Development of three‐dimensional apparel CAD system

A fast response three dimensional garment drape shape prediction system has been developed. A human body model generator has been established for the garment draping on it. For the mass production of different size of garments for the various sized body models, the cross‐sectional value from the anthropometric data was used as the standard for the size accommodation to make a resizable human body model. To construct the cloth drape shape prediction system, the finite element analysis method has been utilized. The designed garment pieces were divided into fine quadrilateral elements using a specially coded mesh generating program, then some appropriate sewing conditions were assigned to transform two dimensional patterns into three dimensional shapes. The final drape shape of the garment was determined from the solutions of the contact condition with human body, deformations, and the weights of the elements constituting the garment pieces, as well as the surface texture of the cloth.
