Abstract Shoe last lS the solid form around which 3 shoe lS molded．Development Of CAD system for shoe last is the key solution to improve shoe last industry．This paper focuses on the key modeling technologies of shoe last CAD system．Firstly，based on Object-Oriented technology，the design model of shoe last is constructed．Secondly，the point based geometric model of shoe last is defined，the surface point data set after regular processing represent the design geometric and the surface model generated from the data set is used as result displaying and subsequent applications such as NC programming． Finally，the system model that denotes the framework of the whole CAD system is presented．W ith these three models，3 practical shoe last CAD system is realized successfully．

鞋楦CAD系统建模研究
鞋楦是制鞋的模具，开发鞋楦CAD系统对于提高鞋楦的设计制造水平具有重要意义．研究了鞋楦CAD系统建模中的关键技术．首先根据鞋楦设计特点，应用面向对象技术，构建了鞋楦设计模型；然后提出了一种实用的鞋楦几何模型处理技术，由经过规则化处理的表面数据点集定义鞋楦几何模型，经进一步造型处理获得的鞋楦曲面模型用于设计结果的显示和数控编程等后续应用；最后给出了系统开发的总体模型．应用这些建模方法，成功开发了鞋楦CAD系统．
