At my rather beginner level, designing single parts for a 3D printer or laser engraver, it behaves almost exactly like most other parametric-history CAD apps in the broad concepts. The devil is just in the details, really. Shortcuts are different, terminology is different, Certain QoL and UI elements are either missing or somewhere else. The workbench model is not unique, but some of the kruft that has built up around FreeCAD’s benches and the defaults (better in recent versions if you look at the start screen) can make a new user “nope out” if they have other options. I guess assemblies in particular remain a fragmented area and lag behind the commercial packages, and I can say for certain that it still requires “good design practices” in a way that some of the commercial apps manage around, toponaming the biggest among them.

If all the negatives kill your workflow to the point that you want to pay for commercial software or live with the limitations (current and potential) of their free tiers, then that’s absolutely understandable. Commercially, it’s doubly so, and with addition of the “business reality” that there’s also no one to blame or sue if FreeCAD is not working for you. Hell, I don’t use it for all my stuff either, as I find no-history modeling still mostly works for what I’m doing and I have some free or cheap options in that space that are decent, but I can see the appeal as I’m starting to make things that could benefit from tweaks after the fact. What I get frustrated by is claims that FreeCAD “is no good” or “will never be useful”. I call BS. It’s already good and useful for many use cases, and anyway the number of free parametric CAD suites that do not restrict your use of your designs is exactly ONE. Otherwise, you’re looking at an absolute minimum of $300 a year to subscribe and hope that Shapr3D’s new history functionality doesn’t break, and that neither they nor Alibre gets gobbled up.
