How to use OBJ, STL, PLY Files in MoI

Solidworks has a go at turning point clouds into nurbs surfaces. However, 1) it doesn't trim them - it leaves that for you to do and 2) at best it's just an educated guess.

If SW has difficulty with this, with the resources they can throw at it, then it is not likely that anyone else has a better solution.
