I've bought several books from the "Dummies" series, and occasionally they leave a bit to be desired. This one really delivers.In just one weekend, with the help of this book and author Aidan Chopra's excellent companion videos on YouTube, I went from complete Sketchup beginner to actually producing usable construction plans for a small shed.Some teachers can take up a lot of your time without managing to get any practical information into your head. Aidan's got a knack for knowing and giving you what you need to know to get actually up and running with Google Sketchup.Five stars!
