Abstract:
1. A method for symmetrically aligning a pattern piece relative to at least one layer of sheet-type work material defining a variable repeat pattern, the method comprising the steps of: providing at least one layer of work material defining a variable repeat pattern; identifying an initial position of the location of said pattern piece relative to said work material; identifying the location of a first reference point corresponding to a first portion of said pattern piece and the location of a second reference point corresponding to a second portion of said pattern piece; capturing first and second images of areal portions of said work material adjacent to and including said first and second reference points respectively; displaying at least a portion of said first and second images of said work material adjacent one another; moving said pattern defined by said work material in one of said first and second images relative to the pattern defined by said work material in the other of said first and second images an adjustment distance, such that the pattern defined by said work material in said first image is substantially aligned with the pattern defined by said work material in said second image; adjusting the position of said pattern piece relative to said work material proportionally to said adjustment distance so that said first and second portions of said pattern piece are located symmetrically with respect to said pattern defined by said work material.
