From Revit to Robot Structural Analysis: Automating Analytical Models for Complex Underground Subway Structures

Cerro Corá Station is not a typical engineering project. It’s a 50-meter-deep and 50-meter-diameter cylindrical subway station, designed to accommodate two future subway lines intersecting within a single structural volume. The central structural element? A massive cylindrical retaining wall with four large structural openings—a challenge for any engineer aiming to maintain analytical accuracy and performance. Manually modeling such a structure analytically is time-consuming and a potential source of serious design errors. To overcome this, we developed a complete automated and interoperable workflow that begins with the physical geometry in Revit software, uses custom Dynamo routines to generate the analytical model—including the segmental wall with its four massive openings—and seamlessly transfers everything into Robot Structural Analysis 2025 software for structural analysis and verification.
