STEP文件创建研究

Study On Creating STEP File

为了建立符合STEP(STandard Exchange of Product data model)标准的企业信息文件,提出了基于STDeveloper工具的STEP文件创建方法.给出了从活动模型到参考模型、再到解释模型的EXPRESS信息建模法.结合实例,阐述了利用EXPRESS编译器、ROSE类库,C++编程创建STEP中性文件的过程.实现了用STEP文件表达企业信息,对推广应用STEP标准、企业信息互操作有重要意义.

The method of creating STEP file, based on ST-Developer, was proposed for the expression of enterprise information to meet this criteria. The modeling process, from the activity model to the reference model and then to the interpretation model, was given. The procedure to generate file, using the EXPRESS compilers, ROSE class library and C++, was presented with examples. The enterprise information expressed by STEP come ture. It is important for STEP to be put into use and information to be interoperated.
