==============================================================================
Creates an arc given three points along its perimeter.

        1. * (POINT) first point of arc
        2. * (POINT) second point of arc
        3. * (POINT) third point of arc

Description:
This command creates a (wire entity) arc, given three points. Pick three
points in succession: the first point is the starting point of the arc, the
second is a point anywhere on the arc, and the third is the end point. An arc
passing through the three points will then be created.
NOTE:The three points define the plane on which the arc is created; they must
not lie on a straight line. To create a circle, use the \lcirc or \arcc
command, or use \ar3p twice.
You may create additional arcs until you select another command.

        Example: \ar3p 0 0 0 4 0 0 4 4 0

Result: An arc is created starting at 0 0 0 passing through 4 0 0 and ending
at 4 4 0.
