摘要： 从特征造型软件开发的角度对参数化特征造型的一些关键技术进行了研究,并在几何平台上开发了一个参数化特征造型原型系ACIS统。讨论了的关键技术:基于标识的特征表示模型、标识子系统、统一二、三维约束的基于子图的草图设计及约束求解方法、基于GDSGDS约束依赖图的特征编辑算法等。

Abstract: This paper discusses the method and thchnique used in parameter feature-based modeling system GDS developed on ACIS platform. An identifying system is presented, based on which a product presenting model is put forward.A childgraph-based sequence approacesh to parametric design is presented.Feature editing algorithm is designed.
