it made no sense to me
That’s all CAD software. You can’t just jump in and intuitively learn it by just doing it. It’s like trying to learn a programming language. You need a solid tutorial to explain the basics, at a minimum. Even with something simple like TinkerCAD.
FreeCAD was probably the worst choice. Give TinkerCAD a try. I know the FOSS community will hate me for saying this, but I like Autodesk Fusion for a full featured CAD package. It has a very steep learning curve, like all CAD software, and you need to watch some videos first. You will make a ton of mistakes and do even simple things wrong at first, but once you get going, it’s great to use.
That’s not googling, that’s ducking. Besides everyone knows you should get that kind of answer from ChatGPT.
