PRRC PRRC - in Path, at Relative position, draw aRC Format PRRC x-coordinate, y-coordinate, radius, start-angle, end-angle; Parameters x-coordinate/ y-coordinate: coordinates as measured from the current cursor position radius: radius of arc start-angle: starting angle, measured counterclockwise from the positive x axis end-angle: ending angle, measured counterclockwise from the positive x axis Function The PRRC command first of all adds a line extending from the current position to the beginning of the arc which is centered at the coordinates relative to the current position, then adds the line and the arc to the current path. Coordinates and radius are measured in the units designated by the UNIT command; the starting and ending angles are measured counterclockwise from the positive x axis. For example, the following example draws an arc extending over the center of the arc: PRRC 1, 1, 0, 180; Whereas, the following command, having the reversed starting and ending angles, draws the arc under the center of the arc: 211
