可视化约束程序编程环境的设计与实现

Design and Implementation of Visual Constraint Programming Enviroment

该文提出了一种应用于多数化CAD系统的面向约束的程序设计思想，开发了一个实用的可视化约束程序编程环境。不仅简化了用户在参数化图形设计过程中大量约束程序的编程，而且提出了一种应用于参数化CAD系统设计图形约束程序的可视化方法。

This paper has presented a constraint oriented programming method by using a parametric CAD system, and developed a practical Visual Constraint Programming Enviroment, whieh greaily simplifies the programming of a lot of constraint programs for the users in the process of parametric graphic designing.And this paper has also offered a visual aPproach which can be used in parametric CAD system designing graphic constraint program.
