How to retrieve the description of all Revit Built-In Parameters?

Hi Guys,
I like to export all built-in Parameters, with the BiP Name, ElementID, and ParameterName to an Excel file (works already with the Node Document.BuiltInParameter from Clockwork). I want additionally to export the description of the Parameter.

Do I need to use somehow Description Property ? And how do I need to adjust the Python Code? Thanks :blush:

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

bips = System.Enum.GetValues(BuiltInParameter)
pdata = list()
for bip in bips:
	try:
		pdata.append((bip,ElementId(bip),LabelUtils.GetLabelFor(bip)))
	except:
		pass
OUT = pdata

The Description property you linked is for an ExternalDefinintion which is related to shared parameters, not builtin parameters. It doesn’t appear that (internal) Definitions have a Description property.
