摘要
参数化设计方法是当今计算机辅助设计领域的一个热点课题，交互式三维参数化造型可以在原有模型的基础上，快速而方便地生成新的设计方案，大大提高了设计效率。本文所讨论的是通过引入特征和约束关系，利用现有的实体几何造型系统来实现交互式的三维参数化造型的方法。
Parametric design show enormous superiority in the respect of medifying product medels, and now it becomes a hot study of CAD field. The paper presents a method of realizing 3 - D parametric medeling based on solid goometry medeling system, which recommends feature, and establish constrains among feature entities in order to cause chain reaction of constrains. Thus it raises greatly efficiency of designing preducts.
