Generates circular arc lines.
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 andPCENT
= P, the radius is the distance fromPCENT
toPZERO
.PAXIS
Keypoint defining axis of circle (along with
PCENT
). IfPCENT
= P andPAXIS
is omitted, the axis is normal to the working plane.PZERO
Keypoint defining the plane normal to circle (along with
PCENT
andPAXIS
) and the zero degree location. Need not be in the plane of the circle. This value is not required ifPAXIS
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° orNSEG
+ 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.
