With this add-on, Highway Engineers and Bridge Engineers are treated separately to assume requirements for design practice and preference of technologies. It is a technology preview project at Autodesk Labs derived from a subset of Bridge Extension for Revit Structure 2010, a part of Subscription Advantage Pack 2010, which provides more robust bridge modeling capability and works with Bridge Modeler for AutoCAD Civil 3D 2010.
'Bridge Modeler for AutoCAD Civil 3D 2010 is a Civil 3D add-in module which can create simplified bridges directly from a Civil 3D corridor object. This preview add-on can be installed on Civil 3D 2010 and Civil 2010. Autodesk Labs, which provides access to previews of new technology, has made available 'Bridge Modeler for AutoCAD Civil 3D 2010'.
