unchecked leaves the faces as separate items in JetStream.
4. 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.

7.2. 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
7.2.1. 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
