IGES文件在非均质实体保存与读取中的应用

The applications of IGES file in saving and reading heterogeneous object

非均质实体是一种具有多种优良性能的新型构件,但由于其数据处理和记录方式与常规均质实体具有本质区别,导致了非均质实体建模软件与其它常规CAD/CAM软件之间的数据传输与数据交换十分困难,严重影响着非均质实体建模软件的通用性.针对这一问题,基于IGES文件,提出了一种能够保存非均质实体模型的几何信息和材质信息的方法,解决了非均质实体的保存与读取以及数据共享问题,实现了不同平台间的非均质材料实体的数据交换.

Heterogeneous object（HO） is an innovative component, which often shows multiple special performances.But data processing and record are essentially differential between heterogeneous and homogeneous object, so it is very difficult to transmit and exchange data between HO modeling software and other conventional CAD/CAM software, and it seriously limits the generality of HO modeling software. In order to solve this problem, a method, based on IGES file,is represented which can save geometrical and material information in HO completely. It solves HO problems of saving,reading and data sharing and realizes data exchange between the different platforms.
