Rapid Three-Dimensional Representation Of Railway Station In The Phase Of Route Overall Design

At present,the emerging three-dimensional design model has become an important direction of development,and the subway station as a key design of individual buildings of urban rail transit lines is one of the important parts of the three-dimensional design of urban rail transit.As the core modeling software of BIM technology,Revit has the characteristics of visualization,parameterization and collaboration.Using Rviet software to create subway station model can greatly improve the modeling efficiency on the basis of improving the authenticity of the model.Based on this idea,this paper studies the rapid generation of subway station model with the theme of "rapid three-dimensional expression of subway station in the stage of overall line design".The main contents and achievements of this paper are as follows:(1)By analyzing and studying the main body and internal structures of various typical stations in subway stations,the external structure,component composition,component parameters and constraints among components of subway stations are analyzed and summarized.(2)By analyzing and summarizing the component composition,component parameters and constraints among components of subway stations,the parametric family library of subway station components is established according to their own characteristics and different attributes of Revit family template.When the family library is created,the required family components can be directly transferred to create the model in engineering design,which can reduce the workload and improve the efficiency of modeling.(3)By using the secondary development method of Revit,the placement of components of subway station is realized,and the rapid generation of BIM models of subway underground station,ground station and elevated station are also realized.
