Tried openscad and then cadquery for some geometry iteration projects and found them clunky. It wasn't just that I was missing a UI; the functions, constraints and geometry kernel weren't as powerful as onshape, which I've used a bit, and presumably light years behind fusion 360, which I haven't used.

Even freecad, a UI-based oss cad, is not quite ergonomic for a beginner-to-intermediate user, though it has come a long way in the past few years.

I'm excited for there to eventually be a good open source cad option, whether language-only or language-plus-GUI, but am also increasingly on team 'tools matter for your productivity'.

The great thing about OpenSCAD is that it makes it easy to programmatically model objects using cubes, cylinders, cones, and spheres by placing, stretching, and rotating them.

The awful thing about OpenSCAD is that one's ability to model in it is strongly bounded by one's fluency with mathematics and ability to use math to programmatically model objects using cubes, cylinders, cones, and spheres by placing, stretching, and rotating them.

The one tool I'm aware of which is looking at a new geometry kernel which I can recall is:

If you want a classical GUI based cad tool for 3D modelling, I'd suggest taking a look at solve space and dune3d

freecad with the new ui + its openscad integration is pretty good.

openscad in general is quite easy if you can functionally program

As someone who has been using FreeCAD starting in 2020, I can't tell any major differences. The problems are the same they have ever been. It's only the renderer that got a little bit more "sexy", but that is just looks.
