摘要:近年来，随着数字化技术的快速发展，BIM技术已被广泛应用于建筑领域。在应用Revit软件创建各建筑专业的BIM模型的过程中，由于道路曲折和高度变化较多，使用Revit手工建模存在一定的局限性，需要大量重复劳动、影响建模效率。本文主要研究基于Grasshopper和Revit软件快速生成道路BIM模型系统，通过参数化技术快速生成复杂的道路BIM模型的方式，来实现Revit软件快速建模，有效地提高了BIM建模效率，实现BIM技术对工程应用价值。应用结果表明，使用参数化技术对道路BIM模型快速生成可以有效提高工程设计阶段的效率以及信息化和数字化程度，为道路工程在设计阶段使用BIM技术提供了新方法。

Abstract: With the rapid development of Internet technology, BIM technology has been widely used in the field of construction in recent years. Revit is considered as the core BIM modeling software in China. In the process of applying Revit software to create BIM models of various architectural specialties, there are many changes in road curve and height, therefore manual modeling of Revit has certain limitations, which requires a lot of repetitive labor and affects the modeling efficiency. This paper mainly studies the rapid generation of road BIM model system based on Grasshopper and Revit software, and realizes the rapid modeling of Revit software through the generation of complex road BIM model through parameterization technology, which improves the efficiency of BIM modeling and obtains the application value of BIM technology to engineering. The application results show that the rapid generation of road BIM model by applying parameterization technology can effectively improve the efficiency and the degree of informatization and digitalization in the engineering design stage, which can provide a reference for applying BIM technology in the design stage of road engineering.
