I'm looking for a 3d modeling toolkit for Ubuntu Linux to replace Autodesk Inventor, which I had been running on an old Windows box. As I am working on projects with others that use Inventor, parametric and constraint-based modeling as well as support for parts/assemblies and 2d drawings generated from parts/assemblies are a must.
Interoperability with Autodesk file formats would be useful but is not necessary in my case.
I've tried Inventor itself through Wine (garbage), VirtualBox (fails to start in spite of 3d graphics support, also I don't have enough RAM to launch a VM and the software), and am using it on an older Windows box that desperately needs to be retired (due to aging hardware).
If anyone has any suggestions that would work that would be much appreciated.
