This option allows you to define and save new construction planes. A construction plane, represented by a gnomon, defines a coordinate system upon which entities are created and manipulated. Use a construction plane to create entities in a different plane from the currently displayed plane. Display of the CPlane gnomon is controlled through the Tools>Options>Display page.

The number of the active CPlane is displayed in the Status Bar (double click to open Cplane list)  located on the bottom right of the application. If the current CPlane is unsaved, it will have the number 0.

Changing the Construction Plane

There are eight standard CPlanes that are equivalent to the standard views listed under Display View. These Standard CPlanes cannot be modified, renamed, or deleted.
