**Defines a circular arc.**

`P1`

Keypoint at one end of circular arc line. If `P1`

=
P, graphical picking is enabled and all remaining command fields are ignored
(valid only in the GUI).

`P2`

Keypoint at other end of circular arc line.

`PC`

Keypoint defining plane of arc and center of curvature side
(with positive radius). Must not lie along the straight line from `P1`

to `P2`

.
`PC`

need not be at the center of curvature.

`RAD`

Radius of curvature of the arc. If negative, assume center
of curvature side is opposite to that defined by `PC`

.
If `RAD`

is blank, `RAD`

will
be calculated from a curve fit through `P1`

, `PC`

,
and `P2`

.

## Notes

Defines a circular arc line from `P1`

to `P2`

.
The line shape is generated as circular, regardless of the active coordinate
system. The line shape is invariant with coordinate system after it is generated.

When dealing with a large radius arc (1e3), or if the location of the
arc you create is far away from the origin of your coordinate system, anomalies
may occur. You can prevent this by creating the arc at a smaller scale, and
then scaling the model back to full size (**LSSCALE**).
