With the development of BIM technology, it is constantly applied to practical projects, and more and more small but effective design ideas can be realized through BIM technology. From the perspective of saving resources and reducing construction costs, this paper puts forward a method of automatic positioning of pipeline valves based on BIM technology. With the help of Dynamo visual programming, automatic positioning of single valve and multiple valves in Revit is gradually realized. Experimental results show that the method proposed in this paper is correct and feasible, which provides reference for the application of BIM technology in related fields.
