| 摘 要： | 介绍了一种参数化设计系统中约束的层次结构。该结构具有３层约束：工程约束、适配约束和几何约束。适配约束用于将工程约束转换为几何约束，从而实现工程约束对参数化几何图形变动的控制，而整个约束系统的求解也能够通过多个子系统的分别求解来完成。

| Abstract: | This paper presents a layered structure of constraints in parametric design system. T'he structure contains three layers : engineering constraints, adapting constraints and geometric constraints. Adapting constraints transform engineering constraints into geometric constraints, so that parametric modification of a product's shape can be driven by engineering constraints directly, and solution of total constraints can be accomplished by solving some subsystems. |
