A GIM based three-dimensional reconstruction and optimization method is proposed to address issues,addressed is-sues such as model redundancy,non standardization,and information loss in the process of power grid visualization reconstruc-tion.Build a substation component model based on GIM 3D collaborative design.By hierarchical partitioning,parameter model-ing,attribute warehousing,model assembly,and optimization,the GIM model is transformed into a standard FBX file,reduc-ing the amount of model data and achieving GIM model optimization.Through collaborative design from the solution library,a-chieve full cycle collaboration between electrical and civil engineering specialties,enhance the full process collaborative design of substations,and enhance the practicality of models.Taking a substation project as an example,it is shown that the GIM 3D re-construction technology has the advantages of controllable modeling accuracy,high reuse rate and standardized attribute stor-age.Through model optimization,the number of model sheets is reduced,and the reuse rate is improved.
