摘要
结合当前三维零件设计中协同工作的需求 ,基于三维参数化特征设计、特征编码技术和网络通信技术 ,研究开发了具有 C/ S体系结构的三维零件设计工具 .利用泛命令的思想 ,将造型命令划分为网络命令和本地命令 ,大大减少了网络中传递的数据量 ;通过组织相应的网络数据结构 。
The concept of custom commands is proposed to classify modeling commands into 'net commands ' and 'local commands', so that the quantities of data being transmitted among clients were reduced greatly. And in this paper, the corresponding data structures for net communications were organized to meet the requirements of collaborative design. Based on the above research and the technology of feature based modeling, a 3D part collaborative design tool with C/S architecture is developed, which implemented the collaborative parametric design of part level products in a network environment.
