摘要
变量化设计的核心是约束的建立、求解、传递及变动性修改等问题。本文提出了二维几何约束模型的建立及几何模型拓扑关系可迁移性的实现，并具有不依赖于作图过程的可变性修改的特点。
The keys involved with variational design are the establishment, solution, transmission, and the variational modification of constraints. This paper presents a method to establish a 2-D geometrically constrained model, and to realize the modification of topologic relation of geometric models. The method also has the unique feature of implementing the modification without having to rely on the process of drawing.
