【摘要】 针对虚拟装配系统中CAD模型数据转换的问题,提出了虚拟产品装配模型的层次化表达结构;开发了基于中性文件的模型转换接口,并对中性文件的结构、内容和形式以及虚拟环境下模型的重构进行了较深入的探讨。更多还原

【Abstract】 Aiming at the model transformation problem from CAD system to virtual assembly system,a multi-level representation structure of assembly model of virtual products was put forward,a model transformation interface based on neutral files was developed,and the structure,content and format of neutral files,information mapping and associating of model in the virtual environment were comparative-deeply discussed.更多还原
