【摘要】 研究语义级的三维CAD建模方法,并在三维CAD智能培训平台上进行了应用。首先介绍了基于XML的数据级建模和基于Sem antic W eb的语义级建模;然后探讨了面向三维CAD的静态的几何特征建模和动态的造型过程建模;最后基于语义建模在三维CAD系统环境下开发了智能培训系统,验证了本文方法的有效性。更多还原

【Abstract】 3D CAD semantic modeling and its application on CAD intelligent training platform are studied in this(paper.) Firstly,data modeling based on XML and semantic modeling based on semantic web are introduced.Secondly,static(geometry) feature modeling and dynamic semantic process modeling are presented.Finally,a training system based on(semantic) modeling is developed in the environment of 3D CAD,and shows the method mentioned in this paper to be effective.更多还原
