Hi Kenmo , re: import SketchUp models - that isn't really feasible because SketchUp files contain only polygon mesh data, not CAD surfaces and solids.

Something that looks like a sphere for example in SketchUp is not a single sphere surface like it is in a CAD program. It's actually made up of a lot of little triangles.

Moi is not designed to work with that type of polygon mesh data, you would need to use a polygon mesh editing program to work on SketchUp models, not MoI.
