Earlier this year I did a post on importing Sketchup into Navisworks, and how great it works. So a clients asks, 'can you do the same from 3DsMAX to Navisworks 2013?'. The answer is no, geometry will export but all materials will be missing. Autodesk is aware of this bug and is working on it.
DWF works fine
I haven't tried this on 2014
