【摘要】 主要针对网络CAD知识库的特点，讨论了网络CAD原型系统的信息模型。在分析了知识存取与传递实现之后，提出了应用STEP标准所提供的中性机制，建立一个基于Internet/Intranet的知识库原型系统，并分析了集知识工程与信息集成的C/S机制，使得网络CAD技术中资源能否共享问题得到了很好的解决。更多还原

【Abstract】 This article mainly discusses the information module of prototype system for network CAD pointed to the knowledge warehouse traits of network CAD. After analyzing the knowledge saving, fetching and transferring implementation, puts forward a knowledge warehouse prototype system based on Internet/Intranet using neutral mechanism of STEP standard, at the same time, it analyzes C/S-based knowledge engineering and information integration, thus can solve the problem of resource sharing in network CAD technique.更多还原
