Abstract: A Building Information Modeling (BIM)-based intelligent drafting method for prefabricated buildings includes the following steps: step 1: extracting building model information; step 2: modeling the building model information, where Revit elements are divided into model elements, datum elements, and view-specific elements; step 3: extracting element management information based on a BIM model; step 4: extracting a sub-model view based on a BIM global model; step 5: performing BIM-based three-dimensional (3D) parametric modeling; and step 6: performing intelligent drafting for the prefabricated buildings: extracting structure information by an integrated platform for production, sales, and construction of the prefabricated buildings, extracting architectural, structural and mechanical electrical BIM models and generating drawings with a quick response (QR) code.
