Three-Dimensional Parametric Modeling of Shield Tunnels Based on BIM Technology
With the popularization and application of BIM technology,an increasing number of three-dimensional modeling methods have emerged,among which Revit software is the most widely used.However,Revit software alone has not provided a satisfactory solution for modeling shield tunnels.To ensure the accuracy of the three-dimensional model of shield tunnels,conducts an in-depth study on the three-di-mensional parametric modeling of shield tunnels.By leveraging Dynamo visual programming and integrating it with Revit software,the corre-sponding parametric modeling program can be directly written to achieve rapid three-dimensional parametric modeling of shield tunnels.This approach resolves the issue of Revit's inability to perform three-dimensional spatial curve modeling.After validation,it has been demonstrated that by simply adjusting the parameters in the Excel spreadsheet after the completion of the three-dimensional parametric programming,mod-els of shield tunnels with varying parameters can be easily and swiftly generated.This approach is user-friendly,straightforward to adopt,and has a low barrier to entry,making it highly extensible and suitable for widespread adoption.
