ARCC                                                                Menu: DRAW
==============================================================================
Creates an arc given the center point, starting point, and arc angle.

        1. * (POINT) center of arc
        2. * (POINT) starting point of arc
        3. * (NUM) arc angle (1-360)

Description:
This command creates an arc (wire entity) given the center point, the starting
point, and the arc angle. Pick the center point and the starting point.
Specify the arc angle (0-360). The angle is measured counterclockwise in
degrees from the imaginary radial that connects the center of the circle
(point 1) and its starting point (point2).
This command operates on any one of the three axial planes while in any
orthogonal view. If you attempt to execute this command while in axonometric
view the system will prompt you:
! <ENTER> invalid view, change to orthogonal !
You may create additional arcs until you enter another command. The last angle
value entered is returned when you create additional arcs.
Example:           \arcc 4 4 0 8 4 0 130
Result:            An arc with its center at 4 4 0, starting point at 8 4 0,
                   and a 130 angle counterclockwise is created.
