FreeCAD is ok, I use it for simple 3d printing designs, but you have to be very careful how you build the model as it likes to ruin dependencies if you change something in earlier sketch. 1.0 dev builds seem more user friendly.

Like some other good-bones free software, the UI is terrible. I challenge anyone who has prior CAD experience, but no FreeCAD experience, to install the software and design a simple bracket in under an hour.

I tried Fusion under Wine and it didn't really work. I haven't tried NX or Solidworks in the last few years.

I use Blender3D for everything I (as a total non-professional novice) would need 3D graphics-wise, but as I understand it, there are a few CAD options available on Linux, and several more that run fine in WINE for those who need more professional or proprietary options.

On Linux there's FreeCAD, SolveSpace, Dune3d and OpenSCAD in (subjective) decending order of capability. FreeCAD still suffers from the "topological naming problem", though there's a fork that helps with that and merging it upstream is an ongoing process.

I purchased Alibre Atom3d because it was the only non-subscription affordable package I could find, but it's quite disappointing and won't run in wine anyway due to the licensing rootkit it uses. So I end up using one of the above linux capable tools, depending on the needs of the model. Each one has its strengths and weaknesses and none is satisfying overall. I reach for OnShape for any design that is going to be open source, because it is a pleasure to use (even though it is web-based), but I don't make enough money from CAD to pay for a $1500 annual subscription.

Not CAD. None of the Linux options are on the level of SolidWorks etc.

Ah, right, CAD is still stubbornly there.

OnShape works well enough for most hobbyist uses of CAD, and runs fine on Linux. It’s quite a bit better than 360 IMO.
