| With the rapid and stable development of the national economy and the continuous improvement of people’s living standards,people’s demand for architecture has not only met the basic living conditions,but also paid more attention to the shape,comfort and intelligence of the building.The diverse needs of the building place higher demands on the design of architecture,structure,and electromechanical expertise.The traditional twodimensional design mode can no longer meet the design requirements.BIM(Building Information Modeling)technology makes up for the two functions of visualization,graphics,simulation,controllability and cost.The lack of dimensional design reduces the probability of collision in the design and construction of integrated pipelines.However,in practical applications,the integrated pipeline optimization and adjustment process is repeated and error-prone,which leads to the inefficiency and accuracy of BIM technology.Therefore,it is particularly important to study the rapid optimization method based on BIM integrated pipeline.In the process of comprehensive pipeline design,shortening the design time of integrated pipelines can effectively improve the progress of the whole project,and the rapid adjustment and optimization of pipelines in the process of integrated pipeline design is an effective way to improve the efficiency of integrated pipeline design.Based on the in-depth study of the collision characteristics and adjustment optimization process based on Revit integrated pipeline model,this paper proposes a hybrid collision detection algorithm and pipeline adjustment optimization algorithm,and combines Revit secondary development technology to complete the secondary development based on the rapid optimization module of Revit pipeline to achieve rapid adjustment and optimization of integrated pipelines.The details are as follows:(1)In-depth study of the layout characteristics and geometric features of the integrated pipelines in the building model,combined with the theory of collision detection algorithms,proposed a hybrid collision detection algorithm based on spatial partitioning,bounding box and space geometry;and studying the comprehensive pipeline engineering avoidance rules On the basis of the combination of graphics theory,a pipeline adjustment optimization algorithm is proposed.(2)In-depth study of Revit API,using the C# programming language to redevelop the Revit software on the Visual Studio platform,using the hybrid collision detection algorithm constructed in this paper and the pipeline adjustment optimization algorithm based on engineering rules to realize the secondary development of the pipeline rapid optimization module..(3)Applying the pipeline rapid optimization module developed in this paper to a practical integrated pipeline project,the experimental results are analyzed from three aspects: collision detection accuracy,pipeline optimization process and pipeline optimization efficiency.At the same time,the traditional Revit and Navisworks integrated pipeline collision detection and optimization adjustment process are discussed,and the efficiency of the proposed method is summarized.The experimental results show that the hybrid collision detection algorithm proposed in this paper can quickly and accurately identify the pipelines that generate collisions.When using the automatic optimization plug-in to optimize the pipeline of a museum’s electromechanical project,the effective optimization rate is 93%.Compared with the traditional pipeline optimization methods based on Revit and Navisworks,the proposed method simplifies the pipeline optimization steps and improves the efficiency of integrated pipeline design. |
