服装结构设计CAD系统开发

THE DEVELOPMENT OF APPAREL STRUCTURE CAD SYSTEM

本文对计算机辅助服装结构设计系统的设计思想与实现方法进行了探讨.提出将结构设计过程分作结构线设计和外形线设计两步完成,用导出关键参量计算模型的方法解决结构线设计中的经验估值问题;用图形变换的方法解决外形线设计中的"临摹"手法,从而较好地处理了设计师进行结构设计时所表现出的"活"的方面.以此为基础,在IBM PC/XT机上研制初步的服装结构设计系统.

This paper discusses the design ideas and the implementation of computer aided apparel structure design system, presents that the structural design can be achieved in two steps, the structural line design and the outerline design. It derives some formulae to calculate the key parameters in the structural design which were valued with experience before, solves the outline copy problem using graphic transformation, therefore, it processes suitablely the flexiable asperts in designer's structural design. Finally, this paper introduces a software system developed by us on the computer IBM PC/XT and the graphic data structure used in this system.
