Abstract: The problem of efficiency of girder reinforcement design in Revit environment is a top concern of structural majors.This paper presents an Advanced Plane Integral Drawing Method and a set of assistant software for this method which is developed based on Revit secondary development technology.This paper also presents a set of methods for structural engineers to add reinforcement tags, to link calculation results, to mark all the girder spans, to add reinforcement information to girder elements directly, and etc.Operation process and operation mode of this method is almost the same to the traditional method, and this method satisfies the need for repeated modifications.This method not only inherits the traditional design habits and examining habits and shortens engineer′s adaptation period, but also improves engineer′s working efficiency.Besides, because every girder element is provided with complete reinforcement information, 3D reinforcement can be easily generated by software.
