| 摘 要： | 三维参数化特征建模是当今三维CAD的主流技术,而二维参数化草图技术是其重要基础。本文围绕二维参数化草图技术,系统地研究了如何向二维草图添加结构约束和尺寸约束,并在图的基础上,通过建立和搜索尺寸链和拓扑链进行尺寸驱动来实现参数化设计。在此基础上,采用面向对象编程技术,用C#语言在Win-dows2000平台上开发一个二维参数化草图设计原型系统。

| Abstract: | Three-dimensional parametric feature modeling is the main technology of today's three-dimensional CAD. The two-dimensional parametric sketch technology is the important foundation for three-dimensional parametric feature modeling. In this paper, the method of adding structural constraints and metric constraints is discussed. And based on the graph, the parametric design is realized by dimension-driven approach, which includes creation and search of dimension chain and topology chain. On the basis of the theory study above, a two-dimensional parametric sketch prototype system was developed on Windows2000 using technology of object-oriented-programming and c# programming language. |
