Probably the best book on ADT I've come across if learning the program is what you really want to do, as opposed to the "reference" books that Autodesk usually dish out.
The book takes you step by step in a good tutorial fashion through constructing an entire model in the computer, and then generating your plans, sections and elevations from this one model.
After a breif introduction to showing what ADT can do, the speed at which you work can seem to get a little bogged down and some of the more important features could do with being better explained - and to some extent, it seems that to get the most from this book, you should give it a second read through.
To it's credit, the step-by-step nature is very easy to follow and at no time did I lose my way (an absolute first!!), but some of the background information on why you do this or that tends to be over-complicated and rather drawn out - an "Idiot's Guide" this certainly is not, and it's assumed that you are already reasonably proficient using plain AutoCAD.
Like any computer program, regular use is the key to learning, but this book is good at getting you up and running, and I'd strongly advise going over some of the sections again - they do become a lot clearer second time around.
I give this book an average rating - it has pro's and cons in equal measure, and to be honest the biggest problem for me was the American Imperial measurements that were used throughout. My advice is don't try to convert to metric as you go along, but just to stick with the feet and inches as you work through.
