In this session of our foundational training series, we introduce the Bridge Path Coordinate System in LARSA 4D—an essential tool for accurately modeling curved or complex bridge geometries. Instead of relying on traditional X, Y, Z coordinates, this tool uses station, transverse, and elevation inputs aligned with your bridge’s centerline—making joint placement, supports, and load application more intuitive and accurate. This tutorial walks you through setting up a bridge path, editing horizontal geometry, assigning the coordinate system to your model, and even converting straight bridge models into curved ones. Perfect for engineers working on curved girder or segmental bridge designs, this video helps you unlock a more intuitive and accurate modeling workflow.
