Abstract This paper adopted hypergraph to represent const raint-graph, and geometric reasoning was used to solve constraints, meanwhile, the computing of geometricentities was based on feature points.This method can realize parametric design with multi-constraint driven ( such as area constraint) . It is
proved to be efficient and has been used as a tool for parametric design in AutoCAD.

AutoCAD 中基于超图约束驱动参数化设计的实现
使用超图表示约束模型，采用基于超图约束驱动的几何推理约束满足法进行参数化设计，几何实体的计算基于特征点。作者结合在ＡｕｔｏＣＡＤ上开发参数化设计模块的实践，得出该方法能处理多实体约束关系（如面积约束），提高求解效率，降低时间复杂度。
