FreeCAD is "feature full", but ... bearer of bad news here (sorry):

   1. The UI is simply *awful*. Reminds me of the bad old days of Blender. Feels like a Motif style UI from the 90's TBH. Freecad needs to do what Blender did, bite the bullet hard and redo the UI from scratch to bring it into the 21st century.

   2. The underlying NURBS engine (OpenCascade) is what's best in the FOSS world, but unfortunately it can't hold a candle to the "kernels" (CAD lingo for engine) that power equivalent commercial offerings (Fusion, Rhino, SolidWorks, CATIA, etc...)

Finally, I really wish FreeCAD had an OpenSCAD-like domain specific language for modeling that can directly create NURBS (there is a kind of an OpenSCAD integration, but it can only do poly meshes).
