SketchUp also has two specialized zoom tools, Zoom Extents ( ) and Zoom Window ( ), which you learn about later in this section. As you draw a 3D model, zooming in can help you align edges and faces more precisely, whereas zooming out enables you to see your overall model or re-orient yourself so you can find a different part of your model to work on. In SketchUp, as in many other programs, you can zoom in for an extreme close up, or zoom out to see the bigger picture.

In SketchUp, choosing this view aligns your perspective so that the view has two vanishing points. Two-Point Perspective: Illustrators often use two-point perspective to draw 3D buildings and concept art.Perspective: In this view, lines vanish to a horizon, so certain items appear closer while other items appear to be far away.When you print in this view, line length has a scale (for example 4’ in SketchUp = 1" on paper). This view is also known as an orthographic view. Parallel Projection: In this view, lines appear parallel in both 3D and 2D space.

SketchUp’s Camera menu also has three perspective options, shown in the following figure, that change how you view your model: As you switch and modify your view, it’s as though you’re looking through a camera. Tip: When you use the standard views or the more advanced features of the navigation tools, remember that SketchUp uses the concept of a camera to represent your view.
