Google SketchUp Cookbook

The Google SketchUp Cookbook is for intermediate and advanced users of Google SketchUp. It goes beyond the basics to explore the complex features and tools that design professionals use. You'll get numerous step-by-step tutorials for solving common (and not so common) design problems, with detailed color graphics to guide your way, and discussions that explain additional ways to complete a task. Cost: less than 50$ for the paper edition.
