>Trying to learn 3d first will melt your brain.
Nonsense. Old thinking carried over from the drawing board days. I started out making 3D parts. Real 3D parts - out on the shop floor. Someone figured out a long time ago the world is not flat. It is far more natural to design representative of the real world and now we have software that largely automates the conversion to practical paper communication medium.
I keep walking into companies to do consulting and find that they created the real world parts FIRST and THEN tried to figure out how to document.
