A side benefit to using AutoCAD has to be the abundance of third-party software and support magazines, books, and bulletin boards .
I would like to recommend one of the best of these “ a monthly magazine called CADENCE: The World's Largest Independent CAD Magazine . CADENCE sports some of the finest technical writers in the field today (including the ever popular writer and speech- ifier, Lynn Allen).
I'm not affiliated with the magazine (indeed, I've never published with it but am open to requests “ how 'bout it, Editors?) but I try to recommend it to my more serious students. Pick up a copy at your local newsstand or magazine rack.
