CAD/CAM系统间的数据交换接口

Data Exchange Interface Between CAD/CAM System

本文介绍了“基本图形交挟规范IGES的实现”这一“七五”项目中所定义的数据结构——广义多重表(GML)。以GML数据结构为基础建立起工GES的前、后处理器是解决在数据交换中数据丢失,以及前、后处理器不匹配的好方法。

This paper offers a detailed introduction of the Generalized Multi-List (GML), a data structure defined in the project 'the Implementation of Initial Graphics Exchange Specification'. To build up pie-and post-processors of IGES based on the common data structure, GML is a good means to avoid data loss and mismatching between pre-and post-processors duling data exchange.
