OpenBridge Modeler is designed to work concurrently with OpenRoads and OpenRail Designer.  It's the exact same data model.

Both products will be run concurrently sharing data throughout the design process.  Include both Bridge and Road seed files in your Project Setup.  

OpenBridge Modeler uses the geometry and corridor models from OpenRoads or OpenRail as the starting point for bridge design.  OpenBridge Modeler creates 3D BIM/Digital Twin-ready data for use in OpenRoads.
