McNeil, the company that produces Rhino, produce a level 1 and level 2 course for beginners and intermediate students, respectively. This book essentially covers everything that both of those original courses cover, in addition to most of the content from the instruction manual that comes with Rhino, all with (for the most part) significantly better designed examples. The author even goes into great depth as to how to use every last sub-command.
The problem is, right from the very first exercise, the author has written this book under the assumption readers have been using Rhino (or another kind of product design CAD) for at least 6 months. If I tried to use the book's first two exercises on my beginner Rhino students, they would be traumatized!
As far as the organization goes, this book feels as if the author is trying to teach you the Level 2 Rhino course first, with elements of Level 1 thrown in along the way. While he does use some fantastic abstract examples of every single process, the practical applications don't appear nearly as often as they should.
All in all, I would definitely recommend this book to anyone who has already taken BOTH of the Level 1 and 2 standard McNeil courses. For those who know the interface enough to fearlessly experiment, it will help provide some valuable additional insight into all the existing commands they know. For anyone else, you're better off learning the basics elsewhere.
