The seamless integration of structural analysis and detailed fabrication documentation is pivotal for modern building design and delivery. This research paper presents an in-depth comparative analysis of ETABS and Bentley ProStructures, two leading software solutions in structural engineering and Building Information Modeling (BIM). ETABS specializes in the analysis and codebased design of multi-storey buildings, while ProStructures excels in parametric 3D detailing and the generation of shop drawings and fabrication data. The study systematically reviews the core capabilities of each platform, evaluates their interoperability—particularly via Industry Foundation Classes (IFC)—and dissects a typical ETABS-to-ProStructures workflow. The findings demonstrate that while each tool offers unique strengths and limitations, their combined deployment through a robust IFC-mediated pipeline enables a BIMoriented, efficient, and quality-assured workflow from analysis to detailing. The research further provides best-practice recommendations for engineers and detailers seeking to maximize the advantages of both platforms in contemporary construction projects
