Smar Tac & Workobject relationship? [ArcWelding PowerPac]

Hi friends....
         If we are working on a welding component of rectangular cube shape whose edges are perfectly along the "X" & "Y" Axes of the robot base frame & we are using the Smar Tac feature for detecting the shift (2-5mm) of the welding component in parallel with "X" OR "Y" Planes, then is it necessary to do the teaching of all the robtargets by using the optional argument of the workobject ????
