You can create a solid pyramid. You can define the number of sides for a pyramid from 3 to 32.
You can use the Axis Endpoint option of the PYRAMID command to specify the endpoint location of the pyramid axis. This endpoint is the top point of the pyramid or the center of the top face if the Top Radius option is used. The axis endpoint can be located anywhere in 3D space. The axis endpoint defines the length and orientation of the pyramid.
You can use the Top Radius option to create a pyramid frustum, which tapers to a planar face that has the same number of sides as the base.
