Device and method for dynamic association of two-dimensional and three-dimensional engineering data based on building information modeling lightweight

The invention belongs to the technical field of construction systems, and particularly relates to a device and a method for dynamic association of two-dimensional and three-dimensional engineering data based on BIM (building information modeling) lightweight. The device comprises a drawing association module, a synchronous model module and a data dynamic association module, wherein the drawing association module is used for a first step, the synchronous model module is used for a second step, and the data dynamic association module is used for a third step. The device and the method solve the problems that BIM based design document informatization management is absent, consequently, corresponding design documents and engineering data cannot be called by positioning corresponding positions in BIM, and two-dimensional and three-dimensional linkage cannot be realized in the prior art. The device and the method have the advantages of high informationization degree, convenience in dynamic maintenance, customized d
