Abstract: At least one dividing line formed of a straight line is set in a hole forming region surrounded by a hole processing line. It is determined whether or not a smaller one of connection angles at a first connecting point at which the dividing line is connected to a hole processing line is smaller than a predetermined angle. When the connection angle is smaller than the predetermined angle, a line segment between an auxiliary line and the hole processing line is replaced with corrected dividing line. A corrected connection angle at a second connecting point at which the corrected dividing line is connected to the hole processing line is set so as to be larger than a connection angle before correction.
