I don't know if someone would like to know how to do plans only with CAD and not know how to do them by hand as well. I am not in the aerospace industry so I wouldn't know, but in the civil engineering department we were thought first by hand and then in CAD. In fact, all our work is based on printed plans (from CAD of course).
I suggest you get involved and train by hand as well as with computer software. It just makes you more versatile. Oh, and someone mentioned something about the work of a draftsman standing out from the rest. That may be true, but in reality draftsmen are always paid below an engineer for doing the same work in AutoCAD.
