I have experience with SketchUp which I’d imagine is like TinkerCAD. It was very simple and I was able to learn it very quickly. I think it should be enough to give me a good sense of how tools like these work.

While going through tutorials I definitely found that issue you were talking about where a lot of things are either renamed, moved or absent and I had to go puzzle out the “new way” to do the thing in the tutorial.
