In order to meet the BIM modeling requirements for railway overhead contact system design and solve the current difficulties in implementing the forward design process such as slow 3D modeling speed and low parameterization degree of OCS,a data-based parameterized modeling solution is proposed based on the modeling process of the OCS and the work content of the designers.With Openrail Designer software,the OCS 3D digital design software is developed.The developed program fulfills the functions such as obtaining professional interface data for collaborative platforms including roads,bridges and tunnels,parameterized design and management of OCS components,pillar layout,automatic assembly of cantilevers and suspensions,synchronization of 2D and 3D drawings,and output of engineering quantity lists.A detailed introduction is given to the key technologies of parameterized modeling of components such as pillars,cantilevers and compensation devices,and the methods for specialty data collaboration,automatic creation of 3D models of OCS,and binding of 2D and 3D models,which promotes the specialty collaborative interaction of data,improves the efficiency of BIM modeling and provide effective tool support for forward BIM design of OCS.
