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 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, i.e., 4 for 360°). Number of keypoints
generated is NSEG
for 360° or NSEG
+
1 for less than 360°.
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.
