一种基于IFC的地形模型共享方法

A method of terrain model sharing based on IFC

建筑信息模型实现信息数据共享的方式主要包括:使用专用中间文件格式和使用公共数据模型格式等。针对专用中间文件格式DXF在传递模型属性信息时存在信息丢失的情况,基于IFC实现地形模型跨平台共享,且保留了模型属性信息的完整性。结果表明,IFC作为一种开放的建筑产品数据交换和表达的国际标准,为BIM应用系统之间模型信息数据的共享提供了一种思路。研究成果对于测绘单位开展BIM工作具有一定的借鉴意义。

The ways of building information model to realize information data sharing mainly include:using special intermediate file format and using public data model format.In view of the fact that DXF,a special intermediate file format,has lost information when transferring model attribute information,the terrain model is shared across platforms based on IFC,and the integrity of model attribute information is preserved.The results show that IFC,as an open international standard for data exchange and expression of building products,provides an idea for model information data sharing between BIM application systems.The research results have certain reference significance for surveying and mapping units to carry out BIM work.
