【摘要】 本文提出了一种基于变分几何的参数化设计绘图方法。该方法根据对实际工程图纸的分析，将图纸信息分解为结构图元与轮廓图元两大部分，并对传统变分几何的设计方法作了大量的改进，从而提高了设计绘图效率。本文主要介绍了该方法的基本设计思想和数据模型更多还原

【Abstract】 In this paper a parametric design method based on variational geometry is presented. It separates the drawing information into two parts:the Structural Elements and the Contour Elements. With the development of variational geometric solving method and the constraint propagate algorithms, the drafting performance are improved greatly. This paper presents the general principle and data model of this approach.更多还原
