Chapter
Advanced Text Objects
When annotating a drawing there are a number of different tools that can be used
to accurately and efficiently communicate the information in a drawing. These
include the annotation scale features to efficiently reuse and annotate objects and
views. In addition, you learn how to use fields, and control the drawing order of
text and other objects.
Learning Objectives in this Chapter
• Create annotative styles for dimensions, multileaders, text, etc.
• Add annotative objects at different scales.
• Add fields to automate textual information in blocks and attributes.
Sa
• Control the display of objects and annotation in relation to items around them.

The Annotation Scale features enable you to avoid creating
multiple copies of the same annotation objects at different
scales. This makes it easier to quickly dimension drawings that
contain views at different scales. Using Annotation Scale, you
can control which dimensions, text, etc., display in each scaled
detail viewport, as shown in Figure 2–1.
Figure 2–1
•
Annotation objects include Single Line Text, Multiline Text,
Text Styles, Dimensions, Dimension Styles, Multileaders,
Multileader Styles, Geometric Tolerances, Blocks, Attributes,
and Hatches.
Hint: Linetypes and Annotation Scale
Linetype spacing is controlled by the Annotation Scale through
the msltscale system variable. This variable is set per drawing
using templates.
When set to 1 (the default in the template files supplied with
the AutoCAD® software), linetypes are automatically scaled
to the annotation scale.
•
When set to 0, they are not scaled to the annotation scale.

1. In a layout, switch to Paper Space and set up the viewports
as required.
2. Select a viewport by selecting its border.
3. In the Status Bar, click
(Viewport Scale) and select
a scale in the list, as shown in Figure 2–5. The Annotation
Scale automatically updates to match. Changing the
Annotation Scale also changes the Viewport Scale.
Figure 2–5
4. (Optional) Click
(Lock/Unlock Viewport) to lock the
viewport so that the scale and location cannot change.

Hint: Changing Scale of Annotative Objects
In a viewport, when Zoom commands are used or the scale
changes in the Viewports toolbar, the scale of the annotative
objects is not modified. You must modify the Viewport Scale in
the Status Bar for the annotative objects to change scale.
Annotation Scale is linked to the Viewport Scale, therefore,
annotative objects (such as dimensions and text) display in
layout viewports that have the same scale. If the Viewport Scale
is changed, the annotative objects are not displayed. To ensure
they remain displayed, add annotation scales to objects enabling
them to be displayed in viewports of different scales. For
example, you might want the room names to display in each
view while the dimensions display in specific viewports, as
shown in Figure 2–8.

When a viewport’s Viewport Scale is changed, the annotation
objects displayed within it change as well. How the objects
behave depends on how you set the annotation visibility and
whether or not the scale is automatically added to the object.
Annotation Visibility: When toggled Off, only annotative objects
with the current scale display. It is recommended that you use this
option by default. It displays objects that are to be plotted.
Annotation Visibility: When toggled On, annotative objects for all
of the scales display. Use when you need to add or remove an
annotative object to the current scale.
Automatically add scales to annotative objects when the
annotation scale changes: When toggled Off, annotation scales
are not automatically added to objects in the viewport.
Automatically add scales to annotative objects when the
annotation scale changes: When toggled On, any annotation
objects in the drawing are updated to match the new annotation
scale.
•
When you add a scale to an object, a scale representation of
that object is created.
•
When you select an annotative object that has more than one
scale, all of its scale representations display, as shown on the
right in Figure 2–9. There is no limit to the number of scales
that can be added to an object. However, too many scales
can be confusing when you use grips to edit the object.
Sa
Figure 2–9

•
If you modify the information contained in the annotation, all
of the scale representations are updated.
•
You can use grips to edit each scale representation
separately in its associated viewport to suit the location.

Fields in Blocks
2–16
Most fields can be included in a block definition and update
within the block. For instance, the Filename field in a block
updates with the name of the drawing file in which the block is
inserted.
•
Fields that do not update in blocks include those in the Plot
category (PaperSize, PlotScale, etc.) and in the Sheet Set
category. The value of these fields depends on the layout in
which they have been placed or their location in Model/Paper
Space.
•
Similar to block insertions, fields in Xrefs use values from the
host file (such as the filename).
© 2017, ASCENT - Center for Technical Knowledge®
Advanced Text Objects
Fields can also be added to blocks by using a field to define the
value of an attribute. For example, data in a title block, such as
Filename or Title, would typically be created as attributes. If you
use fields, these attributes automatically obtain their values from
the drawing’s properties. Having the field as an attribute value
makes it easier to edit the value in the block as required.

As you are annotating a drawing, you might need to adjust the
order of the overlapping objects. For example, you might have
hatching on top of text but actually need to have the text on top
of the hatching, as shown in Figure 2–30. You might also need to
have a boundary around the text so that it stands out more
prominently.
Figure 2–30
You can use several tools to make these adjustments, three of
which include the following:
Draw Order
•
You can select a
(Draw order) in the Home tab>
expanded Modify panel.
•
The various Draw Order options are listed as shown in
Figure 2–31. You can change the objects to a different draw
order by selecting the required option in the drop-down list.
Sa
You can also select a
draw order by
right-clicking on an
object and selecting
Draw Order.
When you create new objects, they are created on top of existing
objects in the drawing by default. Some objects, such as a wide
polyline or hatch, can cover objects that were drawn earlier.

A few of the most commonly used options include:
Puts the object at the top of the drawing order (in
front of all of the other objects).

(behind all of the other objects).
•
When you assign a Draw Order to an object it maintains its
position even after editing.
•
A copied object inherits the Draw Order status of the original
object.
You can set the draw order of hatches while creating them by
selecting an option in the Hatch Creation contextual tab>
expanded Options panel. The default option, Send Behind
Boundary, makes it easier to select the hatch boundary after the
hatching has been applied. The other options are shown in
Figure 2–32.

Adding a
Wipeout
Another useful tool for overlapping objects, hatches, or other
images is Wipeout. A wipeout puts a blank image on top of
objects in an area that you want to mask or hide. For example,
you could use a wipeout to mask objects behind text (as shown
in Figure 2–38) or to break a dimension line where another one
passes over it.
