I was looking for along time for a book of this kind, but lalely i found this book in my friends library. i never thought that there will be a good book that will be able to describe so well the procedures and the steps for learning and understanding the logical order of Mechanical Desktop 4. in the book i found explenations and step by step notes about usage of Mechanical Desktop 4. this book has verry helpful index and is verry good as a hand book. thanks alot to Daniel T. Banach for opening a whole world infront of me.
