There are constraint based CAD addons for blender, and the black art of Geometry node rendering pipelines to auto-generate objects/features. There is also the fact most of the system is open Python API based, and thus everything can be generated from code.

However, Blender was not meant to be a constraint based CAD/CAM package.

Solidworks still seems like the leader in offline mode, but parametric-everything FreeCad is evolving at an astonishing rate.

For critical professional work, gambling on opensource is still inappropriate most of the time. =3

I'm keen on trying freecad 1.0. After professional training in engineering drafting, I'm interested to see if I can get by with a lot more understanding of the processes.
