基于网络的协同CAD特征建模技术研究

Study on Technology of Feature-based Modeling of Collaborative CAD Based on the Network

探讨了协同工作模式和建模的需求,论述了一种结合和结构优势的三维协同建模系统的结构和实现。通过对三维参数化C/SB/SCAD特征技术、网络通信技术和特征编码技术等关键技术的研究初步实现了局域网环境下零件级产品协同参数化造型设计和上的模型信,Internet息发布。

This paper analyzes the demands of the market in this area about the mode and modeling of collaborative design, then discusses the architecture and realization of a 3D collaborative CAD system combined with the advantage of Client/Server and Browser/Server architecture.Via the research of several key techniques, including the technology of 3-D parametrized feature,network communication and feature coding, we promote the cooperative design architecture of parametrized modeling on part level in the LAN and the publication of model information on Internet.
