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:
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.
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:
