Abstract: According to the application requirements of Building Information Modeling(BIM) technology in intelligent integrated cabinet, this paper carried out the secondary development of BIM modeling auxiliary software based on Revit software, and implemented the development of three functional modules: integrated cabinet layout, equipment layout in cabinet and computer room layout generation; On this basis, combined with the actual project, the paper expounded the implementation process of software function. The example application shows that the aided design software can realize the rapid establishment of BIM of intelligent integrated cabinet, and provide reference for the full life cycle application of BIM technology in intelligent integrated cabinet.
