#FreeCAD (https://www.freecad.org/features.php?lang=en) is good but missing enough features to make me truly miss #SolidWorks
If pirating SolidWorks or using FreeCAD are my two options I'm actually not sure what I'd pick.
Honestly? If there was a #CAD3d option with a reasonable subscription ($50-200/year) that didn't make me relearn my workflow I'd definitely pay for that.
Onshape is online only and makes all your designs public unless you pay them $1500 a year, which.... nah. Hell nah.
