BIM model resource management method and system

The invention relates to the technical field of building model management, and particularly discloses a BIM model resource management method and system, and the method comprises the steps: receiving an access request containing user identity information, opening a query port according to the user identity information, and receiving a query instruction containing a feature array based on the query port; traversing a feature table according to a feature array in the query instruction in sequence, and positioning a target model; and displaying the target model and opening an operation port, receiving an operation instruction sent by a user based on the operation port, and executing a corresponding action according to the operation instruction. The characteristic values of the sub-components are established through the mechanical input values, so that technicians in the field can perform simple mechanical calculation on an actual object and determine the characteristic values of the sub-components when positionin
