R&D Of Individualized GCAD Based On Parameters

Garment Computer Aided Design (short for GCAD), which applies the theories and technologies of the CAD area into various sections like garment design, manufacture, management and operation. So it intensively improves efficiency and quality of garment productions.Facing diversiform media and developing society, garment industry has a new requirement of the GCAD which can provide garment consumers for individualized services. Traditional garment industry's garment productions, which are of few patterns and models, can not meet with the requirement of individualized garments. With strong requirement of individualized garments, people want not only made to measure dresses, but also individuation of pattern, picture and material of the garment. The individualized services of GCAD have become an inevitable trend.Meeting with these requirements, this thesis makes a new resolution: designing a individualized GCAD system which automatically draws garment molds which are based on body parameters. According to the requirements of customers, this GCAD can make a free combination of pattern, picture and material of the garment. In this way, it not only implements made-to-measure, but farther meets with the psychology that people really want to design a dress by themselves. In this new method of singly measuring, singly reducing, singly designing and singly printing, this GCAD fully meets with the individualized requirement of garment market.This paper introduces the individualized design of the GCAD system, the theories and steps of garments configuration design, as well as principles of parameterized design. It emphasizes on setting up the parameterized design configuration, and a unified database which is served for the system itself. The system simulates the prototype method to design a pattern, abstracts the coordinate expressions of points on the pattern to a uniform formula. The parameter design configuration implements a dynamic driving between thepoints, lines and pieces of the pattern which is based on the body parameters. The innovations of this paper are as follows: the parameter design is based on the parameters provided by the consumers themselves;therefore, it can design a new pattern at a time. It solves the problem of made-to-measure of dresses, freely combination of style, material and picture of the dress, as well as individuation of the dress which is furthermore implemented by printing directly on the clean white cloth.
