IN THIS CHAPTER

Understanding edges and faces

Representing three dimensions on a two-dimensional screen

Inferencing like a pro

Warming up with SketchUp

Lining up entities with guides

Adding color and texture to your work

When you were learning how to drive a car, you probably didn’t just get behind the wheel, step on the gas, and figure it out as you went along. (If you did, you probably have bigger things to worry about than getting started with SketchUp.) The point is, knowing some basic concepts can make your first few hours with SketchUp much more productive and fun.

So here’s the deal: This chapter has three main parts:

 The first part talks about edges and faces — the basic stuff that SketchUp models are made of.

 The second part explains how SketchUp enables you to model in 3D (three dimensions) on a 2D (flat) surface — namely, your computer screen. Understanding how SketchUp represents depth is everything when making models. If you’ve never used 3D modeling software before, pay close attention to the middle part of this chapter.

 The final part of this chapter is about the things you need to do all the time — things like navigating around your model, drawing lines, selecting things, and working with accurate measurements.
