Aiming at the low efficiency of finite element model design and analysis software Abaqus, this article proposes a method of developing Revit-Abaqus structure model conversion interface. According to the Revit API customization technology provided by Autodesk, this article studies the conversion interface between Revit and Abaqus by C # programming language. By extracting the data of Revit structural physical model and structural analysis model, a runnable Python script is organized for Abaqus, and the model can be transformed from Revit to Abaqus, which improves the efficiency of modeling and calculation analysis.
