I care a lot about reliability! In fact, FreeCAD's incessant crashing (and the fact that it corrupted the savefile when doing that) was the single biggest reason I put so much time into improving SolveSpace, although working assembly support is a close second.

Even in case that SolveSpace does crash, it has an autosave facility (with a five minute interval by default), and so you should never lose more than five minutes of work.

You should also use the 2.x branch and not the released version 2.1, as the branch has some important bugfixes. I will release 2.2 within a few of days though.

I can't believe I hadn't heard of it before. I just went through the tutorial and I'm duly impressed. I'll definitely try this for my next design. I couldn't find a way to donate, but I'd gladly send an appreciation to the people working on this.
