If you are looking at exporting data from your design application such as Civil 3D Design, Plant 3D, Revit etc into Navisworks, you will need to install the appropriate Object Enabler. Whilst you can import your model in it native file format, it will be at full size. If you don’t download the enabler, you will not be able to export your design as a Navisworks NWC file (which reduces files size by over 80%).
Autodesk has a one stop page for all applications. You will need to access the Object enablers and choose the application you use.
It’s also a great location for Navisworks updates and downloads.
