**Creates a regular polygonal area or prism volume anywhere on the
working plane. **

`NSIDES`

The number of sides in the polygon or prism face. Must be
greater than 2.

`XCENTER`

, `YCENTER`

Working plane X and Y coordinates of the center of the polygon
or prism face.

`RADIUS`

Distance (major radius) from the center to a vertex of the
polygon or prism face (where the first keypoint is defined).

`THETA`

Angle (in degrees) from the working plane X-axis to the vertex
of the polygon or prism face where the first keypoint is defined. Used to
orient the polygon or prism face. Defaults to zero.

`DEPTH`

The perpendicular distance (either positive or negative based
on the working plane Z direction) from the working plane representing the
depth of the prism. If `DEPTH`

= 0 (default), a
polygonal area is created on the working plane.

## Notes

Defines a regular polygonal area anywhere on the working plane or prism
volume with one face anywhere on the working plane. The top and bottom faces
of the prism are polygonal areas. See the **RPOLY**, **POLY**, **RPRISM**,
and **PRISM** commands for other ways to create polygons and
prisms.
