Query: it should be simple

While McFarlane deals with the latest version of AutoCAD, it is in a deliberately restrained fashion. He offers to teach you two dimensional drawing with what has been for years a fully three dimensional package. He asserts that in the headlong drive into three dimensional design, something might have been lost in the education of engineers. Namely a firm grounding in the ability to do two dimensional layout.I cannot say that I fully agree that this has been a deficiency in recent education. But perhaps for some students it has. If so, you may want to turn to his book to cover this deficit. The book should not be hard, one hopes. 2d stuff is much simpler. And you are only touching a rather small subset of AutoCAD's functions.
