Research on data lightweighting method of BIM model based on IFC

At present, the application of building information modeling (BIM) in projects is increasing in China, and the large-scale BIM volume model with redundant data seriously restricts the use of BIM technology in practical applications. In order to load BIM models more conveniently, achieve rapid online transmission, and reduce the resource consumption of computers and mobile devices, it is proposed to lightweight process BIM models by parsing and extracting IFC file information, reconstructing models, and eliminating redundant model components.
