Parametric Modeling for Bridge structures Based on Dynamo

In Revit software, the bridge model is not accurate enough due to the need to manually pick the location of the bridge ’’double slope" components. In order to improve the accuracy of the bridge model, taking Huzhou inner ring Fenghe bridge as an example, the three-dimensional model of the bridge is accurately established by using the open source tool dynamo. In the process of building the model, the data transmission of Excel, Revit and dynamo is completed by calling and combining dynamo nodes. This updated "Data-Driven" method can quickly and accurately locate these components of the bridge, and effectively improve the quality of the bridge model.
