[0041] The wind turbine concrete tower is composed of multiple pipe segments arranged in a regular and repetitive manner according to a certain proportion. The geometric characteristics of each component can be accurately described by defining different parameters. This design allows the establishment of a three-dimensional scene using a parameter-driven model. Users can set the parameters of each pipe segment by uploading an Excel spreadsheet, thereby realizing the automatic generation of the entire concrete tower model. Parametric modeling summarizes the changing geometric features from similar models and abstracts them into controllable mathematical parameters. By adjusting these parameters, different geometric models can be generated. For complex engineering building models, a combined modeling method is usually used to decompose the entire model into a series of components according to architectural rules, and use combined parameters to describe their arrangement and splicing.
