When I first heard about Civil3D, I heard that you would be able to modify
the vertical design of a road and it would update a surface. I assume this
would be through attaching a grading object to the vertical design somehow.
Is this currently available or is it slated for future versions or was I
simply mistaken and this is not planned at all. I know the Autodesk people
are restricted in what they can publicly say so if you want, feel free to
e-mail me privately.
