Civil 3d python node


What is a proper way to invite Civil 3d objects and existing Civil 3d nodes in python script ?
Revit example from primer:

import clr
from Autodesk.DesignScript.Geometry import *

# Import RevitNodes
import Revit

# Import Revit elements
from Revit.Elements import *

# Import DocumentManager
import RevitServices
from RevitServices.Persistence import DocumentManager

import System

I found this on primer for Revit, is it similar way for Civil 3d ?
Also is there a special line in command to “unwrap” entering elements ?

TransactionManager.Istance.EnsureInTransaction(doc) - line from Revit python script, does same go for civil 3d ?

If you could point me to a place where i could learn a bit more about that would be also very helpful. I am new to python and dynamo.

Thank you for your time

What i would like to achieve with dynamo is to select a corridor link at a station convert it to a feature line and create a new corridor from that feature line (assign targets also). Don’t know if that is possible…
