I really want to support open-source CAD, but it's so hard to take FreeCAD seriously. It reminds me of POV-Ray, which was (and still is) a parametric raytracer. An impressive feat of engineering completely derailed by the choice of a "UI" paradigm that made the simplest things unreasonably hard.
Designing 3D parts is hard enough, and while parametric modeling has uses... come on.
Parametric modelling is not the cause of the bad UI in FreeCAD, Fusion 360, Onshape, etc are also parametric. No, the main problems (last I tried it around 1.0) were that it had a clunky UI and that it was buggy. It would refuse to chamfer or bevel edges for no apparent reason that other CAD software wouldn't have issues with. There were occasionally crashes. Editing previous steps would destroy the later steps much more often than in other CAD software. Etc.
I would love to go back to FreeCAD, but for now I'm using Onshape (I run Linux, so Fusion isn't an option).
