Working with Components in Google SketchUp 8
In Google SketchUp, components are groupings of geometry (edges and faces) that make working in SketchUp faster, easier, and more fun. In a lot of ways, components are really just fancy groups — they do a lot of the same things. After you can make components, you’re on your way to SketchUp stardom.
A few attributes make components so great:
Everything that’s true about groups is true about components.
Components update automatically.
Using components can help you keep track of quantities. You can use the Components dialog box to count, select, substitute, and otherwise manage all the component instances in your model.
You can make a component cut an opening automatically. You can set up SketchUp components to cut their own openings in faces. These openings are even temporary; when you delete the component, the hole disappears.
Components that are set up to automatically cut openings can do so only through a single face. Even if your wall is two faces thick, your components will cut through only one of them.
You can use your components in other models. If you have a group of parts or other things you always use, making your own component collection can save you a lot of time and effort.
Components are great for making symmetrical models.
You can bring any SketchUp model on your computer into your current file as a component. That’s because components are really just SketchUp files embedded in other SketchUp files. When you create a component in your model, you’re effectively creating a new, nested SketchUp file.
