Working with 3d mesh data in Inventor

[KFree86]

Hi all. First ever forum post here so bear with me..

I am working on designing custom car parts and thought it would be great to have a 3d scan of a vehicle for reference while modeling in Inventor. I had someone come out and do some scanning for me and they provided me with .obj files. I am able to open, import, place them in an assembly. My problem is converting the mesh data to inch format as opposed to mm. I have tried importing and saving, then derive with a scale factor but when I do this the mesh just disappears.

I have searched quite a bit and really cant find any info on working with 3d meshes in Inventor. There must be a way to accomplish this...

Any help at all would be greatly appreciated!

Thanks
