Autodesk InfraWorks is conceptual design software for civil infrastructure that lets teams model, analyze, and visualize projects in real‑world context, aggregating GIS, terrain, and CAD data to rapidly explore roadway, rail, bridge, tunnel, and site options. It provides traffic and mobility simulation, sight‑distance and flood analysis, parametric bridges/tunnels, and photoreal visualizations, with workflows that complement detailed design in Civil 3D.
