I have tried freecad a number of times to replace solidworks as a critical piece of closed source software in hardware development toolchains. I have always struggled. Yesterday someone spent an hour with me at a makespace saying... "FreeCAD has a different way of doing this/try realthunder branch/use symmetry condition/delete all conditions that coincide" ... it has been worth years of trying alone. When I started solidworks the reseller gave me a week of training - this is often why complex FOSS software gets a reputation for being clunky, because alone you will spend ages hunting a GUI button in a complex interface.

TLDR: Go outside, go to makespace or a FREECAD conference - meet other people who use open source software - its much easier to use/learn from others than alone.
