The problem with (3D) CAD I've heard is that the Open CASCADE CAD kernel is a huge mess. So as much as they update and fix FreeCAD (and they've made a lot of good progress, but it's still very rough around the edges) they're always going to be hampered by that. And making a new CAD kernel is a massive undertaking.
Question for someone who is very far away from this kind of development - why does CAD software need a kernel that’s wholly separate from the UI? Why aren’t they the same thing? I just don’t understand the abstraction that necessitates writing the software this way.
