基于数据库的全参数化CAD系统的应用

The application of all-parameterized CAD system based on data base

实现产品设计系列化是提高设计效率的有效途径,参数化计算机绘图与数据库资源的有效连接是实现设计系列化的最好方法。介绍了以一个企业的相似产品进行分组,建立产品全信息数据库而实现全参数化 CAD的一种方法,同时介绍了一种适合系列化全参数化 CAD的基本原理、数据结构和相关技术。

Realizing the seriation of product design is the effective way in improving design efficiency and the effec- tive link between parameterized computer drawing and Data-base resources is the best method of accomplishing the seriation of product design. This paper,by means of dividing similar products into groups in an enterprise, introduces a methed of realizing all-parameterized CAD based on all-information Data base of products. In the meantime,it presents the fundamental data structure and related techniques suitable seriation and all-parameterized CAD.
