This is a book that you would get for free in your Autodesk package. Very dry run down tutorials. It took me an hour to go through 100 pgs. and get 2 usefull things out of it (1 per 50 pgs. to help you with the math). It probably took even less time to write it. (Sorry if I offended Travis and Neil but take pride in your creations, step back and see if you can actually follow and like what you did).But anyways, book is going back, don't recomend it, I only gave it one extra star just to be nice.
