Contrary to popular belief, modeling in SketchUp doesn’t involve drawing in perspective and letting the software figure out what you mean. This turns out to be a very good thing, for two reasons:

 Computers aren’t very good at figuring out what you’re trying to do. This has probably happened to you: You’re working away at your computer, and the software you’re using tries to “help” by guessing what you’re doing. Sometimes it works, but most of the time it doesn’t. The word processing software we all use is a good example. Eventually, the computer’s bad guesswork gets really annoying. Even if SketchUp could interpret your perspective drawings, you’d probably spend more time correcting its mistakes than actually building something.

 Most people can’t draw in perspective anyway. Even if you’re one of the few folks who can, you know darn well that most people couldn’t draw an accurate 3D view of the inside of a room if their lives depended on it. Drawing just isn’t one of the things people are taught, unfortunately. So even if SketchUp did work by turning your 2D perspective drawings into 3D models (which it most certainly doesn’t), the vast majority of those who “can’t draw” couldn’t use it. And that would be a shame because building 3D models is a real kick.SketchUp defaults to displaying models in a perspective view because it’s commonly used for architectural designs. Real buildings are usually big enough that we can see the perspective effect. You can always switch to a parallel view (useful for 2D plans and other diagrams), which we cover in “Switching to a 2D view” in Chapter 4.
