Then it presents the application situation of many important standards , and focuses on analyzing the mapping relationship between files . thus , it builds the method for reading and writing operations on the original library information data and realizes a series of information management work of the parts library data files , such as search , input and refreshment 论文阐述了不同标准的应用环境,重点分析了文件间的映射关系,建立了对原有库信息数据的读写操作和相应的数据转换途径,并完善了零件库数据文件的查询、录入、更新等一系列信息的管理工作。
2 . dynamically organizing cad graphics information taking the product structure tree as data structure , which links assembly information and geometry information ) the gathering agent can automatically converts assembled relationship into hyperlink relationship of vrml files , so the system could implement a strategy of integrated and visualized sharing approach based on the web - based visualized product structure tree . 3 产品cad图形信息的动态组织建立以产品结构树为中心的数据组织结构,通过采集agent自动地将产品的装配关系转化为相关零部件vrml文件间的超链接关系,使系统能以“可视化结构树”的形式进行有效地产品cad图形信息发布。
