Let's take a look at our plan in 3D and see how it looks so far. For more information about creating 3D views, see "Render Views".
To create a doll house view

(should be selected by default) and click and drag the mouse on screen to change the camera perspective. You can press the I (in) and the O (out) keys on the keyboard to zoom in and out of the plan.
