Entering NWNAVIGATOR at the command line gives the dreaded "Unknown Command" message. This should display a Navisworks viewer inside AutoCAD (or vertical) after you install the Navisworks plug-in.
Here are two reasons the Navigator may not be displayed.
- AutoCAD 2010 does not ship with the VBA utility which is needed by the Navigator to function. To download and install the VBA utility review my prior post: http://avatechsupport.blogspot.com/2009/04/why-isnt-my-vba-installed-with-autdesk.html
- The plug-in that installs the Navigator is not supported on a 64-bit system and just won't install/run. Autodesk is aware of this issue.
