This is indeed a little tricky because these elements don’t have a Parameter called name, but instead its a property. Here’s how you can handle it.
Here’s the code that’s inside of Python:

# Import Element wrapper extension methods
import clr
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
# Import RevitAPI
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *
import sys
pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib'
sys.path.append(pyt_path)
#The inputs to this node will be stored as a list in the IN variable.
dataEnteringNode = IN
def ProcessList(_func, _list):
return map( lambda x: ProcessList(_func, x) if type(x)==list else _func(x), _list )
def ProcessParallelLists(_func, *lists):
return map( lambda *xs: ProcessParallelLists(_func, *xs) if all(type(x) is list for x in xs) else _func(*xs), *lists )
def SetName(e, name):
e.Name = name
return e
def Unwrap(item):
return UnwrapElement(item)
if isinstance(IN[0], list):
elements = ProcessList(Unwrap, IN[0])
else:
elements = [Unwrap(IN[0])]
names = IN[1]
try:
errorReport = None
TransactionManager.Instance.EnsureInTransaction(doc)
output = ProcessParallelLists(SetName, elements, names)
TransactionManager.Instance.TransactionTaskDone()
except:
# if error accurs anywhere in the process catch it
import traceback
errorReport = traceback.format_exc()
#Assign your output to the OUT variable
if errorReport == None:
OUT = output
else:
OUT = errorReport
Basically we created a method that will override a Name property on any element.
Cheers!
