Читать книгу SketchUp For Dummies - Mark Harrison - Страница 36

In SketchUp, everything is made up of one of two kinds of elements: edges or faces. They’re the basic building blocks of every model you’ll ever make. It’s kind of like ancient times, when everything was made of just earth, air, fire, and water.

Collectively, the edges and faces in your model are geometry. Other modeling programs have other kinds of geometry, but SketchUp is pretty simple. That’s a good thing: You have less to keep track of.

The drawing on the left in Figure 3-1 is a basic cube drawn in SketchUp; it’s composed of 12 edges and 6 faces. The model on the right is a lot more complex, but the geometry’s the same; it’s all just edges and faces.
