Yes. I agree with Danny. I think the Parasolid (file format) is quite popular in CAM industry and it is often used as a geometric modeling kernel in CAM packages as well. So smooth interoperability between MoI and CAM would be ensured.

Another way to ensure a good result of creating a tool path geometry from a STL file would be to let users set up a "maximum distance to surface" for export to STL file (it is also on wishlist).
