Use layers to organize related shapes on the Drawing Page. You can assign shapes to different layers, to selectively view, print, color, and lock different categories of shapes, as well as control whether you can snap to or glue to shapes on a layer.
Handset Designer imports the layers in an AutoCAD drawing. The Layer Properties dialog enables you to work with these layers. After you finish overlaying Walls, you can choose to hide the layers and set other layer properties. You can add, remove or rename a layer and you can also apply layers to drawings that you create with Handset Designer.
