摘要:为了推进路桥工程建设领域的信息化进程，提高道路桥梁工程的建设管理水平，特对桥梁参数化建模技术展开深入研究。本文通过深入剖析基于Revit的可视化编程插件Dynamo的工作原理，结合参数化建模的应用实例，提出了一种基于Dynamo插件的预制箱梁BIM模型参数化建模方法，实现了预制箱梁BIM模型的快速精准建模，避免了缓和曲线段预制箱梁建模过程中以直代曲产生的误差，大大提高了建模的效率及建模精度，为类似工程的BIM建模工作提供了技术支持。
Abstract: In order to promote the informatization process of road and bridge construction and improve the management level of road and bridge construction, parametric bridge modeling technology is studied in depth. In this paper, through an in-depth analysis of the working principle of the Revit-based visual programming plug-in Dynamo, combined with the application examples of parametric modeling, a method of parametric modeling of the precast box girder BIM model based on the Dynamo plug-in is proposed, and the BIM model of the precast box girder is realized. The rapid and accurate modeling avoids the error caused by the direct substitution of the curve in the modeling process of the prefabricated box girder of the relaxation curve section, which greatly improves the modeling efficiency and modeling accuracy, and provides technical support for the BIM modeling work of similar projects.
