Abstract: This paper has studied and developed a BIM-based parametric plug-in for pipeline hangers. The plug--in is for the modeling software of Revit to create a parametric pipeline hanger models. Through the secondary development of Revit, the pipeline hanger layout function is realized to improve the construction efficiency and precision of pipeline hanger layout in installation engineering. Meanwhile, the checking function of pipeline hanger is realized for the convenience of the optimization of design scheme.
