Hi There,
I would like to ask about grading for gore area between main road and Semi Directional Ramp.
For Main Road i have a profile and superelevation.
For Semi Directional Ramp i have just known superelevation and i would like to make a grading for the connection between the Main Road and Semi Directional Ramp ( For Gore Area ).
As you know i have to respect the elevation for the connection between Main Road and Semi Directional Ramp ( Broken Bake line elevation as shown in attached file ).
By traditional ways it takes many days (trial and error).
So, is there any way with Civil 3D Subassembly or other way to solve this issue in less time.

I'm very appreciate for your advice.

Thank you.

A quick study of your diagram suggest that one build a DUMMY corridor along the Ramp alignment.
Use the super-elevation information that is know to construct the profile, and push a simple assembly that will perform superelevation down that alignment.
Create a Top Surface from the Dummy Corridor
In your Design Profiles include the Surface from the Dummy, and use this as your target profile for the outside lane of the Lane Broke Back sub assembly to follow.
If I understand the design question.
