What 3D modelling were you doing that couldn't be done on linux?
Mostly having software better than FreeCAD, AKA everything that exists on Windows and macOS.
Fusion360 doesn't work on Linux. Or at least I tried multiple times and couldn't get it to work
Really? I recall installing it 3 years ago, and aside from some oddities with popups, it worked just fine. I think it was this script [0]. I don't know if they broke it, I switched to OpenSCAD, which meets my needs.
