PCENT

Keypoint defining the center of the circle (in the plane of the circle). If PCENT = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI).

RAD

Radius of the circle. If RAD is blank and PCENT = P, the radius is the distance from PCENT to PZERO.

PAXIS

Keypoint defining axis of circle (along with PCENT). If PCENT = P and PAXIS is omitted, the axis is normal to the working plane.

PZERO

Keypoint defining the plane normal to circle (along with PCENT and PAXIS) and the zero degree location. Need not be in the plane of the circle. This value is not required if PAXIS is defined along the Y axis (that is, a circle in the XZ plane).

ARC

Arc length (in degrees). Positive follows right-hand rule about PCENT-PAXIS vector. Defaults to 360°.

NSEG

Number of lines around circumference (defaults to minimum required for 90°-maximum arcs, that is, 4 for 360°). Number of keypoints generated is NSEG for 360° or NSEG + 1 for less than 360°.

Notes

Generates circular arc lines (and their corresponding keypoints). Keypoints are generated at regular angular locations (based on a maximum spacing of 90°). Arc lines are generated connecting the keypoints. Keypoint and line numbers are automatically assigned, beginning with the lowest available values (NUMSTR). Adjacent lines use a common keypoint. Line shapes are generated as arcs, regardless of the active coordinate system. Line shapes are invariant with coordinate system after they are generated.
