UnwrapElement won't work for Dynamo Plane

[y.KWON]

Hello,

I’m tried to create sketch plane with python script in Dyanamo.
I’ve read this article

Set Work Plane

Thanks Einar, I watched the link, I made some changes to your code and now work perfecly! Thank you so much!! here is the final code that I created import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * # Import Element wrapper extension methods clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) # Import geometry conversion extension methods clr.ImportExtensions(Revit.GeometryConversion) # Import DocumentManager and Transactio…

and tried, (below is only part of code)

rPln = UnwrapElement(IN[0])

# Set the reference plane as the sketchplane in the active view in another transaction
TransactionManager.Instance.EnsureInTransaction(doc)
sp = SketchPlane.Create(doc,rPln)
doc.ActiveView.SketchPlane = sp
TransactionManager.Instance.TransactionTaskDone()

by IN[0] a Plane is given, that is created through Dynamo Plane.ByTreePoints.
However, Python Node give me Type error message,

“Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed. Traceback (most recent call last): File “”, line 41, in TypeError: expected Plane, got Plan”

Can somebody tell me, what did I wrong?
