Query: This book is a reference, not a tutorial

Some comments on this book are misleading.After seeing many five stars comments onthis book, I bought it as a tutorial.After reading this book and using thesoftware for several weeks, I had not learnedmuch. I decided to give up this book.My friend used this book for learningAutoCad, she also had to give up.Later I decided to buy another AutoCad book, called"AutoCad 2000 - One step at a time", tolearn AutoCad.
