Hi there c.poupin

I was reading this post and noted this solves a problem similar to mine.
I’m not an advanced python user, so this script is a bit complicated for me.
I have a similar problem, only I need to highlight just one element whose “Id” I already know.
Could you help me: Which part of this python script can I take in order to solve this?

Hi,
here an example

import clr
import System
from System.Collections.Generic import List
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *

clr.AddReference("RevitAPIUI")
from  Autodesk.Revit.UI.Selection import *

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

elemId = IN[0]
if isinstance(elemId, (int, System.Int32, System.Int64)):
	uidoc.Selection.SetElementIds(List[ElementId]([ElementId(elemId)]))
elif isinstance(elemIdInteger, ElementId):
	uidoc.Selection.SetElementIds(List[ElementId]([elemId]))
else:
	pass
OUT = elemId
