> For those interested in open source 3D CAD applications, there's a really interesting application called SolveSpace which is a very, very fast and low resource 3D parametric CAD application. Yeah, it's cool project, and I'm one of contributors to SolveSpace development ;-) (mostly, tester and idea generator). SolveSpace not only 3D CAD - it is 2D/3D CAD and CAE too. I like to make stress tests for SolveSpace and already know many tricks, so if need some help with SolveSpace - ask me! (I often answer on SolveSpace Forum too). One of most active users of SolveSpace is Eric Buijs[0], that has many videos on his YouTube channel[1] about SolveSpace usage for solving tasks from different CAD challenges and competitions[2], such as "/r/CAD/ Challenge" (I has own archive[3] of those tasks), etc. > It's really useful, really fast Agree, it useful for daily work & small 3D printing tasks. But sadly it's not very useful for very big construction that consists of many sub-models yet... > and very stable Not so stable. Be careful - while SolveSpace often work like a charm, if you create redundant constrains it could freeze your PC very fast! Just need be careful with constrains and complex models design in SolveSpace.
