摘　　要：以CATIA中建立的船体模型为数据源,分析其输出的STP标准格式文件数据结构,建立基于STP文件的不同实体对象的组织关系,并应用OpenCasCade开源包编写解析STP文件的程序,对STP文件进行解析,重构文件组织结构,实现文件数据的信息提取,生成验证效果良好的三维几何模型,为不同软件之间结构模型交换提供解决方案。The hull model created in CATIA is regarded as the data source,and the organizational relation of different entity objects bases on STP files,the output of CATIA,is established by analyzing the STP standard format file data structure.By writing programs for parsing STP file with OpenCasCade open source package,the STP file is parsed and file organization structure is reformed to realize the information extracting of the file data.The file data generates three-dimensional geometric model that can be verified,which provided a solution for the hull model exchanging between different softwares.
