Autodesk/Navisworks Tech Support - NWC/ NWD or NWNAVIGATOR command not working in AutoCAD

The NWCOUT / NWDOUT or NWNAVIGATOR commands are not working on certain AutoCAD-based applications. You also notice that performing an Add/Remove Feature with the NavisWorks installer does not resolve this issue.


This situation can arise when AutoCAD has been installed after the NavisWorks application. To resolve this issue you may need to manually add the .arx file from the installed program directory.

Follow these steps to resolve the issue:

  1. Launch your AutoCAD application.
  2. Type APPLOAD in the command prompt.
  3. Click STARTUP SUITE -> Select ADD.
  4. Browse to
    • For AutoCAD 2009 products:
      C:\Program Files\Common Files\Autodesk\NavisWorks\2009\nwexport2009
    • For AutoCAD 2008 products:
      C:\Program Files\Common Files\Autodesk\NavisWorks\2009\nwexport2008
  5. Select NWEXPORT2009.arx and click ADD.

Perform the same steps to add the file NWNAVIGATOR.ARX.

This will add the necessary .arx files to the application startup suite and the NavisWorks features will be available in AutoCAD.
