>Aspect Ratio allows you to set the height, and the width is automatically calculated from the aspect ratio of your current view.

Current View takes the width and height of your current view.

>Anti-Aliasing smoothes the edges of the exported images. The higher the number, the smoother the image, but the longer they take to export. 4x should be adequate for most situations.

NWF Files

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 overridescommentsredlinesviewpoints 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.

NWD Files

NWD Files

.nwd files are files published by JetStream Publisher and are snapshots of the model at a certain time. See 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.

   The NWD dialog box is displayed.

   

2. Uncheck the Enable check box if you wish to have no geometry compression.

3. Check the coordinates check box if you wish to reduce the precision of coordinates.

   Enter the value to which you wish coordinates to be precise to. The larger the value, the less precise coordinates will be and the smaller the .nwd will be.

4. Check the normals check box to reduce the precision of normals.

5. Check the colors check box to reduce the precision of colors.

6. Check the texture coordinates check box to reduce the precision of texture coordinates.

7. Click OK to set these options or Cancel to exit the dialog without setting them.

NWC Files

NWC Files

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 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.

   

2. Uncheck the Read Cache box if you wish to ignore any existing caches when opening a native CAD file.

3. Uncheck the Write Cache box if you do not wish to write a cache file the next time a native CAD file is loaded.

4. Uncheck the Enable box if you wish to have no geometry compression when .nwc files are written.

5. Check the coordinates box if you wish to reduce the coordinate precision.

   Enter the value to which you want coordinates to be precise to.

6. Check the normals box...

7. Check the colors box...

8. Check the texture coordinates box...

9. Click OK to set these options or Cancel to exit the dialog without setting them.

DWG and DXF Files

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 for more details.

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.

• Points and snap points

• Lines, polylines, circles, arcs with zero thickness.

• Named views.

• Layers.

• Colors.

• Blocks, inserts and multiple inserts.

• Groups.

• External references (xrefs).

• Hyperlinks.

• Entity handles.

• Attributes.

• Textures (requires a valid JetStream Presenter license).

• File properties.

Unsupported Entities

• Lights.

• Splines.

• Multi-lines.

• Linetypes.

• Dimensions and leaders.

• Raster bitmaps.

• Text or multi-line text.

• Construction lines (xlines and rays).

• Hatching.

DWG and DXF File Reader Options

Setting the .dwg and .dxf file reader options

1. Go to Tools, Global Options, DWG/DXF

   The DWG/DXF dialog is displayed

   

2. Enter the Faceting Factor (the value must be greater than 0). The higher the value, the more JetStream will facet rounded entities and therefore the smoother they will appear. See for more information.

3. Enter the Max Facet Deviation . This will facet entities to within the specified tolerance. See for more information.

4. Check the Split by Color check box if you want to be able to select parts of compound entities in JetStream. For example, a window object from Architectural Desktop may be split into a frame and a pane. If this check box is not checked, then you will only be able to select the window object as a 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 for more details).

6. Check the Merge 3D Faces check box if you want to reduce the complexity of the model as seen in the selection tree by interpreting ajoining faces with the same color, layer and parent as a single item. Leaving unchecked leaves these entities as separate items in JetStream.

7. Check the Merge Lines check box if you want to reduce the complexity of the model as seen in the selection tree by interpreting ajoining lines with the same color, layer and parent as a single item. Leaving unchecked leaves these entities as separate items in JetStream.

8. Check the Convert Off check box if you want to read layers that are switched off in .dwg and .dxf files. They will be converted but hidden in JetStream.

9. Check the Convert Frozen check box if you want to read layers that are frozen in .dwg and .dxf files. They will be converted but hidden in JetStream.

10. Check the Convert Entity Handles check box if you want to read entity handles as a property attached to the item in JetStream.

11. Check the Convert Groups check box if you want to retain the groups from .dwg and .dxf files, adding another selection level to the selection tree. See for more information on selecting objects and the selection tree.

12. Check the Convert XRefs check box if you want to convert any external reference files contained within the .dwg file. Unchecking this will give you more control over which files you append into JetStream.

13. Check the Merge XRef Layers check box if you wish to merge the layers of external reference files into those of the main .dwg file. Leaving this unchecked will keep the external reference file separate within the selection hierachy of JetStream.

14. Check the Convert Views check box if you want to convert the named views from the file into JetStream viewpoints.

15. Check the Convert Points check box if you want to read any points from .dwg and .dxf files. See for more information on how to display these in JetStream.

16. Check the Convert Lines check box if you want to read any lines and arcs from .dwg and .dxf files. See for more information on how to display these in JetStream.

17. Check the Convert Snap Points check box if you want to read any snap points from .dwg and .dxf files. See for more information on how to display these in JetStream.

18. The Loader for 2004 dwg combo box allows selection of which version of ObjectDBX is used when loading AutoCAD 2004 .dwg files. This allows you to select support for the correct version of object enablers that may be used within the file. Please note that once any particular version of ObjectDBX is loaded, which occurs during reading of a .dwg or .dxf file, that the version in use will not change until JetStream is restarted.

19. Check the Load Material Definitions check box if you want to load material definitions into JetStream from Autodesk Architectural Desktop .dwg files.

20. Check the Use ADT Standard Configuration check box to force reading of Autodesk Architectural Desktop .dwg files using the Standard display configuration. If unchecked, geometry and materials will be read in according to whether they are displayed in the currently saved display configuration.

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.

    Note

    For Autodesk Architectural Desktop materials to be read into JetStream Roamer, a valid Presenter license is required.

23. Clicking the Advanced button will open a dialog which giving you the option to read object information from various third party applications that are built on AutoCAD.

    

    Check those applications you wish to read information from.

24. Click OK to set these options or Cancel to exit the dialog without setting them.

DWF Files

DWF Files

Autodesk's DWF (Design Web Format) was specifically developed by Autodesk as a file format for architects, engineers, and GIS professionals to share design data. The JetStream file reader reads all 3D geometry, as well as textures and properties. A full list is given below.

Supported Entities

• All 3D geometry

• Texture maps (Requires a valid JetStream Presenter license)

• Texture coordinates

• Colors (per-vertex, per-face)

• Property fields

• Categories

Unsupported Entities

• 2D lines/plot sections

DWF File Reader Options

Setting the .dwf file reader options

1. Go to Tools, Global Options, DWF

   The DWF dialog is displayed

   

2. Enter the Faceting Factor (the value must be greater than 0). The higher the value, the more JetStream will facet rounded entities and therefore the smoother they will appear. See for more information.

3. Enter the Max Facet Deviation . This will facet entities to within the specified tolerance. See for more information.

4. Check the Extract textures check box to load in textures and environment maps associated with the file. Environment maps will not automatically be set in the scene, and will need to be manually set up in Presenter.

   Note

   For DWF texture maps to be read into JetStream Roamer, a valid Presenter license is required.

5. Click OK to set these options or Cancel to exit the dialog without setting them.

Bentley AutoPLANT Files

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 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.

3DS Files

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 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.)

• Wireframe meshes

• Lines, splines

• Points

• Background images

3DS File Reader Options

Setting the .3ds file reader options

1. Go to Tools, Global Options, 3DS

   The 3DS dialog is displayed

   

2. Check the Convert Hidden check box if you want to read hidden entities from the .3ds file. They will be converted but hidden in JetStream.

3. The paths of texture map files are not stored with the texture maps in the model so enter a semi-colon separated list of paths in Bitmap File Search Paths that the reader will search in when it finds texture maps in the model.

   Note

   For 3DS texture maps to be read into JetStream Roamer, a valid Presenter license is required.

4. From the Default Units drop-down, choose the type of units that JetStream will use when opening .3ds files. If the units turn out to be wrong, the model can be easily rescaled using the File Transform function (see for more details).

5. Click OK to set these options or Cancel to exit the dialog without setting them.

DGN and PRP Files

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 for more details.

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.

• Splines and B-spline curves.

• Lights.

• Levels.

• Cells and shared cells and their instancing.

• Colors and ambient, diffuse and shininess properties of materials from .pal and .mat palette and material files.

• Texture maps (requires a valid JetStream Presenter license).

• Reference files including aliases.

• Text will be converted into hyperlink tags (see for details on hyperlinks).

• Family, Part and Texture information from TriForma, and PDS object information from .drv files.

• DMRS and database linkage and association ID's.

Unsupported Entities

• Raster bitmaps.

• Dimensions and leaders.

DGN File Reader Options

Setting the .dgn file reader options

1. Go to Tools, Global Options, DGN

   The DGN dialog is displayed

   

2. Enter the Faceting Factor (the value must be greater than 0). The higher the value, the more JetStream will facet rounded entities and therefore the smoother they will appear. See for more information.

3. Enter the Max Facet Deviation . This will facet entities to within the specified tolerance. See for more information.

4. Check the Convert Hidden Items check box if you want to read hidden entities from the .dgn file. They will be converted but hidden in JetStream.

5. Check the Show Hidden Items check box if you want to show all entities in the .dgn file whether they are set as hidden or not. This option will only work if Convert Hidden Items is also checked.

6. Check the Convert Lines and Arcs check box if you want to read lines, splines, curves, arcs, circles or ellipses from the .dgn file.

7. Check the Merge Lines and Arcs check box if you want to reduce the complexity of the model as seen in the selection tree by interpreting adjoining lines etc. with the same color, level and parent as a single item. Leaving unchecked leaves these elements as separate items in JetStream.

8. Check the Convert Text check box if you want to read text from the .dgn file. Text will be converted into smart tags in JetStream.

9. Enter the Shape Merge Threshold into the box. See for more information on Shape Merge Threshold.

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 TriCAD while reading the .dgn files.

18. Check the Convert TriForma Data check box if you want to read object information from Bentley'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.

MAN Files

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 Principal Window. If they are not included in the Principal Window, they will have a color determined by their style.

• Light styles. Projector lights are treated as a Spot light without the transparent image.

• Material styles, both plain and most LightWorks Renderer materials. Materials using wrapped images locate their image files using the "Texture Path" specified below.

• Views. Perspective Views are read in as if 3-point Perspective; parallel Views are not read. A Section Plane in a MicroGDS View is set in the corresponding JetStream View.

• Layers. All layers are read, and made visible according to their status in the Principal Window of the MAN file.

• Instances.

• Object data structure.

Unsupported Entities

• Text primitives.

• Photo primitives.

MAN File Reader Options

Faro Scan Files

Faro Scan Files

Faro scan files can be read by JetStream Roamer. iQmod and iQwsp files are workspace files that contain a list of one or more associated iQscan files. The iQscan files must be located in a folder called 'Scans', located in the same directory as the workspace file.

Supported Entities

• Points.

Unsupported Entities

• No other entities are supported.

Faro Scan File Reader Options

Setting the Faro Scan file reader options

1. Go to Tools, Global Options, Faro

   The Faro dialog is displayed

   

2. Point colors for Faro files can be set to None where the points come through as white, and Intensity and Color where the points use the intensity or color values stored in the file.

   It should be noted that if Point colors is set to a higher level in the Global Options than are available in the file, then it will default to the highest available within the file. So for example if the Global Options are set to color, but only intensities are available in the file, intensities will be shown in the main view.

AutoCAD .nwc Exporter

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.

You can also publish .nwd files directly from AutoCAD if you have the Publisher plugin. For more details, refer to

Exporting .nwc files from AutoCAD

1. Type nwcout at the command line.

2. The standard WindowsSave 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 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 Files\'NavisWorks 5\'NWExport\'LwNw_Export.mnu , for AutoCAD 2000 based applications, this will be C:\'Program Files\'NavisWorks 5\'NWExport2000\'LwNw_Export.mnu , and for 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 for more details.

• Export .nwc

  See for more details.

• NavisWorks Export Options

  See for more details.

• Navigator

  See 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 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.

Revit .nwc Exporter

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.
