Perspective View

Unlike the Plan view, the Perspective view is entirely 3D with realistic lighting and shadows. You can view your landscape design from any angle in this view. Some objects, such as doors and windows, are best edited in the Perspective view because there you can view the objects at eye level. The Perspective view is also especially useful for raising or lowering objects, modifying the terrain and grading, or changing the materials of an object.
