摘　　要：STEP中性文件作为STEP标准最为广泛的应用,成为当下主流CAD/CAM系统无一不支持的输入输出中性格式,无论是实现CAX系统间的数据集成,还是二次开发都需要解读STEP中性文件的信息模型。这里就此给出简要阐述,并介绍了STEP中性文件前后处理器的实现方法。STEP neutral file, as the most widely used application method of the STEP standard, has already become the basic in/output intermedium supported by main prevailing CAD/CAM system currently. Either to realize the integration of the product data between different CAX systems or to carry out the further development based on STEP requires the basic understand of the data structure represented by the STEP neutral file. A brief expatiation was given in this paper, as well as a introduction of the design of the pre/ postprocessor of the STEP neutral file.

关 键 词：STEP中性文件 信息模型 前后处理器
