Three-dimensional design modeling method for power distribution network equipment

The invention provides a power distribution network equipment three-dimensional design modeling method, and relates to the field of power distribution network three-dimensional modeling. The three-dimensional design modeling method for the power distribution network equipment comprises the following steps that 1, line basic information is obtained from a two-dimensional design result, and information is obtained from a two-dimensional design result of a power distribution network overhead project and serves as basic data for three-dimensional modeling; firstly, a tower component material model library needs to be established. Through obtaining line basic information from a two-dimensional design result and establishing an overhead part model library, data such as a line path diagram, point position coordinates and a material detail list are obtained from the two-dimensional design result, and line net rack information of a current project and material detail information of each tower part are obtained. And a
