath the diagonal bar
are top-left aligned.
Text Color
Specifies a color for new text or changes the color of
selected text.

Justify
Determines both text justification and text flow, for new or selected text, in
relation to the text boundary. The current justification (Top Left, by default)
is applied to new text. The text is justified within the specified rectangle
based on the justification setting and one of nine justification points on the
rectangle. The justification point is based on the first point used to specify
the rectangle. Text is center-, left-, or right-justified with respect to the left
and right text boundaries. Spaces entered at the end of a line are included as
part of the text and affect the justification of the line. Text flow controls
whether text is aligned from the middle, the top, or the bottom of the paragraph with respect to the top and bottom text boundaries.

MVSETUP
Sets up the specifications of a drawing
Command line: mvsetup
When you enter mvsetup at the command line, the prompts displayed
depend on whether you are on the Model tab (model space) or on a layout
tab (paper space).
MVSETUP
|
595
On the Model tab, you set the units type, drawing scale factor, and paper size
from the command line using MVSETUP. Using the settings you provide,
AutoCAD draws a rectangular border at the drawing limits.
On a layout tab, you can insert one of several predefined title blocks into the
drawing and create a set of layout viewports within the title block. You can
specify a global scale as the ratio between the scale of the title block in the
layout and the drawing on the Model tab. The Model tab is most useful for
plotting multiple views of a drawing within a single border.
To easily specify all layout page settings and prepare your drawing for plotting, you can also use the Page Setup dialog box, which is automatically
displayed when you select a layout in a new drawing session.
Using MVSETUP on the Model Tab
When the TILEMODE system variable is on (the default), AutoCAD displays
the following prompt:
Enable paper space? [No/Yes] <Y>: Enter n or press ENTER
Pressing ENTER turns off TILEMODE and proceeds as described in the following section, “Using MVSETUP on a Layout Tab.”

Units
Indicates the format in which you enter and in which AutoCAD displays
coordinates and measurements. Several formats are available in AutoCAD.
Two of them, Engineering and Architectural, have a specific base unit
(inches) assigned to them. You can select from other measurement styles that
can represent any convenient unit of measurement.
Note You control the precision (the number of decimal places displayed in all
measurements) by using the Advanced Setup wizard or the UNITS command.
The default precision used by Quick Setup is four (0.0000).
Decimal
Displays measurements in decimal notation.
Engineering
Displays measurements in feet and decimal inches.
Architectural
Displays measurements in feet, inches, and fractional
inches.
Fractional
Displays measurements in mixed-number (integer and
fractional) notation.
Scientific
Displays measurements in scientific notation (numbers
expressed in the form of the product of a decimal
number between 0 and 10 and a power of 10).
Area
Indicates the width and length in full-scale units of what you plan to draw.
This setting limits the area of the drawing covered by grid dots when the grid
is turned on. When limits checking is turned on with the LIMITS command,
this setting also restricts the coordinates you can enter to within the rectangular area. You can change the drawing area and turn limits checking on and
off with the LIMITS command.

Angle Direction, and Area. As you work in this wizard, choose Back and Next
to navigate between pages; choose Finish on the last page to close the wizard
and create the new drawing with the settings you specified.
You can later change units, angle, angle measure, and angle direction using
the UNITS command, and you can change area using the LIMITS command.
Units
Indicates the unit format and precision. The unit format is the format in
which you enter and in which AutoCAD displays coordinates and measurements. The Units page of the Quick Setup wizard includes the same formats.
See “Units” on page 609 for more information.
The unit precision specifies the number of decimal places or the fractional
size for displaying linear measurements.

Surveyor
Displays angles in surveyor’s units.
Angle Measure
Indicates the direction of the 0 angle for the entry of angles. When you enter
an angle value in AutoCAD, AutoCAD measures the angle either counterclockwise or clockwise from the compass direction that you select on this
page. You control the counterclockwise/clockwise direction on the Angle
Direction page.
East
Specifies the compass direction east as the 0 angle.
North
Specifies the compass direction north as the 0 angle.
West
Specifies the compass direction west as the 0 angle.
South
Specifies the compass direction south as the 0 angle.
Other
Specifies a direction other than east, north, west, or
south. Enter a specific compass angle to treat as the 0
angle.
Angle Direction
Indicates the direction from the 0 angle in which you enter and in which
AutoCAD displays positive angle values: counterclockwise or clockwise.
Area
Indicates the width and length in full-scale units of what you plan to draw.
This setting limits the area of the drawing covered by grid dots when the grid
is turned on. When limits checking is turned on with the LIMITS command,
this setting also restricts the coordinates you can enter to within the rectangular area. You can change the drawing area and turn limits checking on and
off with the LIMITS command.

629
View Geometry to Load
Displays the selected view and available views in the drawing. Only model
space views are available for loading. You can load paper space geometry by
loading the layer that the paper space geometry is drawn on.
View Name
Displays the currently selected view. Geometry that is
common to both the selected view and the layers is
loaded into the drawing.
View List
Displays all the model space views available in the
selected drawing file. When a view is selected,
AutoCAD loads only the geometry in the selected view.
The default view is Extents. Geometry that is common
to both the selected view and the layers is loaded into
the drawing. You can load geometry from only one
view.
You can use the PARTIALOAD command to load
additional geometry into a partially open drawing.
Note When a drawing is partially open, named objects are still loaded into the
file along with the specified geometry from the selected view. All views are still
available in the partially open drawing, but only geometry from the view
specified to load is displayed in the drawing.
630
|
OPEN
Layer Geometry to Load
Displays all the layers available in the selected drawing file. The geometry on
selected layers is loaded into the drawing, including both model space and
paper space geometry. The default loads no layer geometry into the drawing,
but you can load geometry from one or more layers. If you specify to load no
layer geometry into the drawing, no geometry from the selected view is
loaded either because no layer geometry in that view or in the entire drawing
is loaded. Xref-dependent layers are displayed in the Layer Geometry to Load
list only if the selected drawing was last saved with the VISRETAIN system variable set to 1. Any layers created in the xref since the xref was loaded into the
selected drawing are not displayed in the Layer Geometry to Load list.
You can use the PARTIALOAD command to load additional geometry into a
partially open drawing.
Note When a drawing is partially open, named objects are still loaded into the
file along with the specified geometry from the selected layers. All layers are still
available in the partially open drawing, but only geometry from the layers
specified to load appears in the drawing.
Layer Name
Displays the layer names in the selected drawing.
Load Geometry
Loads geometry from the layer when the drawing is
opened.
Load All
Loads geometry from all layers when the drawing is
opened. You can right-click and use the shortcut menu
to load geometry from all layers into the drawing.
Clear All
Loads no geometry from any layer when the drawing is
opened. No geometry at all is loaded, including
geometry specified to load from a view. You can rightclick and use the shortcut menu to load no geometry
into the drawing.
Index Status
Displays whether the selected drawing file contains a spatial or layer index.
INDEXCTL controls whether layer and spatial indexes are saved with the
drawing file.
OPEN
|
631
Use Spatial Index
Controls whether a spatial index is used when partially
opening a drawing. AutoCAD uses a spatial index to
locate what portion of the drawing is read; this
minimizes the time required to open the drawing. If a
drawing does not contain a spatial index, this option is
unavailable.
Spatial Index
Displays whether the selected drawing file contains a
spatial index. A spatial index organizes objects based on
their location in space. When partially opening a
drawing, AutoCAD uses a spatial index to locate what
portion of the drawing is read; this minimizes the time
required to open the drawing.
Layer Index
Displays whether the selected drawing file contains a
layer index. A layer index is a list showing the objects
that are on each layer. When partially opening a
drawing, AutoCAD uses a layer index to locate what
portion of the drawing is read; this minimizes the time
required to open the drawing.
Unload All Xrefs on Open
Loads all external references when opening the drawing. Selecting this
option enhances the opening process. If you partially open a drawing that
contains a bound xref, only the portion of the xref that is loaded (defined by
the selected view) is bound to the partially open drawing.
Open
Opens the drawing file, loading only combined geometry from the selected
view and layers.
OPEN Command Line

Crosshair Size
Controls the size of the crosshairs. The valid range is from 1 to 100 percent
of the total screen. At 100 percent, the ends of the crosshairs are never visible.
When the size is decreased to 99 percent or below, the crosshairs have a finite
size, and the ends of the crosshairs are visible when situated at the edge of
the drawing area. The default size is 5 percent. (CURSORSIZE system variable)
Display Resolution
Controls the quality of the display of objects. If you set high values to
improve display quality, the impact on performance is significant.
Arc and Circle
Smoothness
640
|
OPTIONS
Controls the smoothness of circles, arcs, and ellipses. A
higher number produces smoother objects, but
AutoCAD requires more time to regenerate, pan, and
zoom the objects. You can improve performance by
setting this option to a low value such as 100 for
drawing, and increasing the value for rendering. The
valid range is 1 to 20,000. The default setting is 1000.
This setting is saved in the drawing. To change the
default for new drawings, consider specifying this
setting in the template files on which you base your
new drawings.
This value is also controlled by the VIEWRES command.
Segments in a
Polyline Curve
Sets the number of line segments to be generated for
each polyline curve. The higher the number, the greater
the performance impact. Set this option to a low value
such as 4 to optimize performance for drawing. Values
range from –32767 to 32767. The default setting is 8.
This setting is saved in the drawing. (SPLINESEGS system
variable)
Rendered Object
Smoothness
Controls the smoothness of shaded and rendered
curved solids. AutoCAD multiplies the value you enter
for Rendered Object Smoothness by the value you enter
for Arc and Circle Smoothness to determine how to
display solid objects. To improve performance, set
Rendered Object Smoothness to 1 or less when
drawing. A higher number decreases display
performance and increases rendering time. The valid
range is 0.01 to 10. The default setting is 0.5. This
setting is saved in the drawing. (FACETRES system
variable)
Contour Lines per
Surface
Sets the number of contour lines per surface on objects.
A higher number decreases display performance and
increases rendering time. The valid range is 0 to 2047.
The default setting is 4. This setting is saved in the
drawing. (ISOLINES system variable)
Display Performance
Controls display settings that affect AutoCAD performance.
Pan and Zoom
with Raster Image
Controls the display of raster images when you use
Realtime PAN and ZOOM. Clear this option to optimize
performance. If dragging display is turned on and you
select Pan and Zoom with Raster Image, a copy of the
image moves with the cursor as you reposition the
original image. Dragging display controls whether an
outline of the object is displayed while you drag it. The
DRAGMODE system variable controls dragging display.
(RTDISPLAY system variable)
OPTIONS
|
641
Highlight Raster
Image Frame
Only
Controls the display of raster images during selection. If
this option is selected, only the frame of the raster
image is highlighted when selected. Select this option
to optimize performance. (IMAGEHLT system variable)
True Color Raster
Images and
Rendering
Controls whether raster images or renderings are
displayed at optimum quality. Selecting True Color
Raster Images and Rendering enables AutoCAD to
display images in True Color or at the highest display
quality available for the system. Increasing the amount
of colors in the system display setting significantly
decreases display performance. Clearing this option or
reducing the color palette in the system display settings
optimizes performance.
Apply Solid Fill
Displays solid fills in objects. Objects affected by FILL
include hatches (including solid-fill), two-dimensional
solids, wide polylines, multilines and traces. You must
regenerate the drawing by using REGEN or REGENALL for
this setting to take effect. This setting is saved in the
drawing. Clear this option to optimize performance.
(FILLMODE system variable)
Show Text
Boundary Frame
Only
Displays the frames for text objects instead of
displaying the text objects. After you select or clear this
option, you must use REGEN to update the display. This
setting is saved in the drawing. Select this option to
optimize performance. (QTEXTMODE system variable)
Show Silhouettes
in Wireframe
Controls whether silhouette curves of 3D solid objects
are displayed as wireframes. This option also controls
whether mesh is drawn or suppressed when a 3D solid
object is hidden. This setting is saved in the drawing.
Clear this option to optimize performance. (DISPSILH
system variable)
Reference Fading Intensity
Specifies the fading intensity value for objects during in-place reference
editing. With in-place reference editing, you can edit a block reference or
external reference from within the current drawing. While references are
being edited in-place, objects that are not being edited are displayed at a
lesser intensity than objects that can be edited. The valid range is 0 through
90 percent. The default setting is 50 percent. (XFADECTL system variable)
642
|
OPTIONS
Open and Save Tab (Options Dialog Box)
Controls options that relate to opening and saving files in AutoCAD.
File Save
Controls settings related to saving a file in AutoCAD.
Save As
Displays the valid file formats used when saving a file
with SAVE, SAVEAS, and QSAVE. The file format selected
for this option is the default format that all drawings
are saved as when you use SAVE, SAVEAS, and QSAVE.
Saving an AutoCAD 2004 file to any DXF format affects
performance. Set the Save As option to AutoCAD 2004
Drawing to optimize performance while saving.
Note AutoCAD 2000 is the drawing file format used by
the AutoCAD 2000, AutoCAD 2000i, and AutoCAD 2002
releases.
Save a Thumbnail
Preview Image
Displays an image of the drawing in the Preview area of
the Select File dialog box. (RASTERPREVIEW system
variable)
OPTIONS
|
643
Incremental Save
Percentage
Sets the percentage of potentially wasted space in a
drawing file. When the specified percentage is reached,
AutoCAD performs a full save instead of an incremental
save. Full saves eliminate wasted space. If you set
Incremental Save Percentage to 0, every save is a full
save.
Although incremental saves increase the size of your
drawing, do not set a very low value. Low values
degrade performance because AutoCAD performs timeconsuming full saves more often. For optimum
performance, set the value to 50. If hard disk space
becomes an issue, set the value to 25. If you set the
value to 20 or less, performance of the SAVE and SAVEAS
commands slows significantly. (ISAVEPERCENT system
variable)
File Safety Precautions
Assists in avoiding data loss and in detecting errors.
Automatic Save
Saves your drawing automatically at the intervals you
specify. You can specify the location of all Autosave files

PAN Command Line
If you enter -pan at the Command prompt, PAN presents alternative prompts
on the command line.
This version of PAN works in two ways. You can specify a single point, indicating the relative displacement of the drawing with respect to the current
location, or (more commonly) you can specify two points, in which case
AutoCAD computes the displacement from the first point to the second
point.
2
You cannot use PAN transparently during VPOINT or DVIEW, or while another
ZOOM, PAN, or VIEW command is in progress.

Uses the vertices of the selected polyline as the control points, or frame, of a
curve approximating a B-spline. This curve, called a spline-fit polyline, passes
through the first and last control points unless the original polyline was
closed. The curve is pulled toward the other points but does not necessarily
pass through them. The more control points you specify in a particular part
of the frame, the more pull they exert on the curve. AutoCAD can generate
quadratic and cubic spline-fit polylines.
Spline-fit polylines are very different from the curves produced by the Fit
option. Fit constructs pairs of arcs that pass through every control point.
Both of these curves are different from true B-splines produced with the
SPLINE command.

If the original polyline included arc segments, they are straightened when
the spline's frame is formed. If the frame has width, the resulting spline
tapers smoothly from the width of the first vertex to the width of the last
vertex. All intermediate width information is ignored. Once spline-fit, the
frame, if displayed, is shown with zero width and CONTINUOUS linetype.
Tangent specifications on control point vertices have no effect on splinefitting.
When a spline-fit curve is fit to a polyline, the spline-fit curve's frame is
stored so that it can be recalled by a subsequent decurving. You can turn a
spline-fit curve back into its frame polyline by using the PEDIT Decurve
option. This option works on fit curves in the same manner as it does on
splines.
Spline frames are not usually displayed on the screen. If you want to see
them, set the SPLFRAME system variable to 1. Next time the drawing is regenerated, AutoCAD draws both the frame and the spline curve.
SPLFRAME set to 0
SPLFRAME set to 1

and SCALE operate on both the
spline curve and its frame, whether the frame is visible or not.
EXTEND changes the frame by adding a new vertex where the initial or
final line of the frame intersects the boundary geometry.
BREAK, TRIM, and EXPLODE delete the frame and generate a polyline with
only the fit spline, which is consistent with fit curves, where the curve fitting is permanent.
OFFSET generates a polyline with only the fit spline, which is consistent
with its behavior with fit curves.
DIVIDE, MEASURE, the Object option of AREA, HATCH, FILLET, and
CHAMFER see only the fit spline, not the frame.
STRETCH refits the spline to the stretched frame after a spline is stretched.
The Join option of PEDIT decurves the spline and discards the spline information of the original and any added polylines. Once the Join operation is
complete, you can fit a new spline to the resulting polyline.

The Next and Previous options move the X marker only to points on the
frame of the spline, whether visible or not.
The Break option discards the spline.
The Insert, Move, Straighten, and Width options automatically refit the
spline.
The Tangent option has no effect on splines.
Object snap uses only the spline-fit curve itself, not the frame. If you want to
snap to the frame control points, use PEDIT to recall the polyline frame first.
The SPLINETYPE system variable controls the type of spline curve approximated. Setting SPLINETYPE to 5 approximates a quadratic B-spline. Setting
SPLINETYPE to 6 approximates a cubic B-spline.
quadratic B-Spline
cubic B-Spline
You can examine or change the fineness or coarseness of the spline approximation with the SPLINESEGS system variable, or you can use AutoLISP. The
default value is 8. If you set the value higher, a greater number of line
segments are drawn and the approximation to the ideal spline becomes more
precise. The generated spline occupies more space in the drawing file and
takes longer to generate.
If you set SPLINESEGS to a negative value, AutoCAD generates segments using
the absolute value of the setting and then applies a fit-type curve to those
segments. Fit-type curves use arcs as the approximating segments. Using arcs
yields a smoother generated curve when few segments are specified, but the
curve can take longer to generate.
SPLINESEGS set to 1
SPLINESEGS set to 10
To change the number of segments used to fit an existing spline, change
SPLINESEGS and respline the curve. You do not have to decurve it first.

Decurve
Removes extra vertices inserted by a fit or spline curve and straightens all
segments of the polyline. Retains tangent information assigned to the polyline vertices for use in subsequent fit curve requests. If you edit a spline-fit
polyline with commands such as BREAK or TRIM, you cannot use the Decurve
option.
Ltype Gen
Generates the linetype in a continuous pattern through the vertices of the
polyline. When turned off, this option generates the linetype starting and
ending with a dash at each vertex. Ltype Gen does not apply to polylines
with tapered segments.
Enter polyline linetype generation option [ON/OFF] <current>: Enter on or off,
or press ENTER

3D Polyline Selection
If you select a 3D polyline, AutoCAD prompts:
Enter an option [Close/Edit vertex/Spline curve/Decurve/Undo]: Enter an option
or press ENTER
If the polyline you select is closed, Open replaces the Close option in the
prompt.
Close
Creates the closing segment of the polyline, connecting the last segment
with the first. AutoCAD considers the polyline open unless you close it with
Close.
Open
Removes the closing segment of the polyline. AutoCAD considers the polyline closed unless you open it with Open.

Edit Vertex
Performs various editing tasks on one vertex of the polyline and segments
that follow it.
Enter a vertex editing option
[Next/Previous/Break/Insert/Move/Regen/Straighten/eXit <current>: Enter an
option or press ENTER
Pressing ENTER accepts the current default, which is either Next or Previous.
Next
Moves the X marker to the next vertex. The marker does not wrap around
from the end to the start of the polyline, even if the polyline is closed.
Previous
Moves the X marker to the previous vertex. The marker does not wrap
around from the start to the end of the polyline, even if the polyline is closed.
Break
Saves the location of the marked vertex while you move the X marker to any
other vertex.
Enter an option [Next/Previous/Go/eXit] <current>: Enter an option or press
ENTER
Next
Moves the X marker to the next vertex. The marker
does not wrap around from the end to the start of the
polyline, even if the polyline is closed.
Previous
Moves the X marker to the previous vertex. The marker
does not wrap around from the end to the start of the
polyline, even if the polyline is closed.
Go
Deletes any segments and vertices between the two
vertices you specify and returns to Edit Vertex mode.
Exit
Exits Break and returns to Edit Vertex mode.
If one of the specified vertices is at an end of the polyline, the polyline is
truncated. If both specified vertices are at endpoints of the polyline, or if just
one vertex is specified and it is at an endpoint, you cannot use Break mode.
Insert
Adds a new vertex to the polyline after the marked vertex.

Moves the X marker to the previous vertex.
Go
Deletes any segments and vertices between the two
vertices you select, replaces them with single straight
line segments, and returns to Edit Vertex mode. If you
specify only one vertex by entering go without moving
the X marker, the segment following that vertex is
made straight if it is an arc.
Exit
Exits Straighten and returns to Edit Vertex mode.
To remove an arc segment that connects two straight segments of a polyline
and then to extend the straight segments until they intersect, use the FILLET
command with a fillet radius of 0.
Exit
Exits Edit Vertex mode.
Spline Curve
Fits a 3D B-spline curve to its control points. The SPLFRAME system variable
controls the accuracy and display of the control points for the 3D B-spline,
whose curves can be approximated only by line segments. AutoCAD ignores
negative values for spline segments.

System Variables
PLINETYPE specifies whether AutoCAD uses optimized
2D polylines. SPLFRAME, if set to 1, displays the control
polygon for spline-fit polylines, the fit surface of a polygon mesh, and the invisible edges of a 3D face or
polyface mesh. SPLINESEGS stores the number of line
segments to be generated for each spline patch.
SPLINETYPE controls the type of spline curve that
AutoCAD generates. SURFTYPE controls the type of surface that the Edit Vertex option fits to a 3D polygon
mesh. SURFU controls the surface density in the M
direction. SURFV controls the surface density in the N
direction.
PFACE
Creates a three-dimensional polyface mesh vertex by vertex
A polyface mesh is similar to a 3D mesh. Each mesh is constructed vertex by
vertex, so you can create irregular surface shapes. You define a polyface mesh
by specifying each vertex and then associating those vertices with faces in
the mes
