Note: you will need to login to Subscription to download … Autodesk® Shared Reference Point 2015 provides functionality to export known points and elevation from AutoCAD® Civil 3D software to an external file, in which Autodesk® Revit® software can import and setup a “Shared Coordinate System.” This enables the collaboration of exported RVT, DWG and NWC files back to AutoCAD Civil 3D and to coordinate models in Autodesk® Navisworks® software.
I just tried it but it seems like they moved the link.
Strange, it still works for me. It will only work if you are entitled to it on Subscription (infrastructure suites probably…)
