Ceiling coating model building method based on Dynamo and Revit

The invention discloses a ceiling coating model building method based on Dynamo and Revit. The method comprises the steps that structural members are picked up to generate a structural member list; grouping and separating the structural component list; obtaining a structural entity list; the entities are packed towards the outer side, and a third-level entity packing list is obtained and combined; performing Boolean difference set processing on the entities to obtain an entity difference set list I; querying the highest geometric surface of the entity and performing thickening processing to obtain a geometric surface thickening combination list; boolean difference set processing is carried out again, and an intersecting geometric figure is obtained; judging by using a bounding box and carrying out Boolean difference set processing again; and naming and importing the natural sequence and the text to obtain a ceiling coating entity model. The method is high in modeling efficiency and rapid in later model modifi
