摘　　要：数字孪生建筑对于BIM建模提出了更高的要求,采用传统建模方法精度不足且工作效率低。针对这一问题,基于Dynamo平台编制了参数化建模程序并应用于某学校游泳馆屋面钢结构网架建模。结果表明,基于参数化建模程序能够完成钢结构网架BIM模型参数化生成,实现了工程量明细表信息单的自动生成,还能够根据图纸自动识别并创建对应型号的网架构件,建模效率和精度大幅提升,在钢结构网架构件加工生产及项目建成后的运维管理等方面也能发挥重要作用。Digital twin buildings put forward higher requirements for BIM modeling,and the traditional modeling methods are inaccurate and inefficient.In order to solve this problem,taking the creation of steel structure grid model as an example,a parametric modeling program was compiled based on the Dynamo platform,which realized the automatic generation of steel structure grid BIM model and one-click export of engineering quantity schedule,and at the same time described in detail the key nodes used in the program,and finally applied the program to the creation of steel structure grid model on the roof of a school swimming pool.The results show that the use of parametric modeling can greatly improve the modeling accuracy and efficiency,broaden the application scope of Dynamo in digital twin buildings,and provide a reference for the application of parametric modeling in steel structure grid modeling.
