In recent years, BIM technology develops rapidly in the construction industry.As the representative software of the application of BIM technology, Revit can realize collaborative design of architecture, structure, construction, and MEP, and has been widely used in building design field. However, Revit does not meet the building code well in our country currently, so the structure analysis become a lonely island in the entire three-dimensional model information chain, resulting in a large number of domestic structural model can't apply collaborative design in last decade. PKPM structural analysis software combines closely with Chinese building code, and it is widely used. Therefore, it is of great significance to develop a bi-directional data interface software between PKPM and Revit. This article develops a bi-directional data interface software between PKPM and Revit on the Revit platform, and discusses several key issues in the software, along with the detailed solutions.
