without knowing the number of users you are issuing this manual to my first thought was, for a small office this would be good. something simple running though set up to ploting. i really liked the part about not copying an old project to start a new one....i hate those unused layer filters and such. something i would suggest is adding something about customization. the users limits. i noticed autocad 2005 LT is in the manual so maybe there arnt any lisp routins being used. but i would think it important that for standars reasons users should be using the same routines. just a thought. also, and this isnt really a 'manual' comment but a procedure comment. when we recieve electronic files its usually for an x-ref. so we zip them up and name them according to the date recieved. then we extract the drawings and clean them up for our own use. like killing the layer filters and things. basicly a purge. just to make them clean and small for our x-ref. this is just an idea. for some fields this wouldnt matter as much.
hope this helps. other than that, i liked the flow of the manual you have going.
