Navisworks file (.NWD) and fit check with assembly

I was given a Navisworks file (.nwd) that I need to see if my product fits as expected in the system.

Any thoughts on how I can do that? I have access to several CAD programs. I just haven't found a way to get the files together.

From what I read online at Autodesk, the NWD file is basically a viewer file (snapshot) so I feel I may be out of luck and I'll have to get with my customer and see if they can give me some other format.

Just curious if anyone has any experience.
