【摘要】 依据IFC/MVD方法所产生的BIM数据交换接口存在仅适用某一种BIM应用,不支持共享BIM数据库的缺陷。基于对BIM交换数据几何功能层次的定义,本文将IFC4.0所提供的3D几何描述类分为三个层次:可视化层、可参照层、和可编辑层,简述了按照几何功能层次划分使用IFC几何描述类开发BIM交换数据接口的可行性,并进一步分析了依据几何功能层次所划分的BIM数据接口对多种BIM应用的适应性。更多还原

【Abstract】 BIM date exchange interface made by IFC/MVD has some faultiness such as suit for only one BIM use,without the ability to support BIM database,etc..We present a new method to structure BIM data exchange interface,by divide geometry classes into three level by its geometry function,viewable level,referenceable level,and editable level.There are all three BIM data exchange interface,and each interface will only use IFC geometry classes with the same geometry function level.We have analyzed the adaptability of such interfaces for various BIM uses.更多还原
