BIM (Building Information Modeling) automatic modeling method for hollow stone curtain wall

The invention discloses a BIM automatic modeling method for a hollowed-out stone curtain wall, and the method comprises the steps: arranging and editing the design data of the hollowed-out stone curtain wall, the design data comprising a curtain wall surface boundary, a hollowed-out pattern, and a panel typesetting reference mark; the design data are imported into a Revit platform, and a Dynamo tool is used for separating the boundary of the curtain wall face, the hollowed-out pattern and the panel typesetting reference mark; creating a curtain wall surface curved surface based on the separated curtain wall surface boundary, creating a panel overall typesetting curved surface based on the separated panel typesetting reference mark, and performing intersection operation on the curtain wall surface curved surface and the panel overall typesetting curved surface to form a curtain wall surface basic panel unit curved surface; creating a hollow cylinder model based on the separated hollow pattern; performing inter
