Situation : I want to create a schedule that counts all instances of the same family in each room.
Thus, I create a schedule and sort with "Family" field, then with "Room:Number" field (it also works with "Room:Comments" if it's typed correctly); and I uncheck "Itemize every instance"
Issue : In a room, if all instances of the same family are from different types, Revit display a blank field, instead of the name of the family. (see attached image)
