Hi Christophe,
I have a schedule that lists these values (nominal width/height, Element ID, Parent ID).
I'm building expression based properties on them and it's rather counterintuitive to switch back and forth a schedule and the property manager window (the schedule shows the evaluated property, but the property manager's editor window not).
It works for "normal" elements like a wall or slab, but not with subelements like a CW panel.
