I'm curious why I don't hear more about mattercad here or elsewhere? It's free (not FOSS), and for me really fills the gap between tinkercad and most professional cad software. I often see questions about people wanting to move beyond tinkercad but being intimidated by the learning curve and the fairly large jump between it and higher powered software. Mattercad fits so nicely in this space. Yes it's a bit slow once shapes get more complex, and it has some frustrating bugs that I don't think will ever be fixed, but it's both powerful and simple. I'm curious if there are places people think it falls short or if you think I'm wrong and there is a better intermediate software package I should be considering?
