ABSTRACT:
A sizing processing system according to the present invention generates an offset figure based on an offset point set obtained by offsetting the respective sides of a source figure by a distance equal to a prescribed sizing amount. When an inside-out side is detected on the offset figure, two sides of the source figure that intersect at a vertex thereof associated with the detected inside-out side are translated by a distance equal to the prescribed sizing amount, and the respective end points of the thus translated sides corresponding to that vertex are taken as offset points. Then, the offset points are added to the offset point set to generate an offset figure that does not entail the generation of an inside-out side. This can also address the problem of an inside-out side that occurs when an edge cut is inserted in the offset figure.
