Okay, my first experience using FreeCAD, I’ll just run it on Raspberry Pi 4 like I do any computer, right? Wrong! I install it, it starts up okay, but then when I am about to open any 3D model, it crashes! Why? Well, apparently it had a long history of not working on any Raspberry Pi version, but never fear, there is now a way to make it work on Raspberry Pi 4. You just have to… compile the latest version of the package yourself.
