Need help with Python - FillPatternElement

DesignScript
1

Hello!
I have a problem with my script Python. I need to collect the solid pattern to apply it in a view. But I have an error, and I don’t see where it’s come from.
I find this code on different forum:
patternsList = FilteredElementCollector(doc).OfClass(FillPatternElement)
solidPatternID = 0
for p in patterns :
pat = p.GetFillPattern()
if pat.IsSolidFill == True:
solidPatternID = p.Id

But Dynamo tell me:
“Avertissement:IronPythonEvaluator.EvaluateIronPythonScript l’opération a échoué.
Traceback (most recent call last):
File “”, line 73, in
Exception: Input type(Revit.Elements.FillPatternElement) is not a recognized Revit API type
Parameter name: type”

Do you have an idea to resolve that ?
Thank you for your help
PS: Sorry for my bad english (it’s not easy for me to explain my problem with a different language)

@Melanie_V ,

can you paste your code ?

import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')

from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

#Preparing input from dynamo to revit
element = UnwrapElement(IN[0])

#Do some action in a Transaction
TransactionManager.Instance.EnsureInTransaction(doc)

TransactionManager.Instance.TransactionTaskDone()

OUT = element

Thanks for your answer.
There is my code :

	else :

It’s possible that FillPatterns are not a valid class for the FEC. You can always get this list in Dynamo using Element Classes and All Elements of Class.
