Is a Revit Part divided?

Hello, When examining a list of Revit Parts, if the Part is divided, the original part and the divided parts are both in that list. Element.Parameters doesn’t seem to show a property indicating the item is the original part or the parts created by the division of that original. Any suggestions on determining if a part is divided? Ultimately I need a list of: - Undivided Parts - No Parts that nave been divided, but include the subdivided Parts Thank you for your time.
