This has been out there a while, but I only just learned of it and thot I’d share: check out KOMPAS-3D LT v9 from Russian software firm ASCON. Its a free single-part-only (no assemblies) 3D parametric modeling tool. I’m currently downloading and will try it out at home. Its aparently similar to SolidWorks or Alibre. I’ll try to write a quick “review” if I get a chance.
Thot you might like to know about it, FYI. Always nice to have another option in the toolbox.
EDIT: Oh, yeah, and they’ve got reduced pricing for student users of the full “Pro” version now available.
