Abstract: Focusing on problems of low standardization, low efficiency and low accuracy of manual modelled models, this paper adopts the method of using basic data platform with plug-in, taking secondary development based on Revit, which efficiently completes the plug-ins for civil engineering, reinforcement, electromechanical and decoration modelling. Integrating with the experience of China Construction Eighth Engineering Bureau in BIM practice, the software archives Revit auto-modelling based on CAD files. For improving the efficiencies, different tools are developed for different disciplines and scenarios. Therefore, the modelling efficiencies are increased from fast-tract, standardization, and automation.
