Hi Everybody.
I´m trying to create a building pad with python node.
pad = BuildingPad.Create(doc,typeId,levelId,loop)

I’m not sure about this error.

Python Script got crash:

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):

TypeError: expected Curve, got CurveLoop

#inputs
level = UnwrapElement(IN[0])
padType = UnwrapElement(IN[1])
curves = IN[2]

#necessary ID’s
levelId = level.Id
typeId = padType.Id

#creating CurveLoop
loop = CurveLoop()
for c in curves:
loop.Append(c.ToRevitType())

#get the document
doc = DocumentManager.Instance.CurrentDBDocument

#use safe transaction with Revit
TransactionManager.Instance.EnsureInTransaction(doc)

#creating pad
loops = [loop]
pad = BuildingPad.Create(doc,typeId,levelId,loop)

#Finish transaction with task done
TransactionManager.Instance.TransactionTaskDone()

OUT = pad

That method requires a .NET list of curve loops and in IronPython you can instantiate such a list using the following syntax:

loops = List[CurveLoop]()
loops.Add(loop)
pad = BuildingPad.Create(doc,typeId,levelId,loops)
