Chapter 10. Converting Files
With Autodesk NavisWorks Simulate 2009 you can open a wide variety of native CAD file types without
having to have the CAD application on your machine. Files read by NavisWorks include .dwg, .dgn, .dxf
and Inventor. For a full list of CAD files that NavisWorks can open, please refer to the web site
www.autodesk.com/navisworkssimulate. This site will also explain which entities are read by NavisWorks
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 NavisWorks 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, Autodesk NavisWorks Simulate 2009 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 NavisWorks but there are exporters available to export to the NavisWorks .nwc file format from these
applications. See “ File Exporters ” for more details.
