Chapter 1. Overview
The basis of JetStream Roamer is its ability to walk through any size model in real time. JetStream
guarantees a user-defined frame rate using a unique algorithm which automatically calculates which
items to render first during navigation, based on the size of items and distance from the viewpoint. Items
which JetStream does not have time to render are therefore sacrificed or "dropped out" in the name of
interactivity. These items are, of course, rendered when navigation ceases. The amount of drop-out
depends on several factors including: hardware (in particular graphics card and driver performance - for a
list of recommended graphics cards, visit www.navisworks.com [http://www.navisworks.com]), as well as
the size of the JetStream navigation window and the size of the model. If you wish to reduce drop-out
during navigation, you have the option to reduce frame rate and therefore trade it off against drop-out.
When working with truely large "supermodels" in JetStream, you will require a sufficient amount of RAM
to load and review the data. JetStream employs JetStream technology which optimizes the usage of the
available RAM. Before running out of memory, JetStream will page unnecesary data to the hard disk,
freeing up space for loading to continue. JetStream technology also enables the user to commence
navigating the supermodel, before it has completely loaded into memory.
JetStream is large address aware, utilizing any additional memory assignment following the 3GB switch
available on Windows XP systems.
JetStream is sold as a base product, Roamer, and a set of plugins that "plug-in" to it for additional
functionality such as for file publishing, photo-realistic rendering, clash detection and construction
sequencing. This set of user guides is organized by product, so there is a book for base Roamer, and one
for each plugin.
To start Roamer, double click on the Roamer icon on the desktop, or go to Start, Programs, JetStream,
Roamer. The following chapters will describe the interface in more detail.
JetStream contains full context sensitive Help. Click
and click over the toolbar button or menu
command to display the appropriate Help topic. Or alternatively go to the Help menu.
For more hints, tips and answers to frequently asked questions, see Chapter 18, Getting Help or
alternatively, go to the JetStream website at www.navisworks.com [http://www.navisworks.com].

Chapter 2. File Management
With JetStream Roamer you can open a wide variety of native 3D CAD file types without having to have
the CAD application on your machine. See Chapter 3, Converting Files for more detailed information on
these file formats and their options. File management all happens with the File menu and the Standard
toolbar.

File Management
To create a new file
•
Go to File, New
or
•
Click New
on the Standard toolbar.
2.3. Refreshing Files
When working in JetStream, it is possible that others may be working on the CAD files you are currently
reviewing. For example, if you are coordinating various disciplines on a project, then you may have an
overall .nwf file referencing numerous design files. During the iterative stages of the project, any member
of the design team could potentially be modifying their CAD files. To ensure the data you are reviewing is
current, JetStream provides a refresh function to reload any files that have been modified since
commencing the review session. This feature does not reload all of the files you have loaded, merely
those modified since last opening them.
To refresh your scene with the latest versions of the currently loaded model files
•
Go to File, Refresh...
or
•
Click Refresh
on the Standard toolbar.
2.4. Opening Files
With JetStream Roamer you can open a wide variety of native CAD file types without having to have the
CAD application on your machine. See Chapter 3, Converting Files for more detailed information on these
file formats and their options. To open a model file
•
Go to File, Open...
or
•
Click Open
on the Standard toolbar.
Note
The standard Open dialog use of Shift and Control keys allows multiple files to be selected and

appended to the current set of models.
2.5. Opening Files via URL
With JetStream Roamer you can open JetStream published .nwd files via the Internet. Having uploaded
your .nwd file to a web server, this file can then be opened directly from within JetStream. Utilizing
JetStream technology, it will not be necessary for the entire file to be downloaded before navigation can
commence - between 10% and 50% will be sufficient for this, depending on the file structure. (The greater
the hierarchical structure of the model, the closer to 50% will be required for navigation to commence.
Similarly, the lesser the hierarchical structure of the model, the closer to 10% will be required).
To open a file via a URL:
•
Go to File, Open URL...
2.6. Appending Files
JetStream enables you to build up a complex scene from smaller models by appending, or uniting,
multiple model files together, which can be of any type that JetStream Roamer supports. (See Chapter 3,
Converting Files for more detailed information on these file formats and their options).
Each file has its own units and when appending more files to the scene, each file is automatically scaled
to match the units of the first file loaded into the scene. Each file type has a default unit associated with it
that it uses when loading files of that type. You can change this associated unit in the Units tab of the
Global Options dialog (see Section 14.10, “ Units Options ” for more detailed information). However,
once a file is loaded, you can change its unit scaling using the Edit, File Units and Transform function.
See Section 8.10, “ Setting a File's Units and Transform ” for more information.
The combined set of models may be published as a single JetStream .nwd file using the JetStream
Publisher plugin. These models can then be viewed with NavisWorks Freedom™ free viewer. See
Section 4.1, “ Publishing from Roamer ” for more information.
You can also save the combined set of models as an .nwf file. No geometry is saved in this format, but a
list of appended files, along with their path relative to the .nwf file is saved, along with any overrides,
comments, redlines, viewpoints or other JetStream specific information. See Section 2.8, “ Saving Files ”
for more information on saving files.
To append a file
•
Go to File, Append...
or
•
Click Append
on the Standard toolbar.
Note
The standard Open dialog use of Shift and Control keys allows multiple files to be selected and
appended to the current set of models.

2.7. Merging Files
When merging multiple .nwf files, that each comprise the same reference files, JetStream will only load a
single set of the combined models, along with all review markup (such as tags, viewpoints or comments)
from each .nwf file. Any duplicate geometry or markup will be removed when merged. See Section 3.1.1, “
NWF Files ” for more information on .nwf files.
To merge a file:
•
Open the first file to be merged, (see Section 2.4, “ Opening Files ” for information on how to do this).
Then
•
Go to File, Merge...
or
•
Click Merge
on the Standard toolbar.
Finally
•
Browse to and select the file, or files, to be merged.
Note
The standard Open dialog use of Shift and Control keys allows multiple files to be selected and
merged with the currently loaded model.
Merging TimeLiner Data
If a TimeLiner license is available, and two or more merged files contain TimeLiner data, limited merging
can be done with this data. Three scenarios are handled.
•
If the two TimeLiner data sets are identical, then merging of files can occur without issue.
•
If the two TimeLiner data sets are completely unrelated, merging of data in this context will not be
successful
•
If the two TimeLiner data sets contain the same Primary link then the data set with the most recent link
(i.e. the newest file date) is chosen over the other. If the Primary links are different, then the data set
with the highest number of tasks will be used, and links will be re-attached wherever possible.
For more information on TimeLiner, see the TimeLiner book.

File Management
When you have finished reviewing a model or a set of models and are exiting JetStream, you are
prompted to save. When saving to a JetStream .nwf file, only a list with pointers to the files currently
loaded is saved, along with the scene's environment, the current view, clash results (if available) and
viewpoints. If you want to take a snapshot of the scene, including all geometry, then you need to publish
an .nwd file. See Section 2.10, “ Publishing Files ” for information on how to do this.
Saving a file

2.12. Deleting Files
This command deletes the selected files from the scene. It is only available when more than one file is
appended in the scene.
Note
You cannot delete files from within a "published" NavisWorks .nwd file (see Section 2.10, “
Publishing Files ”. You can only delete appended files, whether they were appended manually, or
within an .nwf file.
To delete a file
•
Go to File, Delete File
Note
It is not possible to undo this command.
2.13. Emailing Files
JetStream is a communication tool and the Send feature makes it easy for you to send your current
model along with its viewpoints. The Send command uses your current mail exchange service and will
prompt you to set one up if it cannot find one.
Sending a mail will first save the current working file, so you are guaranteed to always send the latest
review.
To send a file by email from within JetStream
•
Go to File, Send...

or
•
Click Send
on the standard toolbar.
This accesses your mail package and sends the current file as an email attachment.
Receiving 3D Mail
If an .nwf file is received, JetStream will search for the appended files first using the absolute path that the
sender originally saved the file with. This is useful if a team is on a local network and the files can be
found using the Universal Naming Convention (UNC). Otherwise, a team not sharing a server can
organize a project using the same file hierarchy and drive letter and JetStream can find the files this way.
If JetStream is unable to find the files, then the recipient can save the attached .nwf in a directory where
all the appended files are located. The .nwf can then look for these files relative to its own location.
This way, you are able to move a whole sub-directory from your projects directory to a completely new
location. Save the .nwf file in this new place and it will be able to search for the files from here.
2.14. Importing Files
The import option inputs Intergraph PDS review data, including:
•
PDS Tags (.tag)
•
PDS Display Sets (.dst)
It is also possible to import data that has been exported from previous JetStream sessions, including:
•

2.
Select Export model relative to terrain height to put Google Earth in a mode where all heights are
measured from the surface of the ground. When this is off all heights are measured from sea-level.
Note
When positioning a model relative to sea level, the height of the Google Earth reference points
must also be measured relative to sea level. When positioning a model relative to the ground, the
Google Earth reference points must be measured relative to the ground.
Google Earth always places new placemarks at an altitude of zero, irrespective of whether that is
relative or absolute.
3.
Collapse on export allows different levels of collapsing parts of the model hierarchy in the exported
file.
•
None ensures the whole heirarchy is exported
•
All objects collapses everything into one node

Limit number of Polygons should be enabled to restrict the amount of geometry exported into the
output file. Geometry is selected on the basis of taking the most obvious objects in preference to the
fine detail. If the exported file is too large for Google Earth to display, try enabling this and reducing
the number of polygons. View, Scene Statistics in JetStream shows the number of triangles and/or
lines in the current project. By setting a polygon limit you are choosing to export only some of these
items.
Note
Google Earth's ability to handle large numbers of polygons is far more limited than JetStream.
Hence it is worth noting that currently Google Earth will consider 1,000,000 polygons as being a
big model.
5.
The Origin position values are the first pair of reference points on the Google Earth surface, and
must always be defined. The JetStream reference point will always be positioned to exactly overlay
the Google Earth reference point.
Second and Third reference points can be used, and if enabled then the position and orientation of
the model can be more accurately defined.
6.
Use the Import buttons to read-in saved placemark locations from KML files exported from Google
Earth.
The Origin Import button differs slightly from the other two; if the KML file contains multiple
placemarks, this button will offer the user the choice of importing second and third reference points if
available. The other two buttons will only import a single reference point.
7.
The Pick buttons allow the reference point locations to be selected in the main 3D view.
These points must be visible in the main 3D view prior to exporting, as once the KML Options dialog
is open you will not be able to navigate before picking.
Note
You may wish to use View, Split to split the main 3D view enabling you to have separate views of
each reference point.
2.23. Quitting JetStream
Quitting JetStream

Chapter 3. Converting Files
With JetStream Roamer you can open a wide variety of native CAD file types without having to have the
CAD application on your machine. Files read by JetStream include .dwg, .dgn, .dxf and Inventor. For a full
list of CAD files that JetStream can open, please refer to the web site www.navisworks.com
[http://www.navisworks.com]. This site will also explain which entities are read by JetStream and which
are ignored, as well as any object property information that is converted. It is possible to load multiple files
of different formats into the same scene in JetStream and set their units and origins appropriately. There
are also a number of options to help optimize native CAD file reading.
In addition to these native CAD files, JetStream Roamer also reads its own native .nwc (NavisWorks
Cache), .nwf (NavisWorks File review) and .nwd (published NavisWorks Data) file formats.
Some file formats, such as those from Autodesk's Viz and Graphisoft's ArchiCAD cannot be read directly
by JetStream Roamer but there are exporters available to export to the NavisWorks .nwc file format from
these applications. See Section 3.2, “ File Exporters ” for more details.
3.1. File Readers
As well as the NavisWorks file formats, .nwf, .nwd and .nwc, Roamer can open a variety of native CAD
and scanning applications' formats:
•
.dwg
•
Bentley AutoPLANT .dwg, .mdb
•
.dxf
•
.dwf
•
.3ds
•
.dgn
•
.man
•

3.1.1. NWF Files
.nwf files can be saved by JetStream Roamer in order to save a current review of the scene. No geometry
is saved in this format, but a list of appended files, along with their path relative to the .nwf file is saved,
along with any overrides, comments, redlines, viewpoints or other JetStream specific information. .nwf
files are useful when the CAD files are still changing throughout the design period, as the latest files are
loaded each time the .nwf file is opened.
3.1.2. NWD Files
.nwd files are files published by JetStream Publisher and are snapshots of the model at a certain time.
See Section 4.1, “ Publishing from Roamer ” for more information on this.
NWD Options
JetStream allows you to enable and disable geometry compression and select whether the precision of
certain options should be reduced when saving (or publishing) .nwd files. Geometry compression results
in less memory being required and therefore smaller .nwd files.
Setting NWD options
1.
Go to Tools, Global Options, and select the NWD tab.

Cache files (.nwc) are used when reading native CAD files, such as files from AutoCAD or MicroStation.
By default, when JetStream Roamer opens a native CAD file, it first checks in the same directory whether
there is a JetStream cache file present with the same name as the CAD file but with a .nwc extension. If
there is, and this cache file is newer than the native CAD file, then JetStream will open this file instead as
it has already been converted to JetStream format and therefore will open much quicker. If, however,
there is no cache file present, or the cache file is older than the native CAD file, then JetStream will have
to open the CAD file and convert it. At this point, it will by default write a cache file in the same directory
and with the same name as the CAD file, but with the .nwc extension, for speeding up the opening of this
file in future.
See Section 3.2, “ File Exporters ” for more information on why you might want to use the .nwc file
exporters, which CAD applications you can export from and how.
NWC Options
JetStream allows you to enable and disable the reading and writing of cache files.
This describes the default process. The options here enable you to enable and disable the reading and
writing of cache files. For example, you may want to disable reading cache files to ensure that JetStream
converts every native CAD file each time it is read, even though this is a slower process. Also, you may
want to disable the writing of cache files in order to save on disk space and clutter, even though the
cache files are generally many times smaller than the original native CAD files.
Setting NWC options
1.
Go to Tools, Global Options, and select the NWC tab.
The Caching dialog box is displayed.

3.1.4. DWG and DXF Files
JetStream Roamer's .dwg and .dxf file reader uses Autodesk's ObjectDBX™ technology and so is
guaranteed to read all object geometry and information for those third party applications that utilize the
ObjectDBX Framework.
The reader currently supports all surface (shaded) entities (3D faces, rectangular meshes, polyface
meshes, circles, extruded lines and so on), including Proxy Graphics and custom objects such as ACIS
based entities (3D Solid, Region), lines, points and snap points. Complex entities (shapes, dimensions,
text) are not supported. The structure of the drawing is preserved including xrefs, blocks, inserts,
AutoCAD color index, layers, views and active viewpoint. Entities are colored using the AutoCAD Color
Index (ACI), so will match those in an AutoCAD "shaded" view.
There is also an .nwc file exporter for AutoCAD - see Section 3.2.1, “ AutoCAD .nwc Exporter ” for more
details.
Note
The reader supports files from all products based on AutoCAD 2007 and earlier.
Supported Entities
•
All 2D and 3D geometry, including arcs, lines, polylines with non-zero thickness, ACIS objects (regions
and solids), polygon and polyface meshes, 3D faces and surfaces.

whole, whereas if you check this check box, you will be able to select the individual pane and frame.
However, the names of the pane and frame will be based on their color.
5.
From the Default Decimal Units drop-down, choose the type of units that JetStream will use when
opening .dwg and .dxf files that were created with decimal drawing units. Note that .dwg and .dxf files
do not specify the units they were created in. If the units turn out to be wrong, they can be easily
changed using the File Units and Transform function (see Section 8.10, “ Setting a File's Units and
Transform ” for more details).
6.

21. Check the Convert Hidden ADT Spaces check box to perform conversion of space objects that lack
any visible 3D geometry in ADT (for example if they lack floor or ceiling thicknesses). This will result
in corresponding hidden objects appearing in JetStream Roamer. The normal behaviour for space
objects that have visible 3D geometry in ADT is unaffected.
22. The Material Search Paths edit box may contain file paths in a semi-colon separated list that will be
searched for texture files used in Autodesk Architectural Desktop materials. Default Autodesk paths
are automatically searched and need not be entered.

3.1.6. Bentley AutoPLANT Files
Bentley AutoPLANT is based on AutoCAD and as such uses the .dwg file format to store model
geometry. Any settings related to the .dwg file format also affect files from AutoPLANT.
AutoPLANT Object Properties can be stored in external database .mdb files, and JetStream supports
these files through the DataTools functionality. By default JetStream and DataTools are both set up to
support AutoPLANT .dwg and .mdb files, and will be looking for Equipment, Nozzle and Piping Data.

The settings for these three sets of data can be edited by selecting the appropriate item in the list and
clicking on the Edit button. See Chapter 17, DataTools for more information.
For AutoPLANT properties to be loaded correctly an .mdb file must be located in the same directory as
the .dwg file, with the same filename followed by the .mdb extension. If this file exists, JetStream will
automatically pick it up and use it to show appropriate properties in the Properties window.

3.1.7. 3DS Files
3DS is a common file format that is supported by many CAD applications. The JetStream file reader
reads all 2D and 3D geometry as well as texture maps. The hierarchy defined by the keyframe data from
keyframe 0 is preserved, including instancing. Entities are positioned based on keyframe 0.
JetStream Roamer does not read .max files, but instead has exporters for Viz and Max. Entity support is
the same as for the 3ds reader. See Section 3.2.4, “ Viz and Max .nwc Exporter ” for more information.
Textures from .3DS files come through into JetStream Presenter, though you should bear in mind that
.3DS files contain file names in the 8.3 DOS format only and that various formats are not yet supported in
Presenter (see below).
Supported Entities
•
All 2D and 3D geometry
•
Cameras
•
Groups
•
Texture maps in the formats: 8-bit color-mapped, 16-bit and 24-bit true color, uncompressed or Run
Length Encoded .tga, .bmp, .jpg, .lwi (LightWork Image). (Requires a valid JetStream Presenter
license).
•
Colors (from material color, not wireframe color - ambient, diffuse,shininess, transparency and self
illumination)
Unsupported Entities
•
Keyframes (objects are currently taken from keyframe 0)
•
Texture maps in the formats: gray-scale .tga, .tif, .gif, .png.
•
Other maps (e.g. opacity maps, reflections etc.)
•

3.1.8. DGN and PRP Files
JetStream Roamer can read 3D .dgn and .prp files from Bentley's MicroStation, but does not support .cel
files or 2D .dgn files. Reference files and instances of cells are respected and the selection tree reflects
this file structure.
There is also an .nwc file exporter for MicroStation - see Section 3.2.3, “ MicroStation .nwc Exporter ” for
more details.
Note
The reader supports files from MicroStation 95, SE and /J. It does not support MicroStation
Modeller and any versions of MicroStation before 95.
The DGN reader additionally does not support auxiliary coordinate systems.
Supported Entities
•
All 2D and 3D geometry including shapes, complex shapes, meshes, cones, surfaces, B-spline
boundaries, solids, SmartSolids and Feature Solids, lines, arcs and ellipses.

10. Check the Convert References check box if you want to read reference files from the .dgn file.
11. Check the Ignore Unres. References check box if you want to ignore unresolved reference files
from the .dgn file. If this check box is unchecked, then you will be presented with a dialog to find any
unresolved reference files at run time.
12. Check the Use Level Symbology check box if you want to use the level symbology from
MicroStation so that items in JetStream take their color from level rather than the default element
color in MicroStation.
13. MicroStation has the concept of a “global origin”, which is where (0, 0, 0) is located (assuming there
are no active ACSs). Changing this global origin in MicroStation doesn't actually move anything; it
simply changes the reporting of coordinates. However, when attaching references in MicroStation,
you can tell it to align global origins.
Check the Align Global Origins check box if you want to use this functionality when loading DGN
files into JetStream. When two DGN files are appended together with this check box checked, their
global origins will be in the same place.
14. Check the Use Materials check box if you want to use MicroStation's materials in place of its colors
in JetStream. If you choose not to export materials, JetStream will assign the same colors as in the
MicroStation scene. Assigning materials will assign the same textures, diffuse, ambient and specular
colors to the elements as in the MicroStation scene.
Note
For MicroStation materials to be read into JetStream Roamer, a valid Presenter license is
required.
15. Enter a semi-colon separated list of paths in Material Search Paths that the reader will search in for
MicroStation palette (.pal) and material (.mat) files in order to convert its materials.
16. Check the Convert PDS Data check box if you want to read object information from Intergraph's
Plant Design System™ while reading the .dgn files. PDS information is read from Intergraph's .drv
files. JetStream looks for a .drv file with the same base name as the .dgn file in the same directory.
17. Check the Convert TriCAD Data check box if you want to read object information from Triplan's

TriForma™ while reading the .dgn files.
19. Enter a semi-colon separated list of paths in TriForma Dataset Search Paths that the reader will
search for Triforma data set files. User defined datasets will need their directories adding to this list.
20. Enter a View Number if you want to use a specific view for loading. The loader will use the level
visibility of this view when converting items. If you want to use the first active view, set this value to 0.
21. Click OK to set these options or Cancel to exit the dialog without setting them.
3.1.9. MAN Files
JetStream Roamer can read .man files from Informatix's MicroGDS™ version 6.0 or later. MicroGDS™
projects are not supported. The workaround is to first export the desired project window as a .man file.
MicroGDS Renderer materials are shown in their flat-shaded colors in JetStream Shaded display. In Full
Render or Presenter rendering, the full shaders are used. Only the standard LightWorks shaders are
available - those which are unique to MicroGDS are not available inside JetStream - a compromise is
made for shaders which are not available inside JetStream.
•
height band color shader is treated as plain grey
•
wrapped random color shader is treated as a plain color using the flat-shaded color from MicroGDS.
•
wrapped stencil transparency is ignored
•
undulate, wrapped brick, wrapped grid and wrapped ripple displacement shaders are ignored
•
object axis texture space is equivalent to the JetStream Box texture space
•
auto axis and object xy axis texture spaces are treated as a Box texture space
•
grid background is treated as a plain background using the background color - no grid lines will
show.
•
Foreground and Environment shaders are ignored.
•
All other shaders, as of MicroGDS 7.2, are correctly imported into JetStream.
•
Note that MicroGDS materials are specified in millimetres, and are converted into metres to make
JetStream materials, dividing distance parameters by 1000. Windows with Perspective Views are read
into JetStream as View objects.
Windows with Perspective Views are read into JetStream as Saved Viewpoints.
Supported Entities
•
Clump primitives.
•
Line primitives. The color of line primitives is determined by the first phase in which they appear in the

Check the Convert attributes box to attempt to load attribute files.
5.
Check the Search all attribute files box to affect how attribute files are looked for and loaded.
If unchecked, the reader firstly looks for an attribute file with the same name as the RVM file in the
same directory, followed by all attribute files contained within any subdirectory with the same name
as the RVM file. The attribute file extensions searched are listed in the Attribute file extensions
box.
If the Search all attribute files box is checked, the reader looks for a file using the method above,
but also tries all attribute files in the same directory as the RVM irrespective of filename.
6.
Attribute file extensions lists all extensions that will be considered for attribute conversion. This can
be edited and added to where necessary.
Note
Using Dump Attributes may not bring through all attribute data. If more than one database is
used in the project, it is recommended that attributes be exported using the Datal method.
7.
Check the Generate texture coordinates check box to create texture coordinates for each point in
the model. This will affect how textures are applied to the geometry.
8.
Check the Keep empty groups check box to keep any groups in RVM file that do not contain
geometry. If unchecked, such groups will be discarded.
Note
RVM files do not contain color information beyond a color number on each scene element. As
these colors are customisable JetStream provides a color definition file to allow easy color
personalisation.
Two examples of this file are located in the RVM subdirectory inside the main JetStream install
directory:
colors.txt - these are a set of default Review™ colors (this file is used by JetStream).
PDMS_colors.txt - these are a set of the default PDMS™ colors (example file - this is not used
by JetStream)
To use a different set of colors, copy the colors.txt file into one of the JetStream search
directories, and edit the contents accordingly. The RVM Reader will search these directories on
startup and use the first colors.txt file it finds. See Section 14.12, “ Search Directories ” for more
information
9.
Load RVS file should be checked if a corresponding RVS file should be searched for and loaded on
loading the RVM file. To work correctly, the RVS file must have the same name as the associated
RVM file, but with the .rvs extension.
10. RVS transparencies as materials should be checked if it is required to respect transparencies
coming through from the RVS files, treating them as materials within JetStream. If this is left
unchecked, RVS transparencies are ignored.

3.2. File Exporters
Cache files can in some cases be exported from the CAD application itself. Currently, they can be written
directly from AutoCAD, Revit, MicroStation, ArchiCAD and Viz. There are two reasons you may want to
use cache files in this way:
1.
JetStream Roamer cannot read the native CAD file directly, in the case of ArchiCAD, Viz and Revit,
but you wish to view the files created in these applications.
2.
You wish to get a better quality file into JetStream. Although the direct file readers are adequate the
majority of the time, the exporters can get a better quality. So if you are missing some items, or some
items are being read wrongly by reading the native CAD files directly, then try exporting to an .nwc
file and reading this into JetStream Roamer instead.
There are .nwc file exporters for the following CAD applications:
•
Autodesk's AutoCAD
•
Autodesk's Revit
•
Bentley's MicroStation
•
Discreet's Viz and Max
•
Graphisoft's ArchiCAD
3.2.1. AutoCAD .nwc Exporter
JetStream Roamer comes with ARX plugins for any AutoCAD™ based product, such as Architectural
Desktop™, that enable you to export an .nwc file directly from the CAD application in which it was
created. As long as AutoCAD is already installed on the computer when JetStream is installed, the ARX
plugin is installed with JetStream on a Custom Install or Full Install and ready for use.
Note
If you install AutoCAD after JetStream, then install JetStream again, choosing the Custom Install
option and choose the relevant version of AutoCAD. The JetStream installer will find the right
place for the plugin and set up all relevant registry entries for you.
The .nwc exporter is available for any AutoCAD based product between AutoCAD 14 and 2007
releases.
You can also publish .nwd files directly from AutoCAD™ if you have the Publisher plugin. For more
76

details, refer to Section 4.2, “ Publishing from AutoCAD ”.
Exporting .nwc files from AutoCAD
1.
Type nwcout at the command line.
2.
The standard Windows™ Save As dialog is displayed, so choose the location and name of the .nwc
file to be exported.
3.
Click OK to export the file or Cancel to return to AutoCAD without exporting it.
See Section 3.1.4, “ DWG and DXF Files ” for what entities are and are not supported by the AutoCAD
exporter.
If, on typing nwcout at the command line, you get an error, you probably have to load the ARX plugin
manually. You should only have to do this once.
Loading the NavisWorks ARX Plugin
Loading the ARX plugin manually
1.
Type ARX (followed by return) at the command line.
2.
Then type the letter l (followed by return) at the command line, for "Load".
3.
The Select ARX file dialog will be displayed, so browse to the ARX plugin. By default, for AutoCAD
R14, this will be C:\Program Files\NavisWorks 5\NWExport\nwexport.arx, for AutoCAD
2000
based
applications,
this
will
be
C:\Program
Files\NavisWorks
5\NWExport2000\nwexport2000.arx, for AutoCAD 2004 based applications, this will be
C:\Program Files\NavisWorks 5\NWExport2004\nwexport2004.arx, and so on.
4.
Click OK to load the ARX plugin.
5.
You should now be able to use the nwcout command from AutoCAD to export an .nwc file.
The JetStream Partial Menu for AutoCAD
If you prefer to work from menus, there is a partial menu available to run this export command from, along
with the other JetStream ARX plugins.
Loading the NWExport partial menu
1.
At the command line, type menuload (followed by return).
2.
The Menu Customization dialog will be displayed, so change the Files of type to Menu Template
(*.mnu) and browse to the partial menu. By default, for AutoCAD R14, this will be C:\Program

AutoCAD 2004 based applications, this will be C:\Program
Files\NavisWorks
5\NWExport2004\LwNw_Export.mnu, and so on.
3.
Click Load and then Yes to the dialog that appears.
You should now have a NavisWorks menu just before the Help menu and this will be reloaded into future
AutoCAD sessions. This menu contains 4 items:
•
Publish .nwd
See Section 4.2, “ Publishing from AutoCAD ” for more details.
•
Export .nwc
See Section 3.2.1, “ AutoCAD .nwc Exporter ” for more details.
•
NavisWorks Export Options
See Section 3.2.1, “ AutoCAD .nwc Exporter Options ” for more details.
•
Navigator
See Section 3.3.1, “ NavisWorks Navigator for AutoCAD ” for more details.
AutoCAD .nwc Exporter Options
Available from the NavisWorks menu, or by typing nwopt at the command prompt, this enables you to
configure various elements of the exported file to your choosing.
See Section 3.1.4, “ DWG and DXF File Reader Options ” for details on what each of the options does.
Once you have set the options, future exports of .nwc and publishes of .nwd files will use these settings.
3.2.2. Revit .nwc Exporter
JetStream Roamer cannot read native Revit files directly, however support for both Revit Building and
Revit Structures can be achieved through exporting a JetStream .nwc cache file, which can then be read
into Roamer.
Note
The Microsoft .NET Framework is not installed by JetStream and must be installed for JetStream
and Revit to work correctly on the same machine. If these components are not installed an error
message will be displayed when Revit is started. The version of .NET Framework to install is
dependent upon the version of Revit being used.

3.2.3. MicroStation .nwc Exporter
JetStream Roamer comes with MDL plugins for MicroStation™ 95, SE, /J and v8 that enable you to
export .nwc files directly from the CAD application in which it was created. As long as MicroStation is
already installed on the computer when JetStream is installed, the MDL plugin is installed with JetStream
on a Custom Install or Full Install and ready for use.
Note
If you install MicroStation after JetStream, then install JetStream again, choosing the Custom
Install option and choose the relevant version of MicroStation. The JetStream installer will find
the right place for the plugin and set up all relevant registry entries for you.
You can also publish .nwd files directly from MicroStation™ if you have the Publisher plugin. For more
details, refer to Section 4.3, “ Publishing from MicroStation ”.
There are two steps to exporting .nwc files from MicroStation - first you have to load the MDL plugin into
MicroStation and then you have to export the file.
Loading the NavisWorks MDL Plugin
Loading the NWExport MDL plugin manually
1.
Go to the Utilities, Key-in dialog box to load the application manually.
2.
Type "mdl load nwexport5" (without the quotes) and press return.
If you regularly export .nwc files from MicroStation, then you will not want to load the NWExport plugin
manually each time, so do the following:
Loading the NWExport MDL plugin automatically
1.
Go to Workspace, Configuration.
2.
Choose Design Applications under Category.
3.
Choose NWEXPORT5 under Available Applications.
4.
Click Add and confirm that you want NWExport added to your default configuration.
5.
MicroStation will then automatically load NWExport in future sessions.
6.
Click OK.

Once NWExport plugin is loaded, you can export to .nwc using the nwcout command from the key-in
command line.
Exporting .nwc files from MicroStation
1.
Type nwcout at the key-in prompt.
The MicroStation export dialog is displayed.
2.
Select the location and filename you want to export to. The exporter will make a guess at a suitable
filename for you.
3.
Select the view number you wish to the model to be exported from.
4.
Click on the Options button if you want to change the export configuration. See Section 3.2.3, “
MicroStation .nwc Exporter Options ” for more information on these options.
5.
Click OK to export the file or Cancel to return to MicroStation without exporting it.
Note
MicroStation can also be customized to add NWExport commands to the menu bar using the
Workspace, Customize dialog.
See Section 3.1.8, “ DGN and PRP Files ” for what entities are and are not supported by the MicroStation
exporter.

Converting Files
JetStream colors are derived from either MicroStation cell colors or MicroStation materials, depending on
the export options set during nwcout. The appearance of objects in Publisher will match the appearance
of a MicroStation shaded render.
The view number chosen for export determines the initial view in JetStream, whether level symbology is
used and which levels are hidden.
Note
The exporter only exports from 3D dgn files - 2D files are not supported.
Quickly exporting files
If you want to export the current design file quickly, you can use the batchnwcout key-in. This will not
display the export dialog box, and it will not prompt you to overwrite any existing files. It simply replaces
the design file extension (usually .dgn) with .nwc when exporting.
Exporting from the command line
The MicroStation exporter can also be run from the command line. This is useful when you want to export
lots of files using an automated script.
It uses the msbatch.bat batch file that comes with MicroStation. To export a file from the command line,
you must first ensure that the MicroStation program directory is in your PATH environment variable.
The format of the command line exporter is:
msbatch nwexport5 [-f] FILE [OUTPUT]
FILE is the name of the DGN file you want to export. This is the only required option. If you want, you can
specify the name of the output file with the OUTPUT argument.
The command line exporter will only convert a file if it has changed since the last time you exported it.
This is useful for speeding up exporting of a large number of files. If you want to force the exporter to
re-export a file, use the -f option.
If the exporter encounters any problems, it will produce an error log in a file called nwdout.err.
MicroStation .nwc Exporter Options
Available from the NWExport dialog box, this enables you to configure various elements of the exported
file to your choosing.
See Section 3.1.8, “ DGN File Reader Options ” for details on what each of the options does.
Once you have set the options, future exports of .nwc and publishes of .nwd files will use these settings.
3.2.4. Viz and Max .nwc Exporter
While JetStream Roamer cannot directly read .max files, there is a plugin for Viz versions 3, 4 and 2005
and Max versions 5 and 6 that will export the model to an .nwc cache file that can then be read into
Roamer. Viz will be outlined here, although the process is exactly the same for Max.
As long as Viz is already installed on the computer when JetStream is installed, the plugin is installed with
JetStream on a Custom Install or Full Installand ready for use.

3.2.5. ArchiCAD .nwc Exporter
While JetStream Roamer cannot directly read ArchiCAD files, there is an addon for ArchiCAD v6.5, v7.0,
v8.0 and v9.0 that will export the model to an .nwc cache file that can then be read into Roamer. The
export add-on for ArchiCAD is available from both the 2D and 3D windows. All standard ArchiCAD
elements and library parts can be exported as long as they have a 3D representation, and any others will
be ignored. The exporter will save both standard materials and custom GDL script materials.
When saving from the 2D window the current story will be exported by default. An option may be set so
that the whole model will be exported. A default view will be determined from the bounding box of the
model.
When saving from the 3D window the view will become the default JetStream view (including window
settings such as cutaway planes).
Note
Only visible layers will be exported.
Cutaway plane settings does not set the JetStream section plane, but exports items that are
physically reduced by the plane. It is advised to turn off the Enable library part instancing option
since all instances will show the same sectioning as the original item (usually the first library part
in the file), and this may lead to unexpected effects.
Exporting an .nwc file from ArchiCAD
1.
With a model loaded choose File, Save As. An options dialog will allow you to change settings
before the export process begins.
2.
Select "NavisWorks (*.nwc)" as the file type and type in a file name.
3.
Click OK to advance to the options dialog.
4.
Click OK on the options dialog to export the file or click Cancel to return to ArchiCAD without saving
anything.

ArchiCAD .nwc Exporter Options
The export options appear after choosing OK from the File, Save As menu.
Setting the ArchiCAD exporter options
1.
Check the Export GUIDs check box if you want to attach a Globally Unique IDentifier as a property
to each item in the model. This is mainly useful for clash detection to track clashes.
2.
Check the Enable library part instancing check box if you want to make instances of library parts
rather than creating new items. This is only possible when multiple library part elements within the
ArchiCAD model have exactly the same properties. Instancing these parts means a smaller .nwc file,
and shorter export times.
3.
Library parts defined in GDL scripts may have a number of user defined custom parameters. Check
the Export library part parameters check box if you want to save library part parameter values as
item properties in JetStream.

Check the Export current story only check box if you want to only export the current story.
Otherwise all stories will be exported. This is only applicable to exports from 2D views, as 3D views
will export everything contained within the view.
3.3. CAD Previewing
JetStream Roamer comes with plugins for AutoCAD 2000 and above and Viz and Max for quick and
simple previewing of the models that are being built in those applications. These previews help in setting
up viewpoints within the CAD application, and also for previewing what the model will look like inside
NavisWorks Freedom™ once published.
3.3.1. NavisWorks Navigator for AutoCAD
JetStream Roamer comes with an ARX plugin for products based on AutoCAD 2000™ and above that
enables you to walk through your model in real time inside a dockable dialog in the AutoCAD interface.
Not only that, but it enables you to easily import and export viewpoints between Navigator and AutoCAD
so that you can quickly and easily get to where you want in the model.
Note
NavisWorks Navigator is not available for AutoCAD R14 or previous versions.
If you install AutoCAD after JetStream, then install JetStream again, choosing the Custom Install
option and choose the relevant version of AutoCAD. The JetStream installer will find the right
place for the plugin and set up all relevant registry entries for you.
Navigating AutoCAD models in real time
1.
Type nwnavigator at the command line, or go to NavisWorks, Navigator.
The Navigator dockable dialog is displayed.

Navigator is very similar to NavisWorks Freedom™ (see Section 4.4, “ Freedom ”, except that it has
three extra buttons on the interface.
3.
Click on the NavisWorks™ button
to update the Navigator window with what's in the AutoCAD
window.
Note
The Navigator window is not updated automatically when the AutoCAD model changes, so you
have to click on this button manually every time you want to navigate around the latest model.
4.
Click on the Export Viewpoint button
to update the current AutoCAD viewpoint with that in the
Navigator window.
5.
Click on the Import Viewpoint button
to update the Navigator viewpoint with that in the current
AutoCAD window.
If, on typing nwnavigator at the command line, you get an error, you probably have to load the ARX
plugin manually. See Section 3.2.1, “ Loading the NavisWorks ARX Plugin ” for details on how to do this.
You should only have to do this once.
If you prefer to work from menus, there is a partial menu available to run this command from, along with
the other JetStream ARX plugins. See Section 3.2.1, “ The JetStream Partial Menu for AutoCAD ” for
more information on how to use this menu.

Chapter 4. Publishing
JetStream Roamer has an optional plugin called JetStream Publisher, that enables you to take a
snapshot of the model at a certain time for issuing for use by other members of the design team, who
perhaps are not CAD users, but who have a need to view the 3D model. NWD files published by
JetStream Publisher can be read by JetStream Roamer for full design review, or by the NavisWorks
Freedom free viewer for simple real time walk through. You can publish files directly from JetStream
Roamer or by exporting from AutoCAD™ or MicroStation™.
4.1. Publishing from Roamer
JetStream Publisher .nwd files are files published by JetStream Publisher and are snapshots of the model
at a certain time.
Publishing a NavisWorks .nwd File

3.
Password gives you the opportunity to password protect nwd files. On clicking OK, you will be asked
to re-enter the password to ensure you have not mis-typed it.
4.
If the Display at password checkbox is checked, this will force JetStream or NavisWorks Freedom
to display the publication entries in a dialog on asking for the password so that the recipient is able to
know whose password to enter.
5.
If the Expires checkbox is checked, this will "time-bomb" the file so that it will not be openable in
JetStream or NavisWorks Freedom™ after the date set.
Note
Evaluation copies of JetStream can publish .nwd files, however these files will have a
"time-bomb" set to the same expiry date as the evaluation software. To remove the expiry date
from an .nwd file created by an evaluation copy, you must re-publish the file with a full JetStream
Publisher license.
6.
If the May be re-saved checkbox is checked, this will allow JetStream to re-publish the file with new
publication information. If this checkbox is not checked, the publication information in the nwd file will
never be changeable.
7.
The checkbox Display on open, if checked, will force JetStream to display the publication entries in
a dialog on opening the file.
8.
If the Embed Textures checkbox is checked, all textures will be embeded in the published file;
separate texture files will no longer be created.
9.
The Embed Database Properties check box, if checked, force any properties accessed via an
external database to be embedded in the NWD. No database links will be stored in the file from this
point on.
10. The checkbox Prevent Object Property Export, if checked, will stop any native CAD package object
properties from being exported into the published file.
11. Click OK to go to the File Save dialog where you can type in the name and location of the published
file, or Cancel to return to JetStream.
Note
When publishing a scene, any RPCs included in that scene are not published to the
Presenter_maps directory or embedded in the NWD file. The size of the files and the fact that
most are licensed currently prohibits this.
4.2. Publishing from AutoCAD ™
JetStream Publisher comes with ARX plugins for any AutoCAD™ based product, such as Architectural
Desktop™, that enable you to publish an .nwd file directly from the CAD application in which it was
created.
Note
If you install AutoCAD after JetStream, then install JetStream again, choosing the Custom Install

to be copied to a new location, perhaps a CD or a network location, which other people can then
have access to. An NWD file could be included to make it very simple to view the model. People
would simply need to double-click on the Freedom executable and open the accompanying model
file from that location.

Chapter 5. Navigating
JetStream enables intuitive and interactive navigation around your 3D models at a guaranteed frame rate.
The nine navigation modes give you complete flexibility to navigate around the model in real time. In
addition to these navigation modes, there are selection and measuring tools that further facilitate the
interrogation of model data.
The navigation tools allow you to do things such as focus on objects and change the view parameters.
There are also options to look from predefined views, set the world up vector to a direction different than
the one brought through from the CAD model.
The tilt bar enables you to tilt the model, or the camera (depending on if the navigation mode is
camera-centric or model-centric) and has the same effect as spinning the wheel on a mouse. Two
thumbnail views also give you a good overall view of the scene, allowing you to see whereabouts you are
in the whole model and quickly jump from one end to the other.
5.1. Navigation Modes
There are nine navigation modes to control how you move around the main navigation view - six
camera-centric modes and three model-centric modes. In a camera-centric mode, the camera moves
within the scene, whereas in a model-centric mode, model moves inside the scene. For example, the
Orbit and Examine modes essentially do the same thing, except that Orbit moves the camera around
the focal point and Examine moves the model around the focal point. Movement in each mode is based
on the cursor keys, the Shift and Control keys and mouse drags. The mouse wheel is also supported,
allowing quick and easy zooming or tilting, depending on the current navigation mode.
Note
Dragging with the left mouse button while holding down the Control key performs the same
actions as dragging with the middle mouse button, which is useful if you only have a two-button
mouse.
The Shift and Control keys modify the movement, for example holding down Shift in Walk mode speeds
up movement, and holding down Control in this mode, glides the camera left/right and up/down.
Note
Gliding the camera is opposite to panning the model. Gliding is a camera-centric motion and
panning is a model-centric motion.
Right clicking on any item in the main navigation view or selection tree displays a context menu that
shows a list of commands relevant to a particular item.
The Navigation Mode toolbar also includes the Select tools, as they are mutually exclusive to navigation
just as redlining and measuring are. See Section 6.2.1, “ Select Mode ” for more information on the
selection tools. Below is shown the Navigation Mode toolbar and the navigation modes available:

customizing it (see Section 14.3, “ Customizing toolbars ”).
5.3. Viewing Everything
This function dollies and pans the camera so that the entire model is in view, which is very useful if you
get lost inside a model or lose it completely.
Sometimes on doing a View All, you seem to just get a blank view. This is usually because there are
items that are very small in comparison to the main model located a long way away from the main model.
In these cases, it is best to click on an item in the selection tree and do a View Selected to at least find
your way back to the model before trying to figure out which items are "lost".
To view everything
•
Go to Viewpoint, Navigation Tools, View All.

Note
Orthographic cameras are not available with Walk and Fly navigation modes.
5.8. Collision Detection
This function defines you as a collision volume - a 3D object that can navigate around and interact with
the model, obeying certain physical rules that confine you within the model itself. In other words, you have
a mass and as such, cannot pass through other objects, points or lines in the scene.
You can walk over, or climb over objects in the scene that are up to half the height of the collision volume,
thus allowing you to walk up stairs, for example.
The collision volume, in its basic form, is a sphere (with radius = r), that can be extruded to give it height
(with height = h >= r). See diagram below:
111
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
Navigating
The dimensions of the collision volume are user definable settings for the current view or as a global
option. See Section 10.5, “ Editing Viewpoints ” and Section 10.6, “ Viewpoints Options ” for more
information.
Collision detection is only available when in either the walk or fly navigation mode.
To activate collision detection:
•
In Walk or Fly navigation mode, go to Viewpoint, Navigation Tools, Collision Detection
or
•
Click Collision Detection
on the Navigation Tools toolbar.
or
•
Press D to toggle collision detection on/off.
Note
When Collision Detection is turned on, rendering prioritization is changed so that objects around
the camera or avatar are displayed with much higher detail than normal. The size of the region of
high detail is based on collision volume radius and speed of movement (needing to see what is
about to be walked into).
5.9. Gravity
This function only works in connection with collision detection.
Where collision detection gives you mass, gravity gives you weight. As such, you (as the collision volume)
will be pulled downwards whilst walking through the model scene (gravity is only available when in the
walk navigation mode).
This allows you to walk down stairs, for example, or follow terrain.
To activate gravity:
•
In the Walk navigation mode, go to Viewpoint, Navigation Tools, Gravity
or
•
Click Gravity
on the Navigation Tools toolbar.
or

•
Press G to toggle gravity on/off.
5.10. Crouching
This function only works in connection with collision detection.
When walking around the model with collision detection activated, you may encounter object that are too
low to walk under, a low pipe for example. This function enables you to crouch under any such objects.
With crouching activated, you will automatically crouch under any objects that you cannot walk under at
your specified height, thereby not impeding your navigation around the model.
If however, you are using collision detection to identify areas of the model that you cannot walk under,
(again, using a low pipe for example) then there is also a temporary crouch function to allow navigation to
proceed once the obstacle has been identified.
To activate crouching:
•
In the Walk or Fly navigation mode, go to Viewpoint, Navigation Tools, Crouch
or
•
Click Crouch
on the Navigation Tools toolbar.
or, if you only want to temporarily crouch
•
Hold down the Space bar to turn crouching on. Releasing it will turn it off again.
5.11. Third Person View
This function allows you to view from a third person perspective.
When third person is activated, you will be able to see an avatar which is a representation of yourself
within the 3D model. Whilst navigating you will be controlling the avatar's interaction with the current
scene.
Using third person in connection with collision detection and gravity makes this a very powerful function,
allowing you to visualize exactly how a person would interact with the intended design.
User definable settings are available for the current view and as global options, including avatar selection
and dimensions and third person positioning. See Section 10.5, “ Editing Viewpoints ” and Section 10.6, “
Viewpoints Options ” for more information.
To view in third person:

or
•
Press T to toggle third person view on/off.
Note
When Third Person mode is turned on, rendering prioritization is changed so that objects around
the camera or avatar are displayed with much higher detail than normal. The size of the region of
high detail is based on collision volume radius, speed of movement (needing to see what is about
to be walked into) and the distance of the camera behind the avatar (in order to see what the
avatar is interacting with).
5.12. Straighten
This function straightens the camera to align with the world up vector when it is already close to the world
up vector.
To straighten the camera
•
Go to Viewpoint, Navigation Tools, Straighten
or
•

5.16. Thumbnail Views
Thumbnails are useful to get an overall view of where you are in the whole scene and to quickly move the
camera to a location in a large model. There are two thumbnails available in JetStream so you can have
one showing a section and another showing a plan view if you wish. The thumbnails show a fixed view of
the model, with a triangular marker representing your current viewpoint. This marker moves as you
navigate, showing the direction of your view. The marker may also be dragged by holding the left mouse
button over it and dragging to move the camera in the main navigation view.
Note
The marker changes to a small dot when the thumbnail view is in the same plane as the camera
view.
To turn on the plan thumbnail:
•
Go to View, Control Bars and select Plan Thumbnail.
or
•
Click Plan Thumbnail
on the Workspace toolbar.
The Plan View thumbnail is displayed

Click Section Thumbnail
on the Workspace toolbar.
By default the Section Thumbnail shows the view from the front of the model and the Plan Thumbnail
shows a plan view. The thumbnail view can be manipulated by right clicking on the view. You can select
from the following options: Look From, Edit Viewpoint, Update Viewpoint, Lock Aspect Ratio and
Refresh.
Manipulating a thumbnail's view
1.
Right click anywhere in the thumbnail to open the context menu.
2.
Use the Look From menu item and choose from Top, Bottom, Front, Back, Left or Right to set the
thumbnail view to any of these pre-set viewpoints. You can also choose Current Viewpoint to set
the thumbnail view to the active navigation viewpoint.
3.
Choose Update Current Viewpoint to set the current active navigation viewpoint to be the same as
that of the thumbnail.
4.

Viewpoint dialog (see Section 10.5, “ Editing Viewpoints ” for more information on this).
5.
Choose Lock Aspect Ratio if you want the aspect ratio of the thumbnail to match that of the main
navigation view and remain matching even when the thumbnail dialog is resized. This will usually
give gray strips either to the top and bottom, or to either side of the thumbnail view. See Aspect Ratio
for more information on aspect ratio.
6.
Choose Refresh to redraw the thumbnail based on the current setting. Thumbnail drawing uses
software OpenGL and so can take a couple of seconds for large models.
5.17. Using a SpaceBall
Note
The term SpaceBall is used as a generic term for all 3D motion controllers from 3Dconnexion™,
including the SpaceBall, SpaceMouse and SpaceTraveler.
A SpaceBall can be used as an alternative to the mouse to move around the main navigation view. The
behaviour of the SpaceBall corresponds to the currently selected Navigation Mode. If no mode is selected
on the Navigation Mode toolbar or if the selected mode is not a valid mode for the SpaceBall, then a
default navigation mode will be used. This enables the user to navigate with the SpaceBall whilst
performing other operations with the mouse. The default navigation mode can be set in the Global
Options dialog.
The speed of navigation is sensitive to the amount of force applied to the SpaceBall. However, the user
can also adjust the speed of translation and rotation by applying a factor to each of these in the Global
Options dialog. These options are offered in addition to the adjustments that can be made using the
Control Panel for the device which is supplied by the SpaceBall manufacturer with the installation.
Setting the SpaceBall behaviour

Chapter 6. Selecting Items
With large models it is potentially a very time consuming process to select items of interest. JetStream
makes this a much simpler task by providing a range of functions for quickly selecting items both
interactively and by searching the model manually and automatically. The main groups of functionality
concerned with selecting items are:
•
The selection tree
•
Interactive selection
•
Selection sets
Also connected with selecting items is finding items, which is covered in Chapter 7, Finding .
In JetStream there is the concept of an active selection set (the currently selected items, or the current
selection) and saved selections sets. Selecting and finding items makes them part of the current
selection, so you can hide them or override their colors. At any time, the current selection can be saved
and named for retrieval in later sessions.
6.1. Selection Trees
The selection tree is a tabbed control bar which displays a variety of hierarchical views of the structure of
the model, as defined by the CAD application in which the model was created.
121
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
Selecting Items
By default there are four tabs, called Standard, Compact, Properties and Sets:
•
"Standard" displays the default tree hierarchy, including all instancing. The contents of this tab can be
sorted alphabetically by right-clicking on any item in the tree and selecting Scene->Sort. It is not
possible to undo this action.
•
"Compact" displays a simplified version of the "Standard" hierarchy, omitting various items. You can
control the level of complexity of this tree using the Select options (see Section 6.5, “ Selection
Options ” for more information).
•
"Properties" displays the hierarchy based on the items' properties. This enables simple manual
searching of the model by item property. See Chapter 7, Finding for a much more powerful way of
searching the model for items with certain properties.
122
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
Selecting Items
•
"Sets" simply shows the same view as the selection sets control bar.
Naming of items reflects the names from the original CAD application, wherever possible.
There are several different tree icons representing the types of item that make up the structure of a
model:
A model, such as a drawing file or design file.
A layer or level.
A group, such as a block definition from AutoCAD or cell definition from MicroStation.
An instanced group, such as an inserted block from AutoCAD or cell from MicroStation. If in the
imported file the instance was unnamed, JetStream names the instance to match its child's name.
An item of geometry, such as a polygon.
An instanced item of geometry, such as an instance from 3D Studio.
A composite object. A single CAD object that is represented in JetStream by a group of geometry
items.
A search. Behind the scenes, JetStream is searching the model for all items with a property of this
type and sets up the find specification to repeat this search if the selection set is saved. See Section 6.3, “
Selection and Search Sets ” for more information on this.
Each of these item types can be Hidden (gray), Unhidden (dark blue) or Required (red).
Note
If a group is selected as Hidden or Required then all instances of that item will be hidden or
required. If you wish to operate on a single occurrence of an item then you should make the
instanced group (the level above, or the "parent", in the hierarchy) Hidden or Required.
You can use the selection tree in combination with the main navigation window to select items into the
current selection, which is highlighted in both the selection tree and the main navigation window.
Note
Using the Shift and Control keys while selecting items in a selection tree will do the standard
Windows™ multiple selection: Control allows multiple selection item by item and Shift allows
multiple selection between the first and last items selected.
If you have the Clash Detective plugin, the selection trees will be used for selecting items for the clash
tests.
The selection trees are also used inside the Find Items control bar for the ability to refine your searches
better. See Section 7.2, “ Finding Items ” for more information.
Note
Additional customised selection tree tabs can be added by using the JetStream API.

Selecting Items
6.2. Interactive Selection
JetStream provides several methods to interactively select items into the current selection. You can use
the tabs in the selection tree, select items in the main navigation window with select and select box
modes and you can select other items with similar properties to an existing selection using the selection
commands.
Note
Right clicking on any item in the tree view or main view temporarily selects the item click on and
displays a context menu. You can click on the topmost menu item to permanently select the item.
6.2.1. Select Mode
As standard, this mode is mutually exclusive to the navigation modes so that when you are selecting, you
cannot navigate and vice versa.
Note
When using a SpaceBall in conjunction with the standard mouse control, the SpaceBall can be
configured for navigation and the mouse for selecting. See Section 5.17, “ Using a SpaceBall ” for
more information.
Select mode allows you to click on an item in the main navigation window to select it. Once a single item
is selected, its properties will be shown in the Properties control bar.
You can select multiple items in the main navigation window using the familiar Windows™ methods of
holding down the Control key while selecting items. This will add them to the current selection.
Alternatively, if the items are already in the current selection, holding down Control while selecting them
again will remove them from the current selection.
Holding the Shift key whilst selecting items in the main navigation window will cycle through the selection
resolution, allowing you to get more specific with your selections. See Selection Resolution for more
information on this.
To select an item
•
Go to Viewpoint, Navigation Mode, Select
or
•
Click Select
on the Navigation Mode toolbar.
6.2.2. Select Box Mode
This mode, which can be used in conjunction with the normal select mode allows you to drag a box in the
main navigation window to select multiple items at once. This mode is also mutually exclusive to the
navigation modes so that when you are selecting, you cannot navigate and vice versa.
Dragging the box will select all items within the box. Holding down the Shift key while dragging the box
will select all items within and that intersect the box.

•
Go to Viewpoint, Navigation Mode, Select Box
or
•
Click Select Box
on the Navigation Mode toolbar.
6.2.3. Selection Commands
Selection commands enable you to quickly alter the current selection using logic. You can select multiple
items based on the currently selected items' properties, or quickly invert the set, select everything or
nothing.
Selecting items with selection commands
1.
Go to Edit, Select
2.
Choose the required selection command.
Standard selections are:
•
Select All
All items contained within the model are selected.
•
Select None
Deselects everything in the model.
•
Select Invert
Every selected item becomes deselected and vice versa.
•
Selection Sets
Provides you with options to save and recall sets. See Section 6.3, “ Selection and Search Sets ”.
•
Select Multiple Instances
Selecting an item then selecting Multiple Instances will select all instances (sometimes called
insertions) of that geometry group that occur in the model.

Selecting Items
•
Select Same Name
Every item with the same name as the selected item will also be selected.
•
Select Same Type
Every item of the same type as the selected item will also be selected.
•
Select Same (property)
Every item with the same property as the selected item will also be selected. The property can be
anything from Material, Hyperlink or any other searchable property attached to the item.
Note
Selecting Same (property) works by comparing items' properties. If you have multiple items
selected when you perform a selection command of same name or type etc., all the types, names
and properties of the items in the current selection are compared with all items properties in the
scene. Those matching any of the current items selected will be selected.
6.3. Selection and Search Sets
Selection sets are useful for saving a group of items that you might want to regularly perform some action
on, such as hiding or changing transparency. They simply store a group of items for later retrieval. There
is no intelligence behind this set - if the model changes at all, the same items will be selected (assuming
they are still available in the model) when recalling the selection set.
Search sets work in a similar way, except that they save search criteria instead of the results of a
selection, so that you can re-run the search at a later date as and when the model changes. See
Chapter 7, Finding for information on searching the model for items.
Selection and search sets can be named and contain comments. They can also be highlighted with icons
in the main navigation window, so that when you click on one, the selection set is restored to the active
set and all the items within it are re-selected.
6.3.1. Saving Selection and Search Sets

the specification are selected into the current selection.
6.3.3. Managing Selection Sets
As well as a tab on the selection tree, there is also a control bar dedicated to selection sets. To activate it,
click on
in the Workspace toolbar or go to View, Control Bars, Selection Sets:

This is the main management center for selection sets. All actions concerning selection sets are available
by right clicking on this control bar.
Right clicking on a blank space in the Selection Sets control bar opens a context menu with the options
to Save Current Selection or Save Current Search, as outlined in Section 6.3.1, “ Saving Selection and
Search Sets ”. This also gives access to the Add Folder and Sort options as detailed below.
Managing Selection Sets
1.
Right click on a selection set.
2.
Choose Add Folder to create a new folder above the selected item.
3.
Choose Save Current Selection to save the current selection as a selection set in the list. This set
will contain the currently selected items.
4.

11. Choose Rename to rename the selected selection set.
12. Choose Sort to sort the contents of the Selection Sets window alphabetically.
Using Folders to Manage Selection Sets
•
Folders in the Selection Sets control bar work in a similar way to how they do in Microsoft Windows.
They can be created by right clicking either on a blank space in the Selection Sets control, or on any
visible item in the list and selecting Add Folder from the context menu. If the item selected is a
folder, then the new folder will be created inside, otherwise it will be created in the root of the control
above the selected item.
Items in the list can also be dragged and dropped into and out of folders, including folders
themselves as well as their contents, simply by selecting the item, holding the left mouse button
down, moving over to where the item should be placed, and letting go of the left mouse button. In this
way it is possible to create a variety of nested folders containing any number of folders, selection and
search sets.
6.4. Selection Resolution
Selection resolution affects what geometry you select when selecting items in the main navigation window
using Select mode.
When you click on an item in Select mode, JetStream doesn't know what level of item to start selecting at
- do you mean the whole model, or the layer, or the instance, or group, or just the geometry? The
selection resolution tells JetStream what level in the selection tree to start selecting items at by default.
The options are:
•
Model
Selects the whole model.
•
Layer
Selects all items on a layer.
•
First Object
Selects the first item in the selection tree path that isn't a layer.
•
Last Unique
Selects the most specific item (furthest along the selection tree path) that is unique (not multiply
instanced).
•
Last Object
Selects the most specific item (furthest along the selection tree path) that is marked as a composite
object. If no composite object is found, the geometry is selected. This is the Default selection
129

The document is for study only,if tort to your rights,please inform us,we will delete
Selecting Items
resolution setting.
•
Geometry
Selects the last item in the selection tree path (most specific, but may be multiply instanced).
If you find you have selected the wrong level of item, you can interactively "cycle" through the selection
resolution, without having to go to the options dialog or the selection tree. You do this by holding down
the Shift key when selecting an item. This selects an item one level more specific each time you select
the item until the resolution gets to "geometry", at which point it will revert back to "model". The selection
resolution remains as set in options for the next selection.
As well as being able to set the default selection resolution in the Selection options tab in Global
Options, a quicker way is to right click on any item in the selection tree and choose the menu item Set
Selection Resolution to X, where X is one of the above selection resolutions.
6.5. Selection Options
Use the Selection options to configure how you select items in the JetStream scene. You can set the
level at which you select items (selection resolution), the distance from an item you have to be for it to be
selected (useful for lines and points) and also the color in which selected items are displayed.
Setting selection options
Go to Tools, Global Options, Selection.

Chapter 7. Finding
Finding is a quick and powerful way of selecting items into the current selection based on items'
properties. These "searches" can then be saved (see Section 6.3.1, “ Saving Selection and Search Sets
”) and re-run in later sessions.
You can also find text inside comments using the Find Comments functionality.
7.1. Properties
The Properties control bar shows all the properties of a selected item. Properties are categorized into
categories such as Item and Material and this control bar has a tab for each property category of the
selected item. Whenever a single item is selected, this dialog will be updated to show the properties of
that item.
Note
If more than one item is selected the Properties bar will only show the number of items selected
and won't show any property information.
The Properties control bar looks like this:
To activate it, click on the Properties button
on the Workspace toolbar, or go to View, Control
Bars, Properties.
Hyperlinks are also classed as a property category and so can be added and edited from this control bar
using the context menu. See Section 13.4, “ Hyperlinks ” for more details on hyperlinks.
JetStream will also convert many different CAD application object properties, such as those from
Architectural Desktop™ or MicroStation TriForma™.
133
www.cadfamily.com EMail:cadserv21@hotmail.com

Finding
Every property has a type associated with it, for example, an item's Name is a string, and so on. Some
properties are dependent on the current profile, so if you are more technically oriented and wish to see
more detailed property information, such as a file's transform check the profile level in Global Options,
Profile.
Properties can be brought in from an external database and shown inside database-specific tabs in the
Properties control bar. See Chapter 17, DataTools for more details on how to bring through object
properties using DataTools.
7.2. Finding Items
In JetStream, searching the model for items based on their properties is quick and simple using the Find
Items control bar. This bar is also a dockable bar accessed as usual through the View, Control Bars
menu, or from the Workspace control bar by pressing the Find Items button
. Alternatively, go to
Edit, Find Items.
The Find Items control bar looks like this:
Notice that the selection trees occupy the left half of this bar, allowing you to refine your searches further
within a specific hierarchy. See Section 6.1, “ Selection Trees ” for more information on the selection
trees. Simply click on the selection tree tab that best suits your current search.
Finding items based on properties
1.
If it's not already open, open the Find Items control bar as outlined above.
2.
Choose the selection tree tab that best suits your search. For example, if you know you are limiting
your find to within a specific selection set, then choose the Sets tab.
3.
Choose the items where you want to start the find from. For example, if you know you want to search
134
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
Finding
the whole model, then choose the file or files from the Standard tab that comprise the model. You
could also select several selection sets to limit your find to these items in the sets.
Note
You can right click on the selection tree and choose from Import Current Selection to quickly
select the items currently selected for the search, or conversely, Set As Current Selection to set
the current selection to that you have already selected in the find selection tree.
4.
The right hand side of the bar contains a list box with four columns, Category, Property, Condition,
and Value. This is where the find specification is set up. In this list box, you define a series of
conditions which are, by default, logically ANDed together as follows:
•
Each condition is started by clicking on the next available line under the Category column and
from the ensuing drop down, choosing which category the property you wish to search for is in.
Only the categories that are contained in the scene are available in the drop down.
•
After choosing the category, then choose the property you wish to test for in the Property drop
down which will then be available. Again, only the properties in the scene within the category
chosen will be available.
•
Then, from the following Condition drop down, choose the condition you wish to test for. This will
depend on the type of property you are searching for. For example, you can choose Contains to
search for a series of letters within a string. Wildcard means you can use wildcards in the Value
field to allow matching against any character or an arbitrary sequence of characters. The symbol
= means "exactly equals" and can be used for any type of property. The mathematical symbols, <,
>, <= and >= apply to number types and mean "less than", "greater than", "less than or equal to",
and "greater than or equal to" respectively. Also available are Defined and Undefined to mean
"anything" (in other words, it's there) and "nothing" (in other words, it's not there) respectively.
•
Finally, if you didn't choose either Defined or Undefined in the Condition column, you have to
define the Value you want to match in the find. You can either type in a value freely in the text
box, or choose a pre-defined value from the drop down which shows all values in the model
available within the category and property you defined earlier. If you chose Wildcard in the
Condition column you can type in a value with wildcards. To match one single unspecified
character use the symbol ?, for example, a Value field of "b??ck" will match "brick" and "block".
To match any number of unspecified characters, use the symbol *, for example, a Value field of
"b*k" will match "bench kiosk", "brick" and "block". Similarly, a Value field of "*b*k*" will match
"bench kiosk", "brick" and "block" and also "Coarse bricks" and "block 2".
5.
Continue to add conditions to the find specification. Each condition you add will by default be logically
ANDed with the others. See the example below for a better explanation of the logic.
6.
You can logically negate any condition by selecting the condition, then right clicking on the list box
and choosing Negate Condition. See the example below for a better explanation of the logic.
7.
Instead of the condition being logically ANDed, you can also logically OR a condition by selecting the
condition, then right clicking on the list box and choosing Or Condition. All conditions following this
condition are logically ANDed together and will be logically ORed with all conditions preceding this
condition (which are in turn logically ANDed together). A small "plus" will appear next to an ORed
condition. See the example below for a better explanation of the logic.
8.
To delete the selected condition, right click on the list box and choose Delete Condition from the
context menu. Alternatively, to delete all the conditions in the find specification, choose Delete All
Conditions from the context menu.
135

Finding
9.
The context menu that appears when right clicking on the list box also contains several Ignore
Category ... and Ignore Property ... options. See User Name and Internal Name for details on what
these mean.
10. Check the Match Case check box if you want the find to respect the upper and lower case letters in
strings. You can also define case sensitivity at the condition level by selecting the condition, right
clicking on the list box and choosing Ignore String Value Case from the context menu. This will then
ignore that condition's case when making comparisons. The Match Case check box should gray out,
showing that some conditions are case sensitive and other are not.
11. Check the Prune Below Result check box if you want to stop searching a branch of the selection
tree as soon as an item that matches the find specification is found.
12. From the Search drop down, select the type of search you want to perform.
•
Default searches all items selected in the selection tree, along with the paths below these itesm,
for matches with the search.
•
Below Selected Paths only searches below the items selected in the selection tree for matches
with the search.
•
Selected Paths Only only searches within the items selected in the selection tree for matches
with the search.
13. Click Find First for the first item in the selection tree to match any of the find specification, Find Next
to find the next item in the tree, and Find All to find all items matching the specification.
14. You can click on Abort Search at any time during a lengthy search to cancel the search.
15. Any items found will be selected in the selection tree and main navigation window.
Note
A small "star" will appear next to any condition that does not have the default settings, such as if
you negate the condition or check one of the Ignore... items on the context menu.
Find Item Example
Say you have set up four conditions in the search called C1, C2, C3 and C4. If you want to search for (C1
AND C2) OR (C3 AND NOT C4), then you would select condition 3 and choose Or Condition from the
context menu, and then select condition 4 and choose Negate Condition from the context menu. So all
conditions following the OR are ANDed together and this group of conditions is ORed with the first group
of conditions, which are also ANDed together. In other words, the precedence is NOT, then AND, then
OR.
7.3. Quick Find
As well as the more comprehensive and powerful Find Item feature (see Section 7.2, “ Finding Items ”),
JetStream also offers a simpler and quicker Quick Find. This simply searches for a string (case
insensitive) in all property names and values attached to items in the scene.

Quickly finding items from a string
1.
Go to Edit, Quick Find or press Ctrl-F. The Quick Find dialog will appear:
2.
Type in the string you want to search for in all items' properties. This search is not case sensitive.
3.
Click Find Next to find the next item in the selection tree containing this string or Cancel to return to
JetStream.
4.
If any items contain properties with the string being searched for, the next one in the selection tree
will be highlighted and the search stopped.
5.
To repeat the search, simply press F3 or go to Edit, Quick Find Next. If any more items contain
properties with the string, the next one in the selection tree will be highlighted and the search
stopped.
7.4. Finding Comments
As well as finding items by property, you can also search the comments attached to items, clash results
and selection sets using the Find Comments control bar. For more information on what comments are
and how to attach them to items, see Section 13.1, “ Commenting ”. Alternatively, go to Edit, Find
Comments.
As usual in JetStream, the Find Comments control bar is a dockable bar accessed through the View,
Control Bars menu, from the Review, Comments, Find Comments menu or from the Workspace
control bar by pressing the Find Comments button
.
The Find Comments control bar looks like this:

2.
Type in the text that you want to search for in the Text box.
Note
You should use the "*" wildcard (without the quotes) to match an arbitrary series of letters either
before or after the text you enter here. For example, if you want to find all comments containing
the word "redline", you should enter "*redline*" in the text box, otherwise you will only find
comments that contain only the "redline" word, which probably won't be many!
3.
If you want to restrict your search to comments made by a single author, then type in the name of
that author in the Author text box.
4.
If you know the ID of the comment you want to find, enter this in the ID text box.

which the comment must have been made.
8.
Clicking on the Source tab and check the relevant check boxes for Clash Detective, TimeLiner,
Selection Sets, Viewpoints or Redline Tags to restrict the search by the source that the comment
is attached to. The Clash Detective and TimeLiner options are only available if you have the relevant
plugin licenses.
Note
If the Text, Author, ID and Status fields are left empty, the search will return all comments within
the Date Modified and Source restrictions.
9.
Click Find to search for the comments.
10. If any comments are found, they will be listed in the box at the bottom of the control. Selecting a
comment will also select the source of the comment. For example, selecting a comment which
originated from a saved viewpoint will select that viewpoint.
If new comments are added, the results list will be cleared.

Chapter 8. Editing
As JetStream is a design review tool, editing is restricted to simple temporary "overrides" of items'
properties, so that they can always be reset to the state they were in when imported from the CAD file.
You can override an item's position by holding onto the item while navigating and then dropping it in a
new position, or move it by overriding it's transform. Also you can edit an items color, transparency, and
hyperlinks. In addition, you can hide and reveal items and make them required and unrequired to control
their drop out during navigation. Finally, you can also edit a file's transform, or in other words, its origin
location, scale, rotation and so on, so that it fits within the scene when appending multiple models from
potentially different sources and CAD applications.
Most editing is done from the Edit menu, which includes the following items:
•
Undo
•
Redo
•
Select
•
Quick Find
•
Quick Find Next
•
Find Items
•
Find Comments
•
Hide Item
•
Item Required
•
Hide Unselected Items
•
Override Item
•
Reset Item
•

•
File Units and Transform
The two main editing functionalities not available from the Edit menu are hyperlinks and holding items.
8.1. Holding and releasing objects
When navigating around a model in JetStream it is possible to "pick up" or hold selected items and move
around with them in the model. For example you may be viewing a plan for a factory and would like to see
different configurations of machine layouts.

material overrides can be optionally saved into viewpoints (see Section 10.6, “ Viewpoints Options ”).
8.6.1. Overriding Color
This option allows a user-defined color to be added to an item in the scene. The old color is saved in case
it needs to be reset later.

4.
Click OK to apply the transform, or Cancel to return to JetStream without applying it
Also see Section 13.3.2, “ Transforming Objects ” for more information on interactively transforming
objects.
8.6.4. Overriding Hyperlinks
As well as hyperlinks being converted from the native CAD files you open in Roamer, you can also
"override" an item's hyperlinks by attaching multiple additional hyperlinks to it. Because hyperlinks are
treated as a property by JetStream, they can be searched on with the Find Items tool and displayed in
the Properties bar. They are also saved into JetStream files so that as the model changes, the links
remain for you and others to view.
See Section 13.4, “ Hyperlinks ” for more information on overriding hyperlinks.
8.7. Resetting Overriden Properties
Once an override has been applied to an item, you simply reset that override to return it to the value that

8.10. Setting a File's Units and Transform
You may need to use this feature when working with Clash Detective and/or Presenter, where it's
important to have the model in the correct units and scale, to ensure clash results are accurate and
materials are applied correctly. You may also find this useful if you append several models from different
sources into the same scene and the scale, rotation and origin of some models need amending to match
the other models.
The first thing to try, however, before attempting to manually adjust the file's transform, is to check that
the units are ok. See Section 14.10, “ Units ” for a discussion of units and how to adjust them.

Chapter 9. Display Modes
The Rendering Styles toolbar controls the appearance of the model in the main navigation window. From
this you can control the lighting effect, the rendering type and enable or disable the different types of
primitives drawn. Linked with the display options (see Section 9.5, “ Display Options ” later in this chapter)
and file options (see Section 16.1, “ File Options ”, this enables you to fully control the appearance of the
JetStream main navigation window.
9.1. Rendering Styles
The rendering process interactively draws the scene's items in the main navigation window. You have a
choice of one of four interactive lighting modes (full lights, scene lights, head light, or no lights), four
rendering modes (full render, shaded render, wireframe or hidden line) and you can individually turn each
of the four primitive types (surfaces, lines, points and snap points) on and off.
The Rendering Style toolbar looks like this:
If it is not already displayed, you can display it from the View, Control Bars, Rendering Style menu.
9.1.1. Lighting
Lights come through from various CAD file formats as scene lights. The intensity of the head light and
scene lights can be set using the File Options under the Tools menu (see Section 16.1, “ File Options ”
for details on this).
The spheres below demonstrate the effect the lighting styles have on them. In order from the left, these
are full lights, scene lights, head light and no lights.
9.1.1.1. No Lights
This option turns off lighting. The models are shaded with flat rendering.
To turn off all lights

9.1.2. Render Modes
The four render modes affect how the items are rendered in the main navigation window.
The spheres below demonstrate the effect that the render modes have on their appearance. In order from
the left, these are full render, shaded, wireframe and hidden line.
9.1.2.1. Full Render
This option renders the model with smooth shading including any Presenter materials that have been
applied using JetStream Presenter or have been brought through from the native CAD file (although
JetStream does not convert all native CAD file's textures - see Chapter 3, Converting Files for more
details).
To select full render
•

or
•
Click Hidden Line
on the Rendering Style toolbar.
9.1.3. Display Primitives
The second part of the rendering style toolbar allows you enable and disable the drawing of surfaces,
lines, points and snap points. Points are "real" points in the model, whereas snap points mark locations
on other primitives, for example the center of a circle, and are useful for snapping to when measuring.

Setting the background color
1.
Go to Tools, Background Color
2.
Select the color from the Windows™ color palette.
3.
Click OK to set the background color or Cancel to exit the dialog without setting it.
9.2. Culling Options
There are three methods of culling objects in JetStream: backface, by area, and by near or far plane. All
of these options are configurable using the Culling options tab.
Backface culling only draws the front face of every polygon in JetStream, which is clearly faster.
Sometimes, however, the conversion process mixes up the front and back face of polygons and so you
have to tell JetStream to draw both sides in order to not see right through some objects.
Area culling options allow you to set the size of objects within a model that will not be displayed. For
example, if you were to set the value to 100 pixels any object within the model that would be drawn less
than 10x10 pixels in size will not be displayed.
Culling options by near and far plane allows some degree of control over the resolution of the axis
perpendicular to the screen. JetStream uses the near and far clip plane to maximize the resolution of the
model on screen. The near and far clip plane boxes dictate constraints for the near and far culling planes.
Setting culling options
1.
Go to Tools, File Options, Culling
The Culling dialog is displayed

2.
Check the Area, Enable check box to enable the definition of the screen area (in pixels) below which
objects are culled and type in the number of pixels in the text box.
3.
In the Near Clip Plane area, check the Automatically generated check box to tell JetStream to
constrain the near plane to give the best view of the model it possibly can. Alternatively, uncheck this
box to manually constrain the near clip plane. JetStream will put the near clip plane no further than
the value you type into the Furthest distance text box.
4.
Similarly, in the Far Clip Plane area, check the Automatically generated check box to tell
JetStream to constrain the far plane to give the best view of the model it possibly can. Alternatively,
uncheck this box to manually constrain the far clip plane. JetStream will put the far clip plane no
closer than the value you type into the Closest distance text box.
5.
From the Backface drop-down, select On to enable backface culling of all objects. Select Solid to
cull the backface of solid objects only. This is the default option and that which you are most likely to
require. If you find that parts of items are missing in the JetStream scene, you might want to disable
this option, by selecting Off.
6.

JetStream has a concept of orientation and provides a heads up directional display. For this to work
effectively, it is essential that the current model is orientated correctly.
1.
Go to Tools, File Options, Orientation.
The Orientation dialog is displayed:
The defaults take the positive Z-axis as Up and the positive Y-axis as North.

9.4. Speed Options
165
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
Display Modes
The basis of JetStream Roamer is its ability to walk through any size model in real time. JetStream
guarantees a user-defined frame rate using a unique algorithm which automatically calculates which
items to render first during navigation, based on the size of items and distance from the viewpoint. Items
which JetStream does not have time to render are therefore sacrificed or "dropped out" in the name of
interactivity. These items are, of course, rendered when navigation ceases. The amount of drop-out
depends on several factors including: hardware (in particular graphics card and driver performance - for a
list of recommended graphics cards, visit www.navisworks.com [http://www.navisworks.com]), as well as
the size of the JetStream navigation window and the size of the model. If you wish to reduce drop-out
during navigation, you have the option to reduce frame rate and therefore trade it off against drop-out.
You can set the frame rate anywhere between 1 and 60 frames per second.
Setting the frame rate
1.
Go to Tools, File Options, Speed.
The Speed dialog is displayed:
2.
Select the number of frames per second to be applied to the rendered display of the model.

Check the Occlusion Culling check box to have JetStream only draw visible objects, i.e. ignores
objects that are behind other objects. This option will improve the display performance when much of
the model is not visible. For example, when you're walking down the corridor of a building. Occlusion
culling can only be utilized on a machine with an OpenGL 1.5 compliant graphics card.
4.
Check the Interactive Transparency check box to allow the rendering of transparent items during
interactive navigation. This may have an effect on performance - especially if your video card does
not support hardware accelerated OpenGL - and so by default transparent items are only drawn
when interaction has ceased.
5.
Check the Guarantee Frame Rate check box to enable the JetStream engine to maintain the user
defined frame rate set in Tools, File Options, Speed (see Section 9.4, “ Speed Options ”). By
default the target rate is maintained while moving. When movement stops the complete model is
rendered. If guarantee frame rate is disabled the complete model is always rendered during
navigation, no matter how long it takes.
6.
Check the Fill In Detail check box if you want JetStream to fill in any discarded detail when
navigation has ceased.
7.
Check the Batch Fill check box if you want JetStream to fill in detail in chunks rather than gradually.
By default this is disabled as gradual rendering is generally better but some video cards may work
better with batch fill enabled.
8.

Alternatively, uncheck this option and manually enter the limit.
3.
On Load. The Collapse on Convert list box can be set to alter layers shown in the Selection Set
window on loading native CAD model files. Each type collapses the Selection Set tree up to the
specified level. So None does not collapse the tree, Composite Objects collapses the tree up to the
level of composite objects, etc. This enables performance to be prioritized over structure/properties
and has the added benefit of improving streaming by cutting down the logical structure.
It should be noted that whilst JetStream will try to collape items to the fewest number possible, it may
be necessary to prevent collapsing in some cases to preserve model fidelity. For example if an item
has properties or materials unique to itself, then collapsing would endanger this information, and
therefore it will not be collapsed.
The Close NWC/NWD files on load check box, if checked, turns off any streaming on loaded NWC
and NWD files, loading them into memory in their entirety, and then closing them. This allows other
programs to write to these files whilst they are in use.
4.
Merge Duplicates. These options improve performance by multiply instancing matching items.
Rather than storing every item in memory, if any items are the same, JetStream can store one
instance of them and 'copy' that instance into other positions. This is of particular benefit on larger
models, where there are significant numbers of these duplicate geometries.
The options available determine when JetStream should perform this merging process:
5.
•
On Convert. Merge duplicates when converting a CAD file.
•
On Append. Merge duplicates when a new file is appended to the current scene.
•
On Load. Merge duplicates when loading a file into JetStream.
•
On Save NWF. Merge duplicates when saving the current scene out to .nwf.
Temporary File Location. Check the Auto check box for JetStream to automatically select your
user Temp directory. Alternatively, if you prefer to select another location, unselect this option and
enter the path accordingly.
9.7. Presenter Options
This dialog is used to control the appearance of Presenter materials in the main navigation window during

style is on. Unchecking this will ease the load on less capable graphics cards and give less drop out
in heavily textured scenes.
5.
Uncheck the Interactive Lighting check box if you want to turn off Presenter lights during navigation.
The lights reappear automatically when navigation ceases, as long as the Full Lights lighting style is

heavily lit scenes.
6.
Use the Max Texture Size drop down to set the maximum size that any texture can be (in pixels, e.g.
128 is 128 pixels x 128 pixels). The higher the value, the more MB in memory will be taken and thus
performance could be affected on less capable graphics cards.
7.
Use the Max Image Texture Size drop down to set the maximum size that any texture image can be
(in pixels, e.g. 256 is 256 pixels x 256 pixels). The higher the value, the more MB in memory will be
taken and thus performance could be affected on less capable graphics cards.
8.
Similarly, use the Max Background Texture drop down to set the maximum size that the
background texture can be (in pixels, e.g. 256 is 256 pixels x 256 pixels). The higher the value, the
more MB in memory will be taken and thus performance could be affected on less capable graphics
cards.
9.
Check the Blend Transparent Textures check box if you want better quality but slower rendering of
transparent items in the main navigation window. With this option off, items with transparency of
more than 50% are treated as completely transparent and not rendered at all.
10. Check the Use Texture Anti-Aliasing check box if you want procedural materials (such as some
bricks and tiles - you can tell a procedural material in Presenter because it has a ball style preview
icon) to be rendered using anti-aliasing. With this option on, it will take longer to open files containing
procedural textures, but the quality will be better.

Chapter 10. Viewpoints
Viewpoints are an important feature of JetStream. They not only allow you to save and return to views of
the model which are of importance, but they can also be used for design review audit trails and for setting
up animations of the model.
10.1. Saving Viewpoints
Viewpoints contain more than just the camera information - each viewpoint can also contain redlines and
comments. In fact, you can use viewpoints as a design review audit trail. They can be used as hyperlinks
in the main navigation window to click on and zoom to the viewpoint, which will also bring up the redline
and comments associated with it. The viewpoints, redlines and comments are all saved into an .nwf file
from JetStream Roamer, so even if the native CAD files are changing, the saved viewpoints remain the
same over the top, so you can see how the design has evolved. See Chapter 13, Reviewing for more
information on hyperlinks, comments and redlines and Section 3.1.1, “ NWF Files ” for more information
on the .nwf file format.
Viewpoints also retain the section planes active at the time of viewpoint creation, which can be useful in
animating sliding sections. See Section 11.1, “ Sectioning a model ” for more information on sections.
Viewpoints can optionally retain saved attributes too, so that on returning to a viewpoint, overridden
colors, transparencies and hidden items are reinstated. This can be used to great effect to create
animations where items appear and disappear from the scene in time. See Section 10.6, “ Viewpoints
Options ” for more information on options and Section 12.1, “ Creating Animations ” for more information
on animations.
To save a viewpoint
•
Go to Viewpoint, Saved Viewpoints, Save Viewpoint.
or
•
Right click on the Viewpoints control bar and choose Save Viewpoint.
New viewpoints are named "ViewX" where 'X' is the next available number added to the list. This new
viewpoint will take all the attributes of the current viewpoint in the main navigation window.
10.2. Recalling Viewpoints
To return to a viewpoint
•
Go to Viewpoint, Saved Viewpoints and choose the saved viewpoint from the list.
or
•
In the Viewpoints control bar, simply click on the viewpoint from the list.

Viewpoints
On recalling viewpoints the navigation mode that was active when the viewpoint was created will
be re-selected. Any redlines and comments associated with the viewpoint will also be reinstated.
10.3. The Viewpoints Control Bar
Viewpoints allow you to keep a record of all the different views of a model so that you can jump to preset
viewpoints without having to navigate each time to reach an item. Animations are also saved with the
viewpoints, as they are simply a list of viewpoints treated as key frames of the animation. In fact,
animations can be made by simply dragging preset viewpoints onto an empty animation. See
Section 12.1, “ Creating Animations ” for more information on animations. You can also organize your
animations and viewpoints using folders.
The Viewpoints control bar is shown above. To open it,
•
Go to View, Control Bars, Viewpoints
or
•
Click Viewpoints
on the Workspace toolbar.
Icons are used to represent different elements:

represents an animation clip.
represents a cut inserted into an animation clip.
You can select more than one viewpoint by either holding down the Control key and left clicking, or by
left clicking on the first item, and then clicking on the last item while holding down the Shift key. You can
drag viewpoints around the viewpoints control bar, and reorganize into folders or animations.
There are no buttons on this control bar, and commands are actioned through context menus. Through
these menus, you can save and update viewpoints, create and manage animations and create folders to
organize these viewpoints and animations. You can also drag and drop viewpoints or animations onto
animations or folders, and holding down the Control key during this operation will copy the element being
dragged. This allows fairly complex hierarchies of animations and folders to be easily composed.
Viewpoints, folders and animations can all be renamed by slow clicking (clicking and pausing without
moving the mouse) on the element, or clicking on it and hitting F2. Right clicking on an element in the
Viewpoints control bar gives you a different context menu, depending on the element, or if you've right

10.6. Viewpoints Options
Two view attributes can be saved with a viewpoint:
•
Hide/Required - whether items are hidden or required.
•
Override Materials - the color and transparency of items.
You can set a viewpoint to save either attribute by editing the viewpoint. To update changes to overridden
material or hide/required, use Update in the viewpoints context menu. Be careful, though, as this also
updates the point of view as well, which may disrupt any redline information stored with the viewpoint.
By default these attributes are not stored with new saved viewpoints. If you do wish them to be saved by
default, then this can set in the Viewpoints Options.

Chapter 11. Sectioning
Sectioning allows you to make up to 6 sectional cuts in any plane while still being able to navigate around
the scene, enabling you to see inside models without hiding any item. Section planes are stored inside
viewpoints and so can also be used within animations to show a dynamically sectioned model. See
Section 10.3, “ The Viewpoints Control Bar ” for more information on viewpoints and Section 12.1, “
Creating Animations ” for more information on animations.
Slices can also be created using two opposing section planes and linking them. In this way you can move
a slice through the scene in real time and can again link this to animations and viewpoints.
11.1. Sectioning a model
There are up to 6 section planes enabled at one time, but there is only one that is active. The section
plane that is active is numbered in the drop down box. However, you can link section planes together to
form slices.
The Sectioning toolbar is shown above. To open it,
•
Go to View, Control Bars, Sectioning
or
•
Click Sectioning
on the Workspace toolbar.
Manipulating the active section plane
1.
Choose the plane that you wish to manipulate using the numbered drop down. In this drop down,
there will always be one more than the number of enabled section planes in the scene, up to a
maximum of 6.
2.
Set the Step Size by clicking on the step size button.
This brings up a dialog box allowing a
Step Size to be enabled and set to a user-definable size. This size is then used when moving the
section planes. If the Step Size is disabled, the section planes will move at percentage intervals.
3.
Switch this plane on or off by clicking the section toggle button.
4.
Once switched on, choose one of the 7 planes that this section plane will cut. You have the choice of
•
Align Viewpoint
This will align the plane parallel with the current viewpoint.

Note
Each plane for each section remembers its position, so the slider will move when you choose
another plane.
5.
Move the slider to interactively position the section plane to the required location. The number in the
edit box shows the position of the section plane from the origin and will be updated when moving the
section plane. You can also type in the location of the origin in this edit box for exact positioning of
the plane.
Note
You can also use the cursor keys and mouse wheel for simple sliding of the section plane through
the model.
6.
Clicking on the Set Range button
helps you to set a finer resolution for sectioning large models.
What this button does is limit the range of the section planes to the bounding box limits of the
currently selected items. For more information on selecting items, see Chapter 6, Selecting Items .
Clicking this button with nothing selected reset the section range to the limits of the whole model,
which is the default.
7.
If you have more than one section plane enabled, you can delete this active plane using the delete
button
. The next enabled plane will then become the active plane.

Sectioning
11.2. Linking Sections
You can add up to 6 section planes to the scene at once using the above procedure. Once more than one
plane is enabled, you can then link them together. This becomes particularly effective when opposing
planes such as top and bottom are linked. Sliding the plane through the model then gives a "slice". The
following is an example of creating a horizontal slice using the top and bottom section planes:
Slicing the model
1.
Set up the bottom plane as described in Section 11.1, “ Sectioning a model ”.
2.
Choose 2 in the drop down.
3.
Enable this with the section toggle and select the Align Top plane.
Note
The model may disappear completely at this stage. If so, just slide the slider until it becomes
apparent where the plane is.
4.
Keep switching between planes 1 and 2 using the drop down and configure the planes' position to
how far you want them separated in the slice.
5.
When happy with their separation, select section plane 2 and click on the Link button
This links
planes 2 and 1 together to form the slice.
6.
Use the slider bar to move the horizontal slice through the model.
7.
If you want, you can save this slice configuration into a viewpoint. See Section 10.1, “ Saving
Viewpoints ” for more information on how to do this.
Thinking about linked sections and slices can be confusing. Just remember that when linking sections
together, the section plane direction currently in operation effectively moves the whole "box" around the
scene, keeping the other section planes relative to it.

Chapter 12. Animating
JetStream allows the recording, playing and editing of both your movement through the model and views
of the model. An animation toolbar is provided for the recording and playback of animations and this is
linked to the Viewpoints control bar, which can be used to make animations from scratch by building up
an animation frame by frame (viewpoint by viewpoint). The Viewpoints control bar can then be used to
save, edit, rearrange and manage your animations in folders, including inserting cuts and dragging and
dropping animations onto other animations to build up a more complex animation from simpler ones. At
any time during an animation playback, you can stop the animation and have a real time look around
before restarting it. Once you are happy with the animation, you can export it as an .avi file.
It is worth remembering that you can hide items in viewpoints, override colors and transparencies and set
multiple section planes and these will all be respected by an animation. This way you can very simply
create powerful animations.
12.1. Creating Animations
There are two ways to create animations in JetStream. You can either simply record your real time walk
through, or you can assemble specific viewpoints for JetStream to interpolate into an animation later for a
more controlled animation.
All animation is controlled through the Tools, Animation menu, the Viewpoints control bar and the
Animation toolbar, which is shown below.
Creating an animation in real time
1.
Click on the Record button
on the Animation toolbar.
2.
Navigate around in the main navigation window while JetStream records your movement. You can
even move the section plane(s) through the model during your navigation and this will be recorded
into the animation too.
3.
At any point during the navigation, you can click on the Pause button
. This will pause the
recording while you maneuver into a new position. Click on the Pause button again to continue
recording the animation. The resulting animation will contain a cut for the duration of the pause.
4.
When finished, click on the Stop button
.
5.
A new animation called "AnimationX", where 'X' is the latest available number, will be added to the
Viewpoints control bar. The name will be editable at this point if you want to name it yourself. This
animation will also become the current active animation in the Animation toolbar's drop down.
While the above method is useful for creating quick animations on the fly, sometimes you need more
control over the animation camera. To do this in JetStream, you need to set up several viewpoints and
188

The document is for study only,if tort to your rights,please inform us,we will delete
Animating
add them to an empty animation. When playing back the animation, JetStream will then interpolate
between these viewpoints.
Creating an animation frame by frame
1.
Right click on the Viewpoints control bar and select Add Empty Animation from the context menu.
2.
A new animation called "AnimationX", where 'X' is the latest available number, will be added to the
Viewpoints control bar. The name will be editable at this point if you want to name it yourself. There
will be no plus sign next to the animation, showing that the animation is indeed empty.
3.
Create the viewpoints where you want the camera to move through during the animation and save
these into the Viewpoints control bar. These will become the frames for the animation. The more
frames you have, the smoother and more predictable the animation will be. See Section 10.1, “
Saving Viewpoints ” for more information on creating viewpoints.
4.
When you have all the viewpoints, simply drag them onto the empty animation you just created. You
can drag them on one by one, or select multiple viewpoints using the Control and Shift keys and
drag several on at once. If you drop them onto the animation icon itself, then the viewpoints will
become frames at the end of the animation, but you can drop the viewpoints anywhere on the
expanded animation to put them where you wish.
5.
At this point, you can use the slider bar on the Animation toolbar to move backward and forward
through the animation to see how it looks.
6.
You can edit any of the viewpoints inside the animation (see Section 10.5, “ Editing Viewpoints ” for
details on this), or you can add more viewpoints, delete them, move them around, add cuts and edit
the animation itself (see Section 12.2, “ Editing Animations ”) until you are happy with the animation.
7.
Once you have several animations, you can drag and drop them onto a master animation to
compose more complex combinations of animations, just like dragging and dropping viewpoints onto
an animation as a frame.
12.2. Editing Animations
Once an animation is recorded, you can edit it to set the duration, the type of smoothing and whether it
loops or not.
Editing an animation
1.
Right click on the animation you want to edit in the Viewpoints control bar.
The Edit Animation dialog is displayed
189
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
Animating
2.
Type in the duration in seconds in the Duration edit box.
3.
If you want the animation to play back continuously, check the Loop Playback check box.
4.
From the Smoothing drop down, select the type of smoothing you want the animation to use. None
means that the camera will move from one frame to the next without any attempt at smoothing out
the corners. The speed of movement between frames of an animation is dictated by the angular and
linear speeds of the individual frames and so choosing Synchronise angular/linear speeds will
smooth the differences between the speeds of each frame in the animation, resulting in a less jerky
animation.
5.
Click OK to set these options, or Cancel to return to JetStream leaving the animation as it was.
There is also nothing to stop you copying animations (hold down the Control key when dragging an
animation in the Viewpoints control bar), dragging frames off the animation into a blank space on the
Viewpoints control bar to remove them from the animation, editing individual frames attributes, inserting
cuts or dragging other viewpoints or animations onto the existing one, to continue developing your
animations.
12.3. Animation Cuts
Cuts in an animation are simply points where the camera pauses for a while. They are inserted
automatically when you click on Pause during the interactive recording of an animation, or you can insert
them manually into an existing animation.
Inserting pasues into an animation
1.
Right click on the frame below where you want to insert the cut.
2.
Choose Add Cut from the context menu.
3.
Type in the name of the cut, or hit Enter to accept the default name, which will be "CutX", where 'X' is
the next available number.
4.
This default duration of a cut is 1 second. To alter the duration of this pause, right click on the cut and
choose Edit.
The Edit Animation Cut dialog is displayed

5.
Type in the duration of the pause in seconds.
6.
Click OK to set the duration or Cancel to return o JetStream without setting it.
12.4. Playing Back Animations
You can choose any one of the animations saved in the Viewpoints control bar to play back in real time
in the main navigation window. Playing back an animation in real time means that the NavisWorks engine
is still attempting to maintain the guaranteed frame rate and so some drop-out may still occur, just as in
real time navigation. However, you can export the animation to an .avi file for playback with Windows
Media Player™ and this will render each frame without any drop out. Of course, you don't have the option
of pausing the playback half way through to look around the mode using this method! See Section 2.15.3,
“ Exporting an animation ” for details on how to export an animation to .avi.
Playing back an animation
1.
Select the animation you wish to play back from either the Viewpoints control bar, or from the drop
down on the Animation toolbar.
2.
You can use the slider to quickly move forwards and backwards through the animation. Full left is at
the beginning and full right is at the end. The text box next to the slider shows the point in time (in
seconds) through the animation that the camera is. You can type a number into this box to set the
camera at a certain point in the animation and play back from that point.
3.
Notice how the frame in the animation in the Viewpoints control bar is highlighted when the
animation is playing. You can click on any frame to set the camera to that point in time in the
animation and continue playing back from there.
4.
Use the buttons on the Animation toolbar to step and play forwards and backwards through the
animation:
•
Rewind
•
Step Back
•
Reverse Play

Chapter 13. Reviewing
JetStream offers several design review tools to help you review a model and communicate those reviews
to others. Any reviewing you save in the model can also be saved into an .nwf file so that you can reload
the reviews into a later session when the model has changed, or to pass onto colleagues to communicate
design intent or problems.
The reviewing tools available in JetStream are:
•
Commenting
•
Redlining (including tagging)
•
Measuring
•
Hyperlinks
•
Collaboration
•
SwitchBack
13.1. Commenting
Multiple comments can be attached to any item in the Viewpoints control bar (see Section 10.3, “ The
Viewpoints Control Bar ”), or to any item in the Selection Sets control bar (see Section 6.3, “ Selection
and Search Sets ”), or to Clash Detective results, or to TimeLiner tasks.
The Comments control bar allows you to view all comments attached to one of these sources. Click on
in the Workspace toolbar or go to View, Control Bars, Comments to toggle the Comments
control bar on and off.
When the source of the comments is recalled, such as a viewpoint, all comments attached to it appear in
the Comments control bar, showing the time and date, author, ID and status of each comment. The icon
on the far left represents the source type:
Selection set.

TimeLiner.
With many comments attached to many sources in a model, you may want to find a particular comment
without having to manually search each possible source. See Section 7.4, “ Finding Comments ” for
details on how to achieve this.
Note
The first line of a comment is what is displayed in the top half of the Comments control bar and
can be treated like its "subject". To get multiple lines in a comment, hold down Control and press
Enter. This will give you a carriage return in the text box, rather than simulating a press of the OK
button.
Any new comments will automatically be given a unique ID, along with the date and author of the
comment and a status can be set. All of these are searchable criteria.
Once a comment is added, it can be edited or deleted.
Adding, Editing and Deleting Comments
You can add, edit and delete as many comments as you wish to a source, either from the Comments
control bar, or from the source itself.
Adding a comment from the Comments control bar

Renumbering tag and comment IDs
When adding a new tag or comment to a JetStream scene, it will automatically be assigned a unique ID. If
however, you are Appending or Merging multiple JetStream files together, then there is the possibility for
the same ID to be used more than once. In this situation, you may choose to renumber all of the IDs,
making them unique to the scene, once again.
1.
To renumber tag IDs:
•
Go to Review, Renumber Tag IDs.
Note
There may be a situation where two sessions are merged that contain identically numbered Tags
and corresponding Tag Views. In this situation, Renumber Tag IDs will also attempt, wherever
possible, to rename the associated Tag Views in line with the new tag numbers.
2.
To renumber comment IDs:

13.2. Redlining
Redlining allows you to add annotation directly over a viewpoint. It is mutually exclusive to the navigation
modes so that when you are redlining, you cannot navigate and vice versa.
The redline tools, which can all be accessed from the Redline Tools control bar or from the Review,
Redline menu, are:
Text
Tag
Freehand
Line
Line String
Ellipse
Cloud

13.2.1. Adding Redlines
The Redline Tools control bar is a dockable bar like all others in JetStream. It can be accessed by
clicking
on the Workspace control bar or by going to Tools, Redline.

Reviewing
Note
Redlines can only be added to a saved viewpoint or to a clash result which has a saved
viewpoint. If a viewpoint is not selected, a warning is given if a redline tool is selected.
Redline Tags are the exception to this rule. If a viewpoint is not already saved, then adding a tag
will automatically save a viewpoint. See Section 13.2.2, “ Adding Redline Tags ” for more
information.
Adding a redline to a saved viewpoint
1.
Go to a saved viewpoint, or a Clash Detective result with the Save Viewpoint check box checked.
2.
Ensure the Redline Tools control bar is displayed as outlined above.
3.
Type the thickness of the redlines into the Thickness edit box. The thickness applies to the redlines
you are about to draw and will not change any existing redline thicknesses.
Note
Thickness does not effect redline text. This is a default size and weight.
4.
To change the color of the redline (they don't have to be red!), click on the Color button to open the
standard Windows™ color chooser. This color applies to the redlines you are about to draw and will
not change any existing redline colors.

main navigation window with the left mouse button to outline the ellipse.
11. Choose the Cloud
redline tool to draw clouds over the viewpoint. With the left mouse button,
click points in the main navigation window in a clockwise direction to draw the arcs of the cloud (if
you go counter-clockwise, the arcs will be inverted!). Right click with the mouse button to
automatically close the cloud.
12. Choose the Erase
redline tool to erase all redlines from the viewpoint.
Note
You can also access all the redline tools from the Review, Redline menu.
13.2.2. Adding Redline Tags
Redline Tags combine the features of redlining, viewpoints and comments into a single, easy to use
review tool. This allows you to tag anything you want to identify in the model scene. A viewpoint will be
created and you can add a comment and status to the tag. For example, during a review session, you
may observe an item in the scene that is incorrectly sized or positioned. You can then tag this item,
identifying the problem. This tag information can be saved into a JetStream review file (*.nwf) and
distibuted to the design team. The design team may then search the file, say for any tags of status 'new'.
Once any necessary modifications are made to the drawing files, these can be reloaded into the *.nwf file
and the tag status changed accordingly. You can review this latest version of the review file, ensure all
tags have been resolved and finally 'approve' them.

Click OK to save the tag, or Cancel to return to JetStream without saving it.
13.2.3. Finding Redline Tags
During a review session you may create tens, or hundreds of tags which are communicated and referred
to amongst the review team. It may therefore be necessary to locate tags by ID, status or author.
As redline tags utilize the Comments dialog, this allows you to use the Find Comments dialog to search
for tags with specific text or ID, of a particular status, or by author or date created. See Section 7.4, “
Finding Comments ” for more information on this search method.
JetStream also has additional review features specifically for finding tags.

13.2.4. Editing Redline Tags
The comments and status assigned to a tag can be edited. As redline tags utilize the Comments dialog,
editing tags is the same as editing a comment. See Editing a Comment for more information.
If different users have been reviewing and redline tagging the same model file, each saving their own
.nwf, it is likely that some of their tag ID's will be the same. Using the Merge command to merge the
different .nwf files together, only one copy of the geometry would be loaded and any tag viewpoints of the
same name would be suffixed with the .nwf filename in brackets. All tag ID's however would be retained.
In this situation, it is possible to renumber all of the ID's to make them unique. Again, as redline tags
utilize the Comments dialog, renumbering tag ID's is the same as renumbering comment ID's. See
Renumbering Tag and Comment IDs for more information.
13.3. Measuring
Measuring allows you to measure between points on items in the model. All measurements are made in
the scene's units. For information on how to set the units, see Section 14.10, “ Units Options ”.
Like redlining and selecting, it is mutually exclusive to the navigation modes so that when you are
measuring, you cannot navigate and vice versa.
The measure tools, which can all be accessed from the Measure Tools control bar or from the Review,
Measure menu, are:
Point to point

Angle
Area
Transform objects
13.3.1. Measuring Tools
The Measure Tools control bar is a dockable bar like all others in JetStream. It can be accessed by
clicking
on the Workspace control bar or by going to Tools, Measure.
Use the buttons at the top to select the type of measurement you want to do.
For all measurements, the x-, y-, and z- coordinates of the Start point and End point are displayed in the
text boxes underneath the buttons, as are the Difference and the absolute Distance. If an accumulative
measure is being used, such as Point Line or Accumulate, Distance will show the accumulated
distance for all points registered in the measurement. All these measurements are shown in scene units.
All points will be represented in the main navigation window with a small cross, and all lines being

measured, by a simple line between points. You can use the Measure Options to choose how these are
displayed.
Note
It goes without saying that you must click on a point on an item to register a point - clicking on the
background will not register anything, but it is worth noting that you can snap to certain points on
items - see Section 13.3.1, “ Snapping ” for more details.
You can reset a measure command at any time by right clicking instead of left clicking in the main
navigation window. This will start the measure command again with no points registered, just as if
you had chosen a new measurement type.
Measuring between points on items
1.
Ensure the Measure Tools control bar is displayed as outlined above.
2.
To simply measure the distance between two points, choose the Point to Point measurement type
on the Measure Tools control bar and click on the start point and then the end point with the
left mouse button.
3.
To lock the start point and then click on multiple different end points, choose the Point to Multiple
Points measurement type
on the Measure Tools control bar and click on the start point. Every
other click after the start point will then register a new end point, but you can right click to reselect a
start point.
4.
To measure the distance along a path or route, choose the Point Line measurement type
on
the Measure Tools control bar and simply click on a series of points along the path. The Distance
will display the total distance along the path from the start point. Right clicking will enable you to
select a new start point.
5.
To calculate the sum total of several point-to-point measurements, choose the Accumulate
measurement type
on the Measure Tools control bar and click on start and end points
alternately. The Distance will show the sum of all point-to-point measurements since the first start
point. Right clicking will enable you to reset the distance to zero and restart the calculation.
6.
To calculate an angle between two lines, choose the Measure Angle measurement type
on the
Measure Tools control bar and click on a point on the first line, followed by the intersection of the
two lines, followed by a point on the second line. The Angle will show the angle between the three
points. Right clicking will enable you to select a new first point.
7.
To calculate an area on a plane, choose the Measure Area measurement type
on the Measure
Tools control bar and simply click on a series of points to describe the perimeter of the area you wish
to calculate. The Area will show the area of the perimeter described since the first point, as projected
onto the plane of the viewpoint. This means that all your points should lie on the same plane for your
area calculation to be perfectly accurate. Right clicking will enable you to select a new first point.

Snapping
The measure options dialog allows you to set the cursor to snap to the nearest vertex, edge or line end.
Points and snap points are automatically snapped to. Different cursors feed back what is being snapped
to:
No snap, but a point on a surface is found.
A vertex, point, snap point or line end is found to snap to.
An edge is found to snap to.
Note
The geometry in JetStream is tessellated with triangles, and therefore the cursor will snap to
edges that may appear to be in the middle of a face. Viewing the model in hidden line mode will
make it clear which vertex or edge the cursor is snapping to.
13.3.2. Transforming Objects
The transform objects tool allows you to reposition or rotate an object, defined by points selected with the
measure tools.
Repositioning objects
1.
Select the object to be repositioned (see Chapter 6, Selecting Items for more information on how to
do this).
2.
Choose one of the measure tools, from Point to Point, Point Line or Accumulate.
3.
Select a base point on the selected object. This is the reference point on the object from which the
repositioning will be calculated.
4.
Select another point in the scene (or multiple points, depending on which measure tool you selected).
This is the point (or points) which the base point will be repositioned to.
Note
You can only select a point on another object in the scene. Selecting a point in 'space' is not a
valid option. To reposition an object into 'space', you can override the items Transform. See
Section 8.6.3, “ Overriding Transforms ” for details on how to do this.

5.
Click Transform Objects again to continue rotating the object about point 2, by the specified angle
(rotate selected object by 90 degrees about point 2 again, which results in object rotating from point
B to C).
See Section 8.7.3, “ Resetting Items' Positions ” for information on returning an object back to its original
position.
13.3.3. Measure Options
JetStream allows you to configure the appearance and selection style of the measure tools and the
measurement drawing in the main navigation window.

13.4. Hyperlinks
Hyperlinks are an extremely useful review tool to allow you to access non-graphical information through
the graphical interface of JetStream. As well as hyperlinks being converted from the native CAD files you
open in Roamer, you can also "override" an item's hyperlinks by attaching multiple additional hyperlinks to
it. Because hyperlinks are treated as a property by JetStream, they can be searched on with the Find
Items tool and displayed in the Properties bar. They are also saved into JetStream files so that as the
model changes, the links remain for you and others to view.
Hyperlinks are categorized so that you can switch them on and off by category, and they can be anything
internal (such as a viewpoints or selection set) or external (such as a web page, script, or spreadsheet) to
JetStream. By turning on hyperlinks in the main navigation window, you can simply click on the link to
activate it. Hyperlinks can be displayed as a text description, or as an icon and can also optionally have
leader lines pointing to points on the item to help you identify which item has the link attached.
To turn on hyperlinks
•

on the Workspace toolbar.
or
•
Go to Tools, Hyperlinks
13.4.1. Adding Hyperlinks
An item can have multiple hyperlinks attached to it, although only the default hyperlink (the one at the top
of the list) can be displayed in the navigation window at one time. The default is the link that will be
followed when clicked.

Hyperlinks Categories
Hyperlinks can be categorized so that you can group them to distinctly display or not display in the main
navigation window at one time. The seven default categories are:
•
Hyperlink
•
Tag
•
Viewpoints
•
Clash Detective
•
TimeLiner
•
Selection sets
•
Redline tags
Note
The Clash Detective and TimeLiner categories are only available if you have a valid license for
these plugins.
Tags are just hyperlinks that are displayed by name rather than by icon in the navigation window. The last
three of these categories are defined by JetStream and so you cannot assign a hyperlink to one of these
categories, other than by setting up a viewpoint, a selection set, or a Clash Detective result.
Use the Hyperlinks Options to select which categories are displayed when hyperlinks are turned on.
To add a new category, simply type in the name of the category into the Category box on the Add
Hyperlink dialog when you are adding or editing a hyperlink.
13.4.2. Displaying Hyperlinks
To turn on hyperlinks
•
Click Hyperlinks
on the Workspace toolbar.
or

Go to Tools, Hyperlinks
Hyperlinks are drawn as icons in the main navigation window and tags as text. Clicking on a hyperlink in
the main navigation window will follow the link and right clicking on it will open a context menu offering
you the options of Follow Hyperlink, Edit Hyperlink (see Section 13.4.4, “ Editing Hyperlinks ”) or
Select item containing hyperlink, which will select the item onto which the hyperlink is attached.
Attachment Points
Hyperlinks and tags are by default attached to the center of their owner's bounding box, but you can
override this with more convenient attachment points. When adding or editing a hyperlink, you have the

Reviewing
option of adding attachment points, as described in Section 13.4.1, “ Adding Hyperlinks ”. If you add more
than one attachment point, the hyperlink will be displayed attached to the closest attachment point to the
camera during navigation. This allows you to set up hyperlinks so that they are always available for
following when drawn in 3D mode during navigation, rather than disappearing behind objects. Leader
lines will be drawn from the attachment point to the hyperlink. The size of these lines can be defined in
Hyperlinks Options.
13.4.3. Following Hyperlinks
To follow a hyperlink, simply click on it in the main navigation window. If multiple hyperlinks are attached
to an item, the default hyperlink will be followed.
You can also follow one of the non-default hyperlinks attached to an item by selecting the item and going
to Review, Hyperlinks and selecting the hyperlink from the list.

Each hyperlink is a member of a category. This enables you to easily manage sets of hyperlinks. Use
the Visible check box to switch a category on or off in the main view. Some categories also have
comments associated with them. Use the Hide Icons Without Comments check box, if available, to
do exactly that - only draw hyperlinks that have a comment attached to it, so that you can see any
areas of issue in the model. See Section 13.1, “ Commenting ” for more information on comments.
8.
Use the Image and Text radio buttons for each category to tell JetStream how to draw that category
of hyperlinks. If text is drawn rather than the icon, the hyperlinks description is used as a tooltip style
text box in the main view instead of an icon.
9.
Click OK to set the options or Cancel to exit the dialog without setting them.
13.5. Smart Tags
Smart tags pop up information on the item hovered over by the cursor in a tooltip style window, without
having to select the item itself. The smart tag will disappear after a few seconds. This is a useful way to
quickly get information about an item in the main navigation window when navigation has ceased. The
default information shown is the name and type of the item, but you can define which properties to show
using the smart tags options.
Note
If the item hovered over doesn't have the property requested, smart tags will search up the
selection tree for a parent that does, so maximising the useful information you get.

13.6. Collaboration
The JetStream Collaborate tools enable multiple users to participate in a single design review session
across a Local Area Network (LAN). This utilizes the shared program features of Windows NetMeeting,
available to all Windows users.
All meeting participants require access to a JetStream .nwf or .nwd file, in a shared location. One of the
participants will 'host' the meeting and place a call to invite the others to join the meeting. Any of the
participants who have joined the meeting can take control and drive the session. All navigation performed
by the driver will be displayed in the main JetStream window on each participants machine. Any
viewpoints or markup (for example) added during the session can be updated on all participants
machines at the click of a button.
Note
If a collaborative review session, as outlined here, is not conducted in single room, then additional
tele-conferencing provisions could be necessary. This may be using the NetMeeting Whiteboard,
or your own telephone system.
To start a collaboration session:
•
Open the JetStream file that you wish to collaborate on from a shared directory (see Section 2.4, “
Opening Files ”).
•
Click Collaborate
on the Collaborate toolbar.
This will initialize Windows NetMeeting:

Note
The first time Windows NetMeeting initializes, a setup wizard will take you through the setup
process. You will need to enter your name and email address. When using NetMeeting on a LAN
you do not need to log onto a directory server, as these will not be available to you.
To place a call, inviting attendees to join:
•
Having initialized Windows NetMeeting, click Call
on the NetMeeting dialog.

The Place a call dialog is displayed:
•
In the To: box, enter the machine name or IP address of the machine you wish to join the meeting,
then click Call to send the invite, or Cancel to return to NetMeeting..
Once the person receiving the invite accepts this, both their name and yours will be listed in the
NetMeeting dialog.
Note
The above can be repeated to invite additional people to the meeting.
To accept an invitation:
•
When you are invited to join a meeting, the incoming call dialog is displayed:
•
Click Accept to join the meeting, or Ignore to decline the invitation.
Note
Once you have accepted a call, you will need to start your own collaboration session. See
Section 13.6, “ Collaboration ” [218] for more information.
During a collaboration meeting, anyone in the call can take control of the session and become the 'driver'.
The driver will control navigation of the shared model on all machines in the call.
To become the driver:

Click Drive
on the Collaborate toolbar.
Note
Upon clicking the drive button, all other users in the call will receive a message advising that you
are requesting control. They will have to answer Yes to this message if you are to drive
JetStream on their machine.
Although realtime navigation in JetStream can be performed on all machines in a call by one user, it is not
possible for review data such as saved viewpoints, comments and redlines, to be automatically updated
on all users' machines. This information can however be updated on their machines by refreshing the
model. This refresh process can be performed on one users machine and refresh all machines in the call.
To refresh all attendees machines:
•
Click Refresh
on the Collaborate toolbar.
13.7. SwitchBack
SwitchBack allows the current view of the currently loaded file to be sent back to AutoCAD (version 2004
or later) or MicroStation-based CAD products.
Note
The native CAD package must be installed on the same machine as JetStream for SwitchBack
to work.
AutoCAD (version 2004 or later)
•
For AutoCAD (version 2004 or later) or products based on it, first open the product in the usual
manner and load the nwexport application. This can be done easily by running the nwload command
in the command line. If SwitchBack needs to be available whenever AutoCAD is run, nwexport can
be added to the set of startup applications in AutoCAD.
•
Once the CAD package is running, and nwexport has been started, selecting an object in the scene
will allow the SwitchBack command to be selected either from the Review menu, from the right-click
context menu of the object, or, if a Clash Detective license is available, via the SwitchBack button on
the Results tab. Selecting SwitchBack then takes the current JetStream camera view back to the
CAD package.
Note
See the Clash Results section in the Clash Detective documentation for more information on
taking clash results back to the originating CAD package.
•
Switching back to AutoCAD whilst an object is selected will not only set the view in AutoCAD, but
also select the object. Selection of objects is done by entity handle, therefore, you must have Convert
Entity Handles option enabled when files are loaded into JetStream.

Reviewing
•
Some objects cannot be selected in AutoCAD (for example, blocks) which may mean that running
SwitchBack may be unsuccessful with a given selected object. If this is the case try selecting further
up the object tree and trying again.
MicroStation (/J and v8)
•
For MicroStation (/J and v8) or products based on it, first prepare MicroStation by loading the
JetStream exporter "mdl load nwexport5".
•
To get nwexport to load automatically when MicroStation is run, add "nwexport5" to the list of mdl
applications run automatically on startup.
•
Once the JetStream exporter has been run, selecting an object in the scene will allow the SwitchBack
command to be selected either from the Review menu, from the right-click context menu of the object,
or, if a Clash Detective license is available, via the SwitchBack button on the Results tab. Selecting
SwitchBack then takes the current JetStream camera view back to the first visible view in
MicroStation.
Note
See the Clash Results section in the Clash Detective documentation for more information on
taking clash results back to MicroStation.
•
If you wish to override the view used by SwitchBack, use the "nwview <view number>" key-in
where view number is the visible window in MicroStation. This view setting is not saved between
sessions.
•
Switching back to MicroStation whilst an object is selected will not only set the view in MicroStation,
but also select the object. Selection of objects is done by element id (MicroStation v8) or DMRS value
(MicroStation /J).

Chapter 14. Interface
The JetStream interface is fairly simple. Most features are accessible from the control bars, which can be
turned on or off from either the View, Control Bars menu, or by right clicking on any of the displayed
toolbars. All the control bars are dockable and a useful hint is to hold down the Control key when moving
a dialog if you do not want the dialog to dock. It is also a good idea to right click on dialogs to discover
features that are not at first glance obvious.
JetStream has the concept of what unit the scene is presented in. This is most useful when measuring
items, setting tolerances for clash detection, or sizes of textures. There is a single scene unit that is set
from Tools, Global Options, Display Units and this unit is used throughout the interface whenever
appropriate.
You can also set a profile to determine how complex the interface is and which parts are available to the
user. See Section 14.11, “ Profiles ” for more information on this feature.
In the lower right hand corner of the interface there are four performance indicators, that give you
constant feedback as to how JetStream is performing on your machine.
•
The progress bar under the left hand icon (pencil) indicates how much of the current view is drawn, i.e.
how much drop-out there is in the current viewpoint. When the progress bar is at 100%, the scene is
completely drawn, with no drop-out. The icon will change color when it is working. Whilst the scene is
being drawn, the pencil will change to yellow. If there is too much data to handle and your machine
cannot process this quickly enough for JetStream, then the pencil will change to red, indicating a
bottleneck.
•
The progress bar under the central icon (disk) indicates how much of the current model is loaded from
disk, i.e. how much is loaded into memory. When the progress bar is at 100%, the entire model,
including geometry and property information, is loaded into memory. The icon will change color when
it is working. Whilst data is being read, the disk will change to yellow. If there is too much data to
handle and your machine cannot process this quickly enough for JetStream, then the disk will change
to red, indicating a bottleneck.
•
The progress bar under the right hand icon (web server) indicates how much of the current model is
downloaded, i.e. how much has been downloaded from a web server. When the progress bar is at 100
%, the entire model has been downloaded. The icon will change color when it is working. Whilst data
is being downloaded, the web server will change to yellow. If there is too much data to handle and
your machine cannot process this quickly enough for JetStream, then the web server will change to
red, indicating a bottleneck.
•
The field to the right of the icons reports the amount of memory currently being used by JetStream.
This is reported in Megabytes (MB).
The view menu gives you control over the JetStream interface. It allows you to hide or reveal control bars,
customize the toolbars and status display, and split the current view into several smaller views. It also
allows you to display statistics about the currently loaded scene.

Note
The recording and playback of animations will occur in the most recently used view. Each
separate view remembers the navigation mode being used.
14.6. Full Screen Mode
Selecting Full Screen or pressing the F11 key puts JetStream into Full Screen mode; the main 3D
navigation view takes up the full screen with no interface showing. Pressing the F11 key for a second time
turns full-screen mode off. Full screen mode will always go to full screen on the primary display. If two
monitors are available, the interface can be placed on one whilst the main 3D view renders in full screen
on the other.
14.7. Sizing of Navigation Window
JetStream allows you to specify the size of the main navigation window. This can be of particular use if
you are composing a scene for image or animation export. By setting the window size to the same
proportions as your intended output, you can visualize exactly how it will result.
Explicit sizing of the main navigation window

calculated from the aspect ratio of the current view.
Click OK to set the window size, or Cancel to return to JetStream without changing it.
14.8. Stereo Rendering
Stereoscopic viewing in JetStream allows the viewing of the 3D model through stereo-enabled hardware,
including active and passive stereo viewing glasses in conjunction with both CRT screens and dedicated
projectors.
This feature requires the host computer have an OpenGL graphics card with stereo support. If this
hardware is available, and has the correct driver and display settings, stereo can be turned on by
selecting the View, Stereo menu option, otherwise this option will be greyed-out.
Note
Some drivers require stereo to be explicitly enabled in the driver and may require lower color or
resolution settings before stereo becomes available.
Selecting this menu option puts the video output into stereo mode; the view will look blurred without the
correct glasses being worn. If the camera is in orthographic mode, it will need to be set to perspective for
the effect to work correctly.
Note
As the view for each eye has to be rendered separately it is not possible to support incremental
filling in of detail in stereo mode. The detail appears when rendering is complete. Progress can be
seen using the bar in the status area, and it is still possible to interrupt and start interacting again
at any time.

Sliding the Out of screen bar, when enabled, and when using a focal point based navigation mode
(examine, orbit, turntable, etc.), will position the model so that parts closer than the focal point appear
in front of the screen, with the rest behind. The slider controls the balance, moving objects more or
less out of the screen. When using any other navigation mode (walk, fly, etc.), the focal point is set so
that any avatar will be level with the screen. Objects between you and the avatar will appear in front
of the screen.

The number of each type of element is listed together with which have been ignored or processed in
creating the scene.
14.10. Units
JetStream has the concept of what unit the scene is presented in. This is most useful when measuring
items, setting tolerances for clash detection, or sizes of textures. There is a single scene unit that is set
from the Global Options dialog and this unit is used throughout the interface whenever appropriate.
There is a default unit setting for each file type so that when files are opened, they are scaled
appropriately to the scene's units. They can, of course, be rescaled after if the units turn out to be wrong
for the scene.

All items on this menu are explained in other chapters, except for the Compare tool, which is described
below.
15.1. Comparing Models
The Compare tool becomes available when exactly two items are selected. These can be any types of
item, but the compare tool is most useful when comparing two versions of the same model. During the
comparison, JetStream will start at each item and recursively travel down each path, as seen in the
standard selection tree, comparing each item it comes across in terms of the criteria requested.
When the comparison has finished, you have the option of saving the differences as Selection Sets with
comments describing the differences in more detail.
Comparing two items
1.
Select exactly two items in the scene (see Chapter 6, Selecting Items for more information on how to
do this).

The Compare dialog is displayed
3.
In the Find Differences In section of the dialog, check all the boxes of the criteria that you want
JetStream to compare for differences between the two items. Overridden Material and Overridden
Transform relate to changing the color and/or transparency in JetStream and changing a file's origin,
scale or rotation since loading into JetStream, so these are unchecked by default. All the other
criteria relate to properties of items from the original CAD model.
4.
Check Save as selection set if you want to save the selected items that you are comparing between
as a selection set. You can then use this for later comparisons between the same items.
5.
Check Save each difference as set if you want to save the resulting differences found in the
comparison between the two items as a selection set for later analysis. The selection set will also
have a comment attached detailing the differences in more depth.
6.
Check Remove old results if you want to remove any selection sets resulting from a previous
comparison, in order to reduce confusion when looking at the results.
7.
Check Hide matches if you want to hide all items that turn out to be the same in the comparison,
when the comparison finishes. To show them again, reset all hidden items.
8.
Check Highlight results if you want to highlight each resulting difference with a color override, when
the comparison finishes. Reset the color using the reset material command.
9.
Click OK to start the comparison, or Cancel to return to JetStream without making any comparison.
At any time during the comparison, you can click on Cancel on the Exporting dialog to abort the

Chapter 17. DataTools
This feature is used to link Object Property elements in JetStream to fields that exist in a table within a
database. Any database with a suitable ODBC driver is supported, and properties contained within
database tables can be brought through and shown on the Properties control. If an object in a scene has
associated database properties, clicking on that object will show the properties in a separate tab.
Data linked from a database can also be included in any searches using the Find tool, and can also be
used within Clash Detective as part of the clash criteria. See Section 7.2, “ Finding Items ” for more
details on how to use the Find tool, and the Clash Detective book for more information on clashes and
clash criteria.
17.1. DataTools Links
To allow object data to be read from a database, a link between the model and the database needs to be
set up. This link can be set up in two places; Global Options and File Options. Both places allow the
same settings to be set up and database links in both places exist in tandem. Having the two locations
gives the option of setting up a single set of database links in Global Options for multiple files to access,
whilst allowing files to have their own individual database links within File Options.

•
Select your ODBC Driver from the drop-down list box and click on the Setup... button to setup that
driver. The driver will walk you through the setup options. If you have difficulties setting up your
connection details, contact your database administrator.
The box underneath will show the connection string.
Note
This is editable, though should only be changed with care. Under most circumstances this can be
left alone.
Some examples are:
•
Connection string: Selecting a database with a certain name (test.mdb) that is always next to the
model file (as in the resultant NWD/NWF not the original):
DBQ=%pushpath(%poppath(%currentpath),"test.mdb");DRIVER={Microsoft Access Driver (*.md
•
Connection string: Selecting a database with the same name as the original model file (e.g.
AutoPlant):
DBQ=%join(%removeext(%removepath(%sourcepath)),".mdb");DRIVER={Microsoft Access Driver
•
The Hold open for application lifetime check box, when checked, keeps the connection to the
dbase open whilst JetStream is open, and only closes it on exit.
•
The SQL String must always start with SELECT, and is used to connect to a table within the
database. Set up the query for the table by writing the SQL String.
Some SQL String examples include:
•
SQL String: Selecting all columns from table Test whilst requiring that the column called Entity
Handles matches a category/property pair called Entity Handle/Value and the column called File
Name matches the original filename of the drawing:
SELECT * FROM Test WHERE "Entity Handle" = %prop("Entity Handle","Value") AND “File Na
Here the path and the extension of the file name are being stripped so a file like
c:\model\3rdFloorDucts.dwg would come out as 3rdFloorDucts.
•
SQL String: Selecting two columns from table Test whilst requiring that the column called Entity
Handle matches a category/property pair called Entity Handle/Value:
SELECT Name,Part FROM Test WHERE "Entity Handle" = %prop("Entity Handle","Value");
•
SQL String: Selecting all columns from table Test whilst requiring that the column called Value is
within a certain range given by two category/property pairs:

DataTools
SELECT * FROM Test WHERE Value BETWEEN %prop("Pressure","Minimum") AND %prop("Pressure
The full Tag list includes:
Property tags
•
%prop("category","property") - Property of the currently selected object. Category is the name of
the tab in the property windows (e.g. Item or Entity Handle) and property is the name of the
property in that tab. (e.g. Value or Layer)
•
%intprop("category","property") - Property of the currently selected object. This is the same as the
previous tag except instead of using the publicly visible category and property name use the
internal JetStream names. The benefit of using internal names is that they are not language
dependent. [This is advanced tag that will make more sense to people familiar with the JetStream
API]
File/Path tags
•
%sourcepath – This tag represents the full path and filename that the currently selected object
comes from. Even when a collection of model files have been combined into a single NWD file this
tag will still remember the path and filename of the original model file.
•
%currentpath - This tag represents the full path and filename of the currently loaded model. If you
currently have an NWF or NWD loaded that contains many other models it will just return the path
and filename of the top level NWF/NWD.
File/Path Manipulation Tags
•
%removeext("text") – If the provided text includes a filename with an extension this tag will remove
the extension.
•
%removepath("text") – If the provided text includes a path and filename this tag will remove the
path and just return the filename.
•
%poppath("text") – If the provided text includes a path this tag will remove the top level. If it the text
also includes a filename that will count as the top level and be removed. [e.g. %poppath(“c:\temp”)
becomes c:\ and %popath(c:\temp\readme.txt”) becomes c:\temp]
•
%pushpath("text1","text2") – If text1 is a path and text2 is a file or folder name then text2 will be
added onto the path in text1. [e.g. %pushpath(“c:\test”,”model.nwd”) becomes c:\test\model.nwd]
String Manipulation Tags
•
%join("text","text") – This tag simply joins the two pieces of text together. [For example
244
www.cadfamily.com EMail:cadserv21@hotmail.com
The document is for study only,if tort to your rights,please inform us,we will delete
DataTools
%join(“c:\”,”model.nwd”) would return c:\model.nwd]
Note
Tags must not contain white space between the brackets (unless enclosed by quote marks), so
%prop("EntityHandle","Value")
works, but
%prop("EntityHandle", "Value")
does not.
•
Once the string is complete, clicking anywhere in the Fields box brings up a new edit control. Type in
the name of a field from the table accessed by the SQL String. Pressing enter automatically copies
this name into the display name. This display name is the text that appears in the database tab in the
Properties control; click on this display name to alter it. Continue to fill this in until the table contains all
the information required to be seen.
Note
All file-based connection information is saved inside the project NWF or NWD. The global
connection information is saved on the local machine. If the associated database is available on
loading the NWF/NWD file, the link will automatically establish itself when an object is selected.
On selecting an object, if the database is available, and there is data associated with the object,
JetStream will create an appropriate database tab in the Properties control and show the
appropriate data as set up in the connection details.
If a Publisher license is present, Object Properties can be extracted from a database connection
and embedded as static data within the published NWD file. See Section 4.1, “ Publishing from
Roamer ” for more information.

Glossary
Glossary of technical terms relating to JetStream Roamer.
Display Terminology
Average Frame Rate
This shows the current measured frame rate, averaged over the last
second.
Average Frame Time
This shows the time taken to render the last frame.
Average Triangle Rate
This shows the rate at which triangles are being rendered and is a
measure of how well your graphics card is working.
Culling
Culling is a process for determining items not to draw during the render
of a scene. JetStream does a level of prioritized culling with the drop-out
method of rendering interactive scenes, but you have a certain level of
control over other aspects of culling such as backface, near and far
planes.
Drop-Out
In order to maintain interactivity and guarantee a user-defined frame
rate, JetStream only renders what it can in the fraction of a second it has.
The remainder is "dropped out", or not rendered. However, JetStream
prioritizes what is rendered and what is dropped out based on size of the
item's bounding box, distance from viewer and size on screen, so only
the less significant items in the scene are dropped out. Once navigation
has ceased, the scene continues rendering until all items are visible.
Frame Rate
The frame rate is the number of frames per second (FPS) that are
rendered in the main navigation window. JetStream guarantees a
user-defined frame rate in order to maintain interactivity.
Export Terminology
These are terms specific to JetStream that are used in relation to exporting.
Codec
Codec stands for "COmpression-DECompression" and is a program that
compresses and decompresses animations when creating and playing
back .avi files. Codecs are installed independently of JetStream and are
available when installed on your Windows™ system and the same codec
that was used to create an .avi file is required to play it back.

.nwc Cache Files
When any native CAD file file is opened or appended, JetStream
Roamer creates a cache file (.nwc) if the write cache option is set. When
the file is next opened or appended, JetStream Roamer will read data
from the corresponding cache file rather than re-converting the original
data if the cache is newer than the original file. If the original file is
altered, JetStream Roamer will re-create the cache file when it is next
loaded. Cache files speed up access to commonly used files. They are
particularly useful for models made up of many files of which only a few
are changed between viewing sessions. Cache files can also be
exported from some CAD applications where a native file reader is not
available with JetStream Roamer. Cache options can be edited from the
Global Options dialog box under the Tools menu.
.nwd Published Data Files
Published .nwd files are useful when wanting to take a snapshot of the
model at a certain time. All the geometry and review information is saved
into the .nwd file and cannot then be changed. Published .nwd files can
also contain information about the file, as well as being able to be
password protected and time-bombed for security. These files are also
very small, compressing the CAD data by up to 80% of the original size.
Published .nwd files are useful when issuing models for viewing by
others with the NavisWorks Freedom free viewer, as well as being
appendable themselves into Roamer to build up a larger scene.
.nwf Review Files
Review files are useful when using the native CAD files appended into
JetStream Roamer. They store the location of the appended files, along
with any design reviews made in JetStream, such as comments,
redlines, viewpoints, animations and so on.
If a group of files is appended into a JetStream scene, and saved as an
.nwf file, then on re-opening this .nwf file later, once the original CAD
files have been changed, the updated CAD files will be loaded into the
scene for review.
External References
External references (sometimes called reference files or "XRefs") are
shown in Roamer selection tree as an inserted group. Roamer looks for
the externally referenced files in the same place as AutoCAD or
MicroStation would.
If the Unresolved XRef dialog box is shown, then this link has somehow
been broken and the referenced files need to be relocated to where
AutoCAD or MicroStation would expect them to be.
If these XRefs are not important for the current session, then you can
Ignore the reference and the file will load without that XRef inserted.
Similarly, Ignore All will load the file without any unresolved XRefs.
You can also use the DWG/DXF and DGN options in the Tools, Global
Options dialog to set whether external references are loaded or not,
giving you more control over file appending into JetStream.
Faceting Factor
During an export from a CAD package to .nwc, or while Roamer is
reading a native CAD file, decisions must be made as how a curved
255

Glossary
surface is reduced to flat facets. For most applications and file formats,
you have control over the level of faceting that takes place.
All items, no matter what their size, will use the same faceting factor and
so have the same number of sides to curved entities. Therefore, you
need to experiment a little with different values to account for the size
that these items will appear on screen.
The faceting factor must be greater or equal to 0, where 0 results in the
faceting factor being turned off. The default value is 1, if you double the
value you get twice the number of facets, if you halve the value you get
half as many facets. Larger faceting factors will result in more polygons
to a model and larger JetStream files. There is little point having a large
faceting factor if these curved entities are golf balls viewed from 200
yards!
For AutoCAD exports, the faceting factor is set from the NWCOPT
command, MicroStation's faceting factor is set from Options, which is
available from the NWCOUT export dialog, and the option to set the
faceting factor on reading CAD files is found by choosing Tools, Global
Options, and the relevant options tab.
Max Facet Deviation
Maximum facet deviation is used in conjunction with faceting factor to
ensure that larger objects, with too large a deviation from the original,
have additional facets added. If a difference greater than the entered
value is found in a model it adds more facets. The values are measured
in the model units.
Where d is greater than the maximum faceting deviation value, more
facets are added to the object.
If the max faceting deviation is set to 0, then this function is ignored and
just the faceting factor is used.
Shape Merge Threshold
MicroStation shapes are polygons that can have 3 or more vertices.
They're often used to model more complex objects which can waste
memory. So, JetStream merges all shapes on the same level or in the
same cell and with the same color into a "Shape Set" if these shapes
have less than or equal to the number of vertices given by the Shape
Merge Threshold.
Selection Terminology
256

Glossary
These are terms specific to JetStream that are used in relation to selecting items.
Composite Objects
A composite object is a group of geometry that is considered a single
object in the selection tree. For example, a window object might be made
up of a frame and a pane. If a composite object, the window object would
be both the frame and the pane and be selected all at once.
Instances
An instance is a single object, which is referred to several times within a
model, for example a tree. This has the advantage of cutting down on file
size by not unnecessarily repeating an object.
Item Name
The original CAD or JetStream assigned identifier. Any item can have a
name and this name will usually come from the original CAD package
that the model was created in.
Item Type
Every item in JetStream has a type. Examples of types are reference
files, layers, instances (sometimes called inserts) and groups. Every
CAD package also has a number of geometry types, for example,
polygons, 3D Solids and so on.
Selection Resolution
The selection resolution is the level in the selection tree you start
selecting at. You can cycle through items in the tree by holding down the
shift key during a selection.
User Name and Internal Name
Each category and property name has two parts - a user visible string
which is localized and an internal string which isn't and is mainly used by
the API. By default when matching names in the Smart Tags and Find
Items dialogs, both parts must be the same, but you can use the flags to
match only on one part. You might use ignore user name if you wanted
to match something irrespective of which localized version was being
used.
Viewpoint Terminology
Angular Speed
The speed that the camera moves when turning right and left in any
navigation mode.
Aspect Ratio
Aspect ratio is the proportion of x-axis to y-axis size. For example, in
exporting a bitmap of a viewpoint, maintaining the aspect ratio would
keep the proportion of the view even if the number of pixels was
different.
Anti-aliasing
Anti-aliasing improves image quality by softening the jagged edge
appearance of sharp lines. 2x to 64x refers to the extra number of frames
that are required for the anti-aliasing process. The greater the number of
frames, the finer the effect, (with the consequent increase in rendering

time).
Camera-Centric
Navigation modes in which the camera is moved around the model (c.f.
model-centric).
Field of View
The field of view of a camera is the angle that the camera can see. A
large field of view will fit more into the view, but will look distorted and a
small field of view will tend to make the view more flat, tending towards
an orthographic view. There are two fields of view in JetStream - vertical
and horizontal. Editing one will change the other and the two are related
by the viewpoint's aspect ratio.
Focal Point
The focal point is the position in 3D space that the camera will rotate
around or zoom into in examine, orbit, turntable and zoom modes.
Model-Centric
Navigation modes in which the model is moved in front of the camera
(c.f. camera-centric).
Roll
The roll of the camera is its angle around the viewing axis. This cannot
be edited in a navigation mode where the world up vector stays upright
(walk, orbit and turntable).
Saved Attributes
Each viewpoint can optionally save the state of its hidden and "required"
items, as well as any material (color and transparency) overrides. Then,
on recalling the viewpoint, those same items are re-hidden, re-made
required, and the materials reinstated. This can be useful in the creation
of animations when dragging on viewpoints onto an empty animation.
Tilt Angle
This is indicated in the scene's units below (negative) or above (positive)
horizontal (0) at the base of the tilt bar.
World Up Vector
The direction that JetStream considers "up" is called the "world-up
vector". This is maintained in the walk, orbit and turntable modes.
