Abstract: In recent years, the lightweight application in BIM models has been identified as the key direction of BIM technology application. In view of the problem that BIM model technology fails to create the diversified application scenarios, our enterprise starts from the actual business and regards the system research and development as the core to break the barriers among model file format conversion, BIM lightweight and cloud-render display. Combined with the multi-terminal interactive applications of PCs, mobiles and web-pages, the collaborative management of BIM application has been achieved, with great economic and social benefits in the engineering application.
