摘要
BIM技术的蓬勃发展,实现了工程设计从二维图纸到三维模型的跃迁,但存在建模工作量大、二次开发门坎高等问题。针对水运工程设计建模中手动建模工作复杂、重复构件多的问题,引入Dynamo可视化编程平台。通过可视化编程和参数化建模方法,利用码头前沿线、陆域地形等边界条件计算出模型构件的相对位置关系,利用Dynamo节点调用Revit族库建立码头前沿框架模型并修改模型参数,解决了三维手动建模重复劳动且不易修改的问题,提高建模速度和精度,为BIM技术在水运工程三维建模中的深入应用提供借鉴和参考。
The vigorous development of BIM technology realizes the transition of engineering design from 2 D drawing to 3 D model,but there is a large amount of modeling work and the secondary development is a high threshold.Aiming at the problems of complex manual modeling and many repetitive components in the design modeling of water transportation engineering,we introduce Dynamo visual programming platform,apply the visual programming and parameterized modeling method,calculate the relative position relationship of model components by boundary conditions along the front of wharf and land terrain,use Dynamo node to call Revit family library to set up the model of wharf frontier frame and modify the model parameters,solve the problem of repeated work and error of 3 D manual modeling,and improve the speed and precision of modeling.It provides references for the deep application of BIM technology in the 3 D modeling of water transport engineering.
