Autodesk.Civil.DynamoNodes.PipeNetworks.Structure

Autodesk.Civil.DynamoNodes.PipeNetworks.Structure is the object type of structure in CivilDynamo
Need to Access the Autodesk.Civil. DatabaseServices.Structure.SurfaceElevationAtInsertionPoint property through creating a Zero touch node in using C#.

But while creating a method PipeNetworks.Structure is not in Autodesk.Civil.DynamoNodes dll file
Is there any way to make a method with input Autodesk.Civil.DynamoNodes.PipeNetworks.Structure
and returning the value Autodesk.Civil. DatabaseServices.Structure.SurfaceElevationAtInsertionPoint with data type double.
