You will see that there are 3 SketchUp Sections. Two of them are single project based and the other consists of building small miscellaneous objects in each lesson. You may choose to start on any of these sections. Each section provides a sufficient introduction to the basic tools and features in SketchUp. I created different versions for two reasons:

1. People learn things more effectively in different ways.
2. If you need to go over the concepts more than once you'll be able to without rewatching or building the same thing again. In a word: Variety.

Once you finish a section you'll have sufficient skills and knowledge to build almost anything in SketchUp.

Have fun and build things. -Jake
