3. Select the Convert Hidden Items check box if you want to read hidden entities from the .skp file.
They will be converted but hidden in NavisWorks.
4. Select the Merge Faces check box if you want to reduce the complexity of the model as seen in the
selection tree by interpreting a body as a single item consisting of a group of faces. Leaving
unchecked leaves the faces as separate items in NavisWorks.
5. Select 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 NavisWorks.
6. Click OK to set these options or Cancel to exit the dialog without setting them.
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. Autodesk NavisWorks Simulate 2009 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 NavisWorks. 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 NavisWorks instead.
