Method for online editing BIM model based on B/S architecture and related equipment

The invention discloses a method and related equipment for online editing a BIM model based on a B/S architecture, and the method comprises the steps: receiving a BIM file through a web end, and generating a BIM map file corresponding to the BIM file through a server; and receiving an online editing operation for a three-dimensional BIM model formed based on the BIM map file through a web terminal. According to the method, the BIM model is edited online by an online BIM editor of a web end based on a B/S architecture, the edited BIM model is stored and displayed, and BIM software and plug-ins do not need to be installed. Wherein the online BIM editor can carry out three-dimensional rendering on a map file, a browser indexDB cache strategy is adopted, and a GLTF model is supported to set parameter translation, rotation, zooming, deletion, copying and LOD display levels. Meanwhile, the online BIM editor supports vector drawing, text labeling and picture uploading, and navigation points and navigation lines are
