Unhandled exception when using the cdoc.Styles.SurfaceStyles property in Dynamo for Civil 3D 2022 and 2023

[Snofres]

Issue Description

Please fill in the following information to help us reproduce the issue: I can't call a surface style with it's name or by element index in list in cdoc.Styles.SurfaceStyles when using Python Script. This produces an unhandled exception and error message in the Python node. The drawing contains a Surface Style with name "Standard", but I can't call this in the Python Node in Dynamo, neither by name "Standard" or by index, e.g. styleId = cdoc.Styles.SurfaceStyles[3]. Creating a TIN-surface with e.g. surfaceId = TinSurface.Create(surfaceName, styleName) produces the same error, when styleName is an existing style, e.g "Standard" or cdoc.Styles.SurfaceStyles[x]. Creating a TIN-surface with this method is successfull when a new surface style is created in the same script, e.g with styleId = cdoc.Styles.SurfaceStyles.Add("example style")

Dynamo version

Dynamo: 2.15.1.6076

Operating system

OS: Microsoft Windows NT 10.0.19044.0

What did you do?

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.

adoc = Application.DocumentManager.MdiActiveDocument editor = adoc.Editor styleId=[] with adoc.LockDocument(): with adoc.Database as db:

    with db.TransactionManager.StartTransaction() as t:
        cdoc = CivilApplication.ActiveDocument
        # Select a Surface style
        #styleId = cdoc.Styles.SurfaceStyles.Contains("Standard")
        styleId = cdoc.Styles.SurfaceStyles["Standard"]
        #styleId = cdoc.Styles.SurfaceStyles[0]
        t.Commit()
        pass

Assign your output to the OUT variable.

OUT = styleId

What did you expect to see?

I exected the node to output the Surface Style

What did you see instead?

typeerror no method matches given arguments for OnExit. Unhandled exeption:

What packages or external references (if any) were used?

None

Updated with further info.

It's obviously a known issue for Python.Net that it doensn't handle collection[index]. This thread shows a solution: https://forum.dynamobim.com/t/civil3d-api-python3-syntax-error/79426

As a workaround this syntax can be used instead: styleId = cdoc.Styles.SurfaceStyles.get_Item("Standard")
