Summary:The invention discloses a BIM graphic engine loading method and device based on a WEB end, and the method comprises the steps: exporting an IFC file of a BIM model, and carrying out the analysis of the IFC file, and obtaining the attribute data of the BIM model; exporting a GLTF file of the BIM model, and analyzing according to the GLTF file to obtain geometric data of the BIM model; exporting a JSON (JavaScript Object Notation) file of the BIM model, and analyzing according to the JSON file to obtain material information of the BIM model; and associating the attribute data, the geometric data and the material information, and loading the attribute data, the geometric data and the material information so as to load the BIM model at a WEB end. According to the method, the technical problems that due to the fact that mapping resources and material parameters are lacked, Mesh grid material information of a component in a GLTF file loaded by an engine only has vertex colors, and the display effect is moderate are
