Once upon a time, software for building three-dimensional (3D) models of thing like buildings, cars, and other stuff was hard to use. I mean really hard — people went to school for years to learn it. And if that wasn't bad enough, 3D modeling software was expensive. It was so expensive that the only people who used it were professionals and software pirates (people who stole it, basically). Then along came SketchUp.

Operating under the assumption that lots of people might want — and need — to make 3D models, the folks who invented SketchUp decided to design a program that worked more intuitively. Instead of making you think about 3D models as complex mathematical constructs (the way computers think), they created an interface that lets you build models using elements you're already familiar with: lines and shapes.

So do you need to know how to draw to use SketchUp? In the latest version of the software, not really. Traditional drawing is about translating what you see onto a flat piece of paper: going from 3D to 2D, which is hard to do for most people. In SketchUp, you're always in 3D, so no translation is involved — you just build, and SketchUp takes care of stuff like perspective and shading for you.

This first chapter is about putting SketchUp in context: why Google offers ...
