"Not constraint based" = not CAD software.
Fusion 360 on the other hand is not a scratch-built product, but uses the same kernel as Autodesk Inventor, ShapeManager - which is based on ACIS, of which version 1.0 was written in 1985. That gives you an idea of how friggin hard it is to write a decent CAD kernel - all the commercial ones are decades old.
The only real free software CAD kernel is OpenCASCADE.
- rurban 6y agoThe best parametric 3D CAD kernel now has SolveSpace, and it's open source. Much better than ACIS and OpenCASCADE. It's very young though.
