Automatic hooking method and system for BIM model and project main data

The invention belongs to the technical field of building information project management, and particularly relates to an automatic hooking method and system of a BIM model and project main data, and the automatic hooking method of the BIM model and the project main data comprises the following steps: creating a mapping relation between a project main data model and component attributes; creating a data hitching maintenance name; filling in a tree structure maintenance name or selecting preset tree structure maintenance; selecting a BIM model file and selecting a mapping relation of an associated maintenance data tree structure, and creating data hitching maintenance; and maintaining the automatic hitching BIM model and the project main data according to the data hitching. The automatic hooking method of the BIM model and the project main data is superior to the prior art in the aspects of improving the working efficiency, reducing the error risk, ensuring the data consistency, being easy to manage, improving t
