Product shape designing device

A computer program for designing a product shape that fits a human body, comprising:

• a first step of converting measurement data of a human body shape A, a human body shape B and a product shape C which fits the human body shape A into data expressing the human body shape A and the human body shape B with the same number of coordinate points on an identical geometric structure;
• and
• a second step of calculating, based on the data converted by the pre-processing unit representing the human body shape A, the human body shape B and the product shape C, a deformed grid G in which a deviation among individuals of the human body shape A and the human body shape B, and a deviation between a circumferential length of a cross-section H determined according to the product shape C and a target circumferential length of the cross-section are minimized at a time, and applying the deformed grid G thus calculated to the product shape C to thereby deform the product shape C, so as to output data of a new product shape F that fits the human body shape B.
