Create a pyramid that tapers to a point, or create a frustum of a pyramid, which
tapers to a planar face.

You can use the Mesh Primitive Options dialog box to set the default number of divisions
for a mesh pyramid.

After a mesh primitive is created, the current level of smoothness for the object
can be modified.

Mesh Pyramid Creation Options

The Pyramid option of the MESH command provides several methods for determining the
size and rotation of the mesh pyramids you create.

• Set the number of sides. Use the Sides option to set the number of sides for the mesh pyramid.
• Set the length of the edges. Use the Edges option to specify the dimension of the sides at the base.
• Create a frustum of a pyramid. Use the Top Radius option to create a frustum, which tapers to a planar face. The
  frustum face is parallel to, and has the same number of sides as, the base.
  
• Set the height and rotation of the pyramid. Use the Axis Endpoint option to specify the height and rotation of the pyramid. This
  endpoint is the top of the pyramid. The axis endpoint can be located anywhere in 3D
  space.
• Set the perimeter to be inscribed or circumscribed. Specify whether the pyramid base is drawn inside or outside of the radius.
