Analysis of Intelligent Rapid Bridge Modeling Technology Based on BIM

采用Revit软件平台和C#编程语言完成了桥梁三维模型的智能化快速创建,完善了Revit线路计算功能,实现了基于线路平纵曲线要素信息的线路坐标、切线方位角以及标高的自动计算,结合桥梁布置信息自动计算了各个构件位置参数并自动放置,利用属性参数驱动构件完成了全桥模型的创建。同时实现了构件的自动编码,定位坐标和角点坐标的自动导出,工程量信息的精确提取。极大地提高了建模灵活性和效率,具有广阔的应用前景。

By using the Revit software platform and C# programming language, three-dimensional models of high way, railway and continuous beam bridge have been completed intelligently rapidly. Revit circuit calculation function has been improved, automatic calculation of line coordinates, tangent azimuth and elevation are realized through line horizontal and vertical curve element information. Combined with the bridge layout information, the individual components’ position parameters have been calculated and placed automatically. The whole bridge model are built by attribute parameter driver component. At the same time, components are coded automatically, both location and corner coordinates are exported automatically, and engineering quantity information are extracted correctly. The technology greatly improved the modeling flexibility and efficiency and has bright application prospect.
