摘　　要：研究参数化方法中经常遇到的多解问题。首次提出了约束元和约束组的概念，从拓扑及空间关系的角度研究了解的标识方法和约束组求解的几何算法。该算法具有几何语义直接、精确度高、计算量小等优点。This paper discusses the multiple solutions problem which is encountered very often in parametric design.The definitions of constraint primitive and constraint group are given. An geometric algorithm for constraint group solving is presented. This algorithm is semantically more robust and computationally less expensive and more accurate.
