ExoticTofu Model Pack addon - Star Wars Fan Group

Almost everything in this is an Inventor file. You can import any of these into 3ds max assuming you have a version of Inventor, but the wire-frame topography will be compromised. This may create issues when trying to normal/uv map these models, but im sure the greater expertise of the community will figure out ways around it.

Key points
*you need inventor 2012 or newer to be able to import inventor files into 3ds. you can get a free student license for the latest version of inventor
*if you have inventor you'll get a preview of every model in the file before you open it
*the Executor 3dsmax file, which is included, is about 30 million polygons and is composed of over 2,000 separate objects when complete. it may be difficult to load or modify. When you open the file, you'll only see one half. you'll have to mirror the entire ship
*the date modified for all of these files stretches back 4 years or more, keep that in mind
