Abstract: It is a valid way to cut down the time and capital cost of developing CAD/CAE data exchange interfaces to use mature commercial CAD products.Conforming to this matter of fact，a type of data exchange interface is implemented based on ACIS and the corresponding data exchange component InterOp，in order to provide CAD data exchange services for a CAE software，the High End Digital Prototyping（HEDP）.In addition，some basic data repair services are implemented using APIs provided by ACIS.Furnished with these services in the HEDP，imported models can be meshed successfully and exported models can be read by other CAD software.

摘要： 基于成熟的商业产品开发CAD/CAE数据转换接口是降低开发成本和周期的有效途径，基于ACIS及数据转换组件InterOp，开发了一类自主知识产权CAE软件高端数字样机（High End Digital Prototyping，HEDP）的CAD数据读写接口，并利用ACIS提供的接口实现了基本的几何修复功能。实验表明，利用算法导入的模型可在HEDP中顺利生成网格，导出的模型可为其他CAD系统正确读入。
