摘要:目前Revit对于网架结构的建模存在很大问题。常规手动建模的方式几乎难以完成，而采用体量建模，所有的网架球和杆件类型相同，不符合工程实际。为了解决这一难题，本文分别研究了Revit Extensions和Dynamo软件进行网架结构的建模解决方法，重点介绍了可视化编程工具Dynamo在Revit自动建模上的应用。对于设计人员，Dynamo参数化编程工具相对容易掌握。本文编制的Dynamo程序，通过读取网架数据，能自动生成精确的网架模型，网架球和杆件的尺寸及定位与实际情况相符，提高了建模效率和模型质量。

Abstract: At present, Revit has great problems in the modeling of grid structure. The conventional manual modeling approach is almost impossible to complete, while adopting the conceptual mass modeling will lead to all the grid balls and bars the same type, which is not in line with the engineering practice. For solving the problem, this paper studies the modeling method of grid structure by using Revit Extensions and Dynamo software respectively, and focuses on introducing the application of visual programming tool Dynamo in Revit automatic modeling. For designers, Dynamo parameterizd tools are relatively easier to master. The Dynamo program developed in this paper can automatically generate an accurate grid structure model by reading data of grid structure. The size and location of the grid balls and bars are in accordance with the actual situation, and the efficiency of modeling and the quality of the model are improved.
