I use FreeCAD and Assembly3 for everything and have for many years now. I sometimes use realthunder’s fork of FreeCAD but right now it’s quite a bit behind upstream and there are some cool new features in sketcher so I use upstream for those.
Some people get confused about workflow in FreeCAD because there are so many options and every youtube video has different opinions or tries to feature a particular workbench like curves or something. My opinion… Pretty much your workflow starting out should be to ignore everything else and use part design and sketches, it’s the simplest way:
enable autosave with a short interval, like 2min
Switch to part design workbench
create body
create sketches as the base of the features of your part attached to the xy, xz, yz planes, offset them to create a “wire frame” that resembles your project
a. Your sketches should be fully constrained
b. Your sketches should have as little geometry in them as possible, if you need more complex stuff make more sketches
c. Your sketches should have closed wires, you can’t pad something that doesn’t create a face.
use pad, pocket, revolution, loft, and hole operations on those sketches to form a 3d solid
if you need to create additional sketches which import geometry from the previous operations (using the external geometry tool), import SKETCH geometry from the previous ops, not edges of solids, whenever possible. Hide your solid, unhide your sketch, select that with the external geometry tool.
a. Use sketch on face sparingly.
Do fillets and chamfers last, if you need to change something, delete them and recreate them once you’ve made your changes.
To make multiple parts make multiple bodies with the same workflow as above.
Once you get pretty good at making static parts with constrained geometry, holes, threads (with the hole function), etc, which you can do with only the stuff above, then you can branch out into other workbenches like assemblies or curves, but all of those things build on the concepts above, so it’s easy to get overwhelmed if you try to do it all right from the start. Learning how to recover from a mistake is just part of CAD in general, though I admit that it’s a bit more effort to find what’s wrong in FC vs commercial platforms, but we aren’t here, on lemmy, in a linux community, to use commercial platforms.
AFAIK that’s pretty much the same workflow as F360 uses for single-solid parts though things have different names. pad=extrude for example.
It’s obviously far from perfect but in my opinion it’s the best solution that runs natively on Linux and is actually open source. Also assembly3 uses solvespace as it’s backend solver so if you make assemblies using that you are kindof using solvespace too.
Also, I hear/read a lot of complaining about instability but I’ve honestly never had a crash that wasn’t on an experimental branch like RT or the edge release of upstream. However step 0 above should help if you’re worried about that.
