Abstract: By studying Dynamo program nodes, a parameterized modeling method of the wall based on Dynamo driven Revit is proposed to solve the key problems of low parameterization degree and low modeling efficiency of the wall modeling in substation area. This method includes logic relation and algorithm compilation in Dynamo, forming the workflow of parametric design and automatic modeling, which is more in line with the design habits of engineers,greatly improving the work efficiency, ensuring the accuracy of the model, and promoting the in-depth application of BIM technology in substation engineering.
