Lost in translation

CAD file formats are a mess.

I’m trying to get a part made in Autodesk Inventor into Mastercam.

IGES is borked. Half the surfaces don’t come in.

SAT has a version mismatch or something, and it refuses to import.

I don’t have a license for STEP import, apparently, and STL (even if it isn’t NURBS) is messed up like IGES.

This is obviously an attempt by Autodesk to dominate the world.
