I use FreeCAD most of the time, but occasionally I'll also use OpenSCAD. It's a different way to think about drawings but in certain circumstances it seems easier.
Once freecad clicks, you'll love it. I ditched fusion when the locked my files behind their servers and said I was using it for commercial work (I was not). FreeCAD is the way
FreeCAD is basically the only decent FOSS, but if you want to swap autocad for somebody else you can try onshape, it's browser based so works well on all platforms.
I have regrettably moved to Onshape as well. Closest to fusion and free as long as youโre just making things for your own use. OpenSCAD is powerful, but I canโt get past the learning curve. Wish I could use it though. One day, maybe.
I use OpenSCAD for some gears etc, but onshape for the rest. I used FreeCAD for work a few years ago as we were stuck on Linux, I can wield it well, but it's a bit clunky and would crash often on things like threads.
Onshape just works for the home hobbyist. I wish FreeCAD was a bit better, but I understand it's a lot of work, just the creature comforts of fusion and onshape are hard to give back up.
I started with blender and I agree: It's not made for technical modelling. There is a custom blender version with common CAD features, but I've been put off by the - typical for Blender - steep lerning curve.
Long story short: You can't go wrong with FreeCAD.
freecad IS the tool for you. the learning curve may seem steep at first, but it's really not. after you spend some time with it, things start to click. i love it.
there's this repo and it still seems to be maintained. I was following this project when it first started and tried it for a while it seems pretty solid.
