I just wish there was an actually free version of what Fusion360 offers. Even if it wasn’t nearly as good, like even half as good, it would be sufficient for hobby work. It’s just that to do anything remotely fancy there is simply no alternative. FreeCAD is just not even in the same league, sadly enough. The difference is so high that it’s not even worthwhile to discuss them together
I think the governance of the freecad project has recently changed so I'm cautiously hopeful that it will finally start seeing some project management and UX love.
I think the unfortunate part about FreeCAD that is not really solvable is being based on OpenCASCADE. There are apparently some fundamental flaws in that kernel that make it leagues behind Parasolid and ACIS
3D printing is in the same boat. It seems the whole CAD industry just wants to shoot itself in the foot and push people towards open source tools.
When I was into 3D printing 5 years ago I learnt Fusion 360 and it seemed like one of the better free-for-hobbyist tools, but even then it was buggy on Windows (didn't properly support 4K) and features were slowly being moved behind the premium paywall. SketchUp is also quite popular, but people stick to the old version that can be run offline, as the newer web based versions don't have the same features.
