Method and system for drawing two-dimensional drawings in batches according to three-dimensional model of formwork

The invention relates to the technical field of modeling design, and particularly discloses a method and system for drawing two-dimensional drawings in batches according to mold frame three-dimensional models, and the method comprises the steps: obtaining a plurality of mold frame three-dimensional models, and recognizing a plurality of workpieces in each mold frame three-dimensional model; target surfaces with parts are screened out from the multiple surfaces of each workpiece, and a first two-dimensional diagram of each target surface is generated; performing feature recognition on all components on each target surface to obtain component feature information of each target surface; marking each part in the first two-dimensional diagram of the target surface according to the corresponding part feature information to obtain all second two-dimensional diagrams corresponding to each workpiece; and loading the second two-dimensional diagrams of all the workpieces in the plurality of mold frames into correspondin
