摘　　要：作为城市轨道交通BIM设计的常用平台之一,Revit在建筑、结构等专业工程方面内置了丰富的设计工具,可实现高效BIM建模。而城市轨道交通轨道工程是一种空间曲线下的带状工程,现有Revit平台无法满足专业设计人员的高效建模需求。针对这一问题,根据轨道专业设计经验,结合Revit平台软件特点,提出一种Revit平台下快速实现轨道BIM建模的方法。通过Revit平台下的Dynamo可视化编程工具开发的专用工具,实现对线路平纵断面基础数据的读取,以及直接计算出线路空间位置及方向,然后自动调用各类轨道自适应构件,进行钢轨、轨枕扣件及道床的布置,实现轨道BIM高效建模。As one of commonly used platforms for BIM design of urban rail transit, Revit has built-in rich design tools in professional engineering such as architecture and structure, which can realize efficient BIM modeling. The urban rail transit track project is belt-shaped under a spatial curve, and the existing Revit platform cannot meet the efficient modeling needs of professional designers. In response to this problem, based on the professional design experience of the track, combined with the characteristics of the software of the Revit platform, this paper proposed a method to quickly realize the BIM modeling of the track under the Revit platform. Through the Dynamo visual programming tool under the Revit platform, a special tool was developed to read the basic data of the horizontal and vertical section of the line and directly calculate the line space position and direction, and then automatically called various rail Revit adaptive components for rails and sleepers. The arrangement of fasteners and track bed realizes the efficient modeling of track BIM, which can a provide reference for the BIM design of similar projects.
