I'm in the same boat. Would love to be able to use Fusion in linux, especially with Apple dropping OpenGL support. Last I read they were looking to move the app to web-based and be platform agnostic.

I tried the web beta version and it's pretty limited and super slow. Nothing compared to OnShape but OnShapes license, policy and direction has been so bad that I dropped them pretty much after the official release (I used them during the beta phase).

I use FreeCAD. It is sometimes annoying, but much better than any alternative I've tried.

For more programmatic CAD, OpenSCAD is also good.

I use FreeCAD and OpenSCAD (especially "automated" file generation) and like what they stand for but unfortunately neither really compares to a standard CAD program. Maybe I'm too used to the big three CAD software.

AND you can script them with Python!
