I've been using various CAD programs, and IMO, FreeCAD UI/UX is quite ok. If you are Inventor or Solidworks user and try to switch to SolidEdge for example, it won't be easy. Not to mention some others like VariCAD (~30 years old professional MCAD)
There are many issues with FreeCAD being OSS alternative to professional MCAD software, but UI/UX is not one of them
