以中间文件为媒介的数据交换接口

Data Exchange Interface Based on Neutral File

数据交换接口是集成化 CAD 研究领域中的主要研究方向之一。本文讨论了目前国际上使用最广泛的数据交换格式——IGES 的发展和它的技术要点,介绍了未来的国际标准 STEP 的实现概念。最后,依据IGES4.0版为工程数据库系统 WEDBS 开发了 IGES 接口。

Data exchange interface is a major topic in the realm of CAD-integration.IGES is the most widely used format for data exchange in the world.This paper discusses the development and implementation of IGES.It also introduces the idea of the implementation of STEP—the future international standard.The last part of the paper is an introduction of an IGES interface for the engineering database WEDBS,which is developed according to IGES Version 4.0.
