Abstract: The current CAD software lacks of designing knowledge reuse, and most of them are based on WIMP interaction. This paper designs and implements a garment CAD system based on knowledge reuse, whose architecture includes knowledge recommendation module and knowledge editing module. In the knowledge recommendation phase, it proposes a real-time knowledge recommendation algorithm based on similarity calculation of pen sketch. In the knowledge editing phase, it provides a knowledge editing method based on pen gesture, and gives the application instance of the system. This system is used in a cashmere factory in Beijing, and the practice proves this system can improve human-computer interaction experience, and improve the design efficiency.

Key words: knowledge reuse, knowledge recommendation, CAD

摘要： 针对当前CAD软件对设计知识重用支持不足且大多基于WIMP交互方式等问题，设计并实现一个基于知识重用的服装工艺设计系统。该系统框架主要包括知识推荐和知识编辑2个模块。针对知识推荐和知识编辑，分别提出基于草图相似性的实时知识推荐算法和基于笔手势的知识编辑方法，给出系统的应用实例。该系统已应用于北京某羊绒企业的生产中，实践表明该系统能改善人机交互，提高设计效率。
