Abstract: Abstract: For the highway interchange project, because of its own complex spatial structure, miscellaneous intersection of curves, and complicated route across bridges, as well as the frequently varied elevation of bridge floor, great difficulties have been caused to the modeling work, and the design and modeling of large overpasses have always been a problem which urgently needs to be resolved in engineering field. Using BIM related software, according to the characteristics of highway interchange engineering, through the method of combining the BIM related modeling software with the visual programming plug-in Dynamo, this study discusses in detail the rapid construction method of real-time editable terrain model, main structure precision model and 3D model of the batch auxiliary facilities. The specific operation examples have shown that this method can improve the construction efficiency of the road interchange BIM model, there by promote the application of BIM technology in highway interchange engineering.
