Parametric Characteristic Study On Sleeve Pattern Design

Garment Computer Aided Design System, since its birth, has brought an incomparable effect both on raising the modern management level of the enterprises, and promoting the modern progress walk of the whole industry. With the development of the new computer generation and artificial intelligence technique, the expert system, knowledge engineering will be applied into the CAD system, so developing the intelligent CAD system has become the inevitable development trend.Based on the current PDS development condition and the actual need of the companies, this paper focus on the parametric characteristic study on sleeve pattern design. This paper adopts the scientific research method, and carries on the research along such a way: question→model→method→program.This paper emphasizes on modular programming parametric modeling based on characteristics. It translates the parameter models into program language, and develops the automatic sleeve pattern design system. The main contributions consist of: First of all, analyzing the human body's dynamic and static state (especially the upper limbs), which providing scientific foundation for the sleeve pattern design, and studying the thought of parametric design theoretically, including the concept, technique character, method and so on, which establishing the foundation for modeling.Then, in the part of sleeve pattern design theory study, considering the related structural factors, obtaining the changeable range of each factor in theory.Thirdly, analyzing the pattern design method of suitable sleeve on the foundation of theory research, establishing the parameter models of the sleeve pattern, then inosculating the sleeve cap by AutoCAD based on the principle of NURBS.Finally, choosing layer structure as model frame, customizing and developing the automatic sleeve pattern design system based on AutoCAD. And establishing a database, with which querying and calling out the pattern according with the factors keyed in.The automatic garment pattern design technique accords with the development trend of current CAD. It not only improves the high-tech level and economic benefits of garment industry, but also solves such problems as training difficulty, bad technology stability and frequent technician flow.This study puts forward a scientific method for the technical study of automatic garment pattern design system. It has great significant and will be useful and helpful for further study in the future.
