Building a campus platform with the characteristics of "3D visualization", "informatization", and "digitalization" is the foundation of smart campus construction. Most existing campus platforms used traditional modeling tools and GIS platforms built with C / S architecture. There are problems such as lack of unified integration of model information, tending to be flat, low level of visualization, and lack of cross-platform. BIM technology has effectively improved the level of construction industry informatization because of its data integration model,This paper combines the advantages of BIM technology two- and three-dimensional information integration and WebGIS-Cesium framework plug-in-free, cross-platform advantages, using our school as a prototype for modeling and Revit Secondary development, file streaming and other technologies to develop a campus platform based on B / S architecture mode with both visualization, informatization, and cross-platform capabilities. This System platform designed the map display module, building BIM information query module, and then realize the sub functions of these modules.Through testing, the designed system works reliably and feasible to meet the needs of campus platform.
