基于Revit的二次开发在给排水管道优化中的研究

Research on Revit-based Secondary Development in the Optimization of Water Supply and Drainage Pipelines

针对建筑给排水管道设计中存在管道碰撞和交叉的问题,基于建筑信息模型(BIM),利用Revit开展给排水管道自动优化设计研究。首先对Revit软件的二次开发功能进行分析,然后基于管道优化的避让原则设置精确的避让管道过滤条件,并且重点研究管道自动避让的原理,最后基于Visual Studio 2015软件和Revit2016软件,使用C#语言开发管道自动避让插件。以两个工程实例来测试插件的稳定性和实用性,结果表明,开发的插件能够精确地进行碰撞管道的自动化避让。管道自动避让插件极大地提高了设计人员的工作效率,丰富了管道自动避让的方法。

Revit was used to carry out research on the automatic optimization design of water supply and drainage pipelines based on the building information model to solve the problems of pipe collision and crossing in the design of building water supply and drainage pipelines.Firstly,the secondary development function of the Revit software was analyzed.And then,a precise avoidance pipeline filtering method was established based on the avoidance principle of pipeline optimization.The method and principle of automatic avoidance of pipelines were focused on research.Finally,the plug-in was developed by using C#as the programming language and based on Visual Studio 2015 and Revit 2016.Moreover,taking two specific instances to illustrate the stability and applicability of this method.The results show that the program can realize automatic avoidance of collision pipelines accurately,which satisfies the principle of pipeline avoidance.It significantly improves the work efficiency of the designers,enrich the methods of automatic avoidance of pipelines.
