Ok I’m probably sticking to FreeCAD, not going switch to anything proprietary.

https://github.com/joachimhs/akse3d might be interesting too.

Most of the time redundant constrains are added automatically while drawing.

I never add more datum constraints that are necessary.

I’ve made like 50 designs with FreeCAD already, I think it got worse recently.

A cheap logic analyzer is really useful to have.
