,`XCENTER`

`YCENTER`

Working plane X and Y coordinates of the center of the circle or cylinder.

,`RAD1`

`RAD2`

Inner and outer radii (either order) of the circle or cylinder. A value of zero or blank for either

or`RAD1`

, or the same value for both`RAD2`

and`RAD1`

, defines a solid circle or cylinder.`RAD2`

,`THETA1`

`THETA2`

Starting and ending angles (either order) of the circle or faces of the cylinder. Used for creating a partial annulus or partial cylinder. The sector begins at the algebraically smaller angle, extends in a positive angular direction, and ends at the larger angle. The starting angle defaults to 0° and the ending angle defaults to 360°. See the

*Modeling and Meshing Guide*for an illustration.`DEPTH`

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

= 0 (default), a circular area is created on the working plane.`DEPTH`

Defines a circular area anywhere on the working plane or a cylindrical
volume with one face anywhere on the working plane. For a solid cylinder
of 360°, the top and bottom faces will be circular (each area defined
with four lines) and they will be connected with two surface areas (each spanning
180°). See the **CYL5**, **PCIRC**, and **CYLIND** commands
for alternate ways to create circles and cylinders.

When working with a model imported from an IGES file (DEFAULT import
option), you must provide a value for * DEPTH* or
the command will be ignored.
