How can i create Multiple Section View Using Civil 3D Dynamo Python Script?

Hi,

There are some nodes in Camber, Arkance and C3DToolkit packages, but I don’t know their limitations.
Last year I tested section view group creation, but I did not get it to production, so use it with caution.
It should create section view group for every input sample line groups.
It is also made for specific template, so you have to modify style names in the code. As I said it is not complete, not well tested, so bugs may occur, i.e. source selection. (see video)
That said here is the script, you can start your own using this:

# Load the Python Standard and DesignScript Libraries
import sys
import clr

# Add Assemblies for AutoCAD and Civil3D
clr.AddReference('AcMgd')
clr.AddReference('AcCoreMgd')
clr.AddReference('AcDbMgd')
clr.AddReference('AecBaseMgd')
clr.AddReference('AecPropDataMgd')
clr.AddReference('AeccDbMgd')

# Import references from AutoCAD
from Autodesk.AutoCAD.Runtime import *
from Autodesk.AutoCAD.ApplicationServices import *
from Autodesk.AutoCAD.EditorInput import *
from Autodesk.AutoCAD.DatabaseServices import *
from Autodesk.AutoCAD.Geometry import *

# Import references from Civil3D
from Autodesk.Civil.ApplicationServices import *
from Autodesk.Civil.DatabaseServices import *

# The inputs to this node will be stored as a list in the IN variables.
dataEnteringNode = IN

#sample line groups
SLGS = IN[0]
#insertion point
P = IN[1]
#station range, 0 if from start to end
SSin = IN[2]
ESin = IN[3]
#placement type 0 if draft, anything else if production
placement = IN[4]
templatepath = IN[5]
layoutname = IN[6]
