Does not return the outdated dynamo surface to the tool space

Good morning. I am generating a script in dynamo that generates a gap to a superificie that comes from civil 3d (I have already achieved this), but it does not return me the superificie calculated in dynamo to civil 3d.

PRUEBA SURFACE CIVIL 3D.dyn (16.4 KB) prueba superifice dynamo.dwg (1.1 MB)

@CARodriguezA in your definition there are no nodes to create the objects back in Civil 3D. If you want a TIN Surface from Dynamo, you need to create a COGO Point Group first.
