Save as for Civil3D and close document

In Revit, there’s a Dynamo node to save documents, but I couldn’t find a similar node in Civil 3D Dynamo. Does anyone know if there’s a node available with this function?

Same question for the closing a document.

This one is quite simple really…

Thanks that works! There is also a situation were i just want to close the DWG without saving the DWG. When i send the “close” command i get this pop-up. Is there a way to bypass this popup?


I am trying to create a Python node with doc.CloseAndDiscard()

from Autodesk.AutoCAD.DatabaseServices import *
from Autodesk.AutoCAD.Geometry import *

# Import references from Civil3D

from Autodesk.Civil.DatabaseServices import *

def close_dwg_without_saving():
    # Get the active document
    doc = Application.DocumentManager.MdiActiveDocument
    # Check if a document is open
      if doc is not None:
        # Close the current document without saving changes


I am not sure that Dynamo/civil 3D will be stable if you close the active document, as it is required to send/receive commands. This might crash your system on command if it works, so just be ready for that.

if you are working a “new file”…I.e., “Drawing1.dwg” which launches at the start of each session.

This file is unsaved. There is not a way to avoid that pop up while working with a drawing that has not been saved.

so you might need to save it somewhere as a junk file, then the close command would work.
