Abstract: Develop the connection software between Revit and PKPM, add all the load and PM ＆ SATWE parameters in Revit, then output the “. jws” file in the form of overlay. That is, complete preprocessing of SATWE software in Revit. After the software development and the overall test is passed, the comparison and verification are carried out.Three completed concrete frame structures are adopted, and after manually modeling in Revit, the “. jws” is output and then calculated. Compared with the original SATWE calculation results, the results are 100% consistent. In the actual project, three small and medium-sized concrete frame structures were selected for BIM forward design.After artificial modeling in Revit, the model was adjusted repeatedly and the “. jws” was output to SATWE, and the structural construction drawings were created manually in Revit. The results show that it is feasible to complete all the preprocessing work of the structural calculation software in Revit so as to realize the connection with the structural calculation software. It can not only be applied to the BIM forward design of the actual structure, but also be no less efficient than the two-dimensional CAD design.
