FreeCAD is a 3D CAD tool with features and UI similar to Catia, SolidWorks or Solid Edge.

With CATIA being the gold standard tool that is used in aerospace, automotive, etc industries.

So FreeCAD is on a very great path.

(It also highlights how important the UI is. Everyone who every used a 3D CAD tool, can use FreeCAD in no time. On the other hand, everyone who used a polygon based 3D modeling like 3DMax or Maya will have a really hard time with the Blender and its very non-standard UI.)
