Command				defaults (Range)	Description
------------------------------	-----------------------	--------------------------------------------------------
AA x, y, a [,b];					Arc Absolute): Angle is a floating point # (requires non integer value) Draws an arc with the center at (X,Y) and a positive angle creates a counter-clockwise arc. If the chord angle is specified, this will be the number of degrees used for stepping around the arc. If no value is given then a default value of five degrees is used.
AR Dx, Dy, a [, b];					Arc Relative): Angle is a floating point # (requires non integer value)Draws an arc with the center at offset (X,Y) . A positive angle creates a counter-clockwise arc. If the chord angle is specified, this will be the number of degrees used for stepping around the arc. If no value is given then a default value of five degrees is used.
