I use FreeCAD and it's pretty good. But I think it's impossible to learn by trial and error.

MangoJelly has done an amazing job in churning out high quality tutorials for FreeCAD: https://www.youtube.com/watch?v=t_yh_S31R9g&list=PLWuyJLVUNt...

(this is just one playlist, there's a lot more on his channel).

Productive FreeCAD user chiming in here. I understand the frustration. It has a moderate learning curve, but the editing model forms an intuitive picture once you learn the basics and start using it.

Also second the MangoJelly tutorials. You will have a much better time if you walk through a few lessons first as opposed to just winging it and expecting to understand how everything works immediately.
