摘　　要：随着ACIS环境应用的不断扩展,其模型文件的重要性也越来越突出。文中首先对各种常用的CAD模型数据格式进行了介绍,着重分析了ACIS SAT文件的结构,并对SAT文件、非SAT文件的读写以及模型实体的各种属性管理进行了详细阐述,提出了ACIS数据文件中模型管理的接口化模式。With the development of ACIS platform, the importance of its model file has become more and more obvious. This paper first introduces some widely used CAD model data formats, then analyses the structure of ACIS SAT file. This paper also discusses the implementation of reading and writing of SAT and NonSAT file, and the management of the attribute of model entities. Finally, the Interface design pattern of the management of model entities is presented.

关 键 词：ACIS SAT文件 模型实体 接口模式
