DESCRIPTION

rdr is the relative version of draw.  It connects the current graphics position and a point, at the specified distance, with a line segment using the current linestyle, linewidth, color (if in depth-cue mode, the depth-cued color is used), and writemask.  The system updates the current graphics position to the new point. 

Do not place routines that invalidate the current graphics position within sequences of relative moves and draws.
