The only drafting experience I have is from high school and that was long enough ago that it was with pencils t-squares and the like. I spent yesterday watching Fusion 360 tutorials and did manage to finally make a drawing although it was probably luck. for everything other than my CNC router 2D would be sufficient. I am noticing most tutorials regardless of the program, tend to go to fast. They assume you know where all the features are located and which features you need. I wished there was a local school that taught it.
