AR, Arc Relative
This command draws an arc, using relative coordinates, which starts
at the current pen location and pivots around the specified center
point.

The AR command draws the arc starting at the current pen location
using the current pen up/down status, line type, and attributes. After
drawing the arc, the pen location remains at the end of the arc.
Note Do not use an adaptive line type when drawing arcs with small chord
angles. The printer attempts to draw the complete pattern in every
chord (there are 72 chords in a circle using the default chord angle).

— Specify the center of the arc relative to
the current location. (The center of the arc is the center of the
circle that would be drawn if the arc was 360 degrees.)
Coordinates are interpreted in current units: as user-units when
scaling is on; as plotter units when scaling is off. If current scaling
is not isotropic, the arc drawn is elliptical rather than circular.
