This book is not a series of lessons, but a reference book that you can use as you work. It is a reference book both for beginners and for those who have struggled for some time to learn Blender. If you are completely new to Blender, at some point you will sit down to begin your first Blender session; you will begin to build your first model. Now imagine that, to help you any time you need assistance, there is a Blender pro standing next to you. Imagine that you tell him what you want to do, and he tells you exactly how to do it, step by step. That is how this book teaches. There are only a few, very short, lessons that you ought to commit to memory–the rest is on-the-job training. You will not need to do exercises; rather, you will be able to work on your own project from the very start. This book is not about studying; it is about doing.
