Parametric Modeling of Polyhedron Based on Revit

In view of the characteristics of polyhedron spatial structure, such as simple structure, high repeatability, less node types and joined members, good bearing, seismic resistance and ductility, the parametric modeling of polyhedron spatial structure based on BIM technology is studied. Based on the programming interface (API) provided by Revit, and combined with the mathematical theory of Weaire Phelan (WP) like polyhedron, a parametric modeling plug-in of the polyhedron is developed in Revit through the WP like controlled by the window program to realize the parametric selection and visual modeling of the polyhedron basic cell and basic combination. The correctness of the plug-in in WP like polyhedron selection process is verified by an example, which provides a convenient and fast visual design method for designers.
