What does the Top Indicator and Bottom Indicator do? I can't seem to get these settings do anything. See attached.

They actually were created for Revit Structure. I have gotten them to work when putting an elevation height tag on a beam that I placed, as well as on a beam in a linked structural model.

Works for walls, too (in plan). What a find!
