I've been treating FreeCAD like a rolling release by using the weekly Flatpack builds and it has been a pretty good experience so far. Based on a good model I was given as a starting point and a lot of Mango Jelly Solutions videos, I've developed a detailed model of the Virtual Pinball machine I'm building now. It has been huge in saving me from countless mistakes in the actual build.
