Comments about FreeCAD as an Alternative to SOLIDWORKS
It's free for both personal and commercial use
Unfortunately not usable, after several years of using freecad, I quickly saw its limits. It is not a parametric software, indeed the topological naming problem makes this software fundamentally broken. The realthunder fork fixes some of these problems. fork or not, some advanced actions are still impossible and the different workbench are too isolated, some objects created with a workbench can't be modified by another one.

AS far as I have tried, FreeCAD is the only FOSS alternative to Solidworks/Catia/PTC that has a funtional workflow. It is the best of a poor bunch.
