| Abstract: | 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. |
