The invention relates to a binary storage format of BIM model data. The binary storage format comprises a model component number, a component basic parameter, a component SubMesh number, a component SubMesh parameter, a component attribute group number, a component attribute group parameter, a material number, a material basic parameter, a material mapping parameter and a model sharing map. The model sharing map refers to that maps used by all components in the model are stored in a folder named by a data document in the format at the position where data in the format is stored. The data format is public and easy to understand; a user does not need to read a large number of SDKs or protocol standards, and data can be quickly taken out only according to various numbers and parameter types;data is stored in a binary mode, and space is saved; the complete attribute of Revit are completed, materials are simplified, material data are standardized, redundant invalid content is reduced, meanwhile, it is guaranteed t
