I wrote the below, decided to search another thread, found the answer, and now I'm just disappointed, again. You can't use the auto text label to label a zone, unless the zone room layer is turned on, which means you can't label zones in similar scales if you need the text to appear in different places.
Great job Archicad.
So in imperial archicad there are issues with zone tags and their scale sensitivity I decided to use a label with auto text. I tagged every room (I tagged a light fixture in the room specifically, in the RCP), arranged the labels, and then realized I wanted them on a different layer.
I assume the layer change was the trigger, but that is not an undoable option. All of these tags now have their auto text displayed, and not the zone name and number as it was. (IE #zonename#zonenumber instead of 'Office 002.' Is there any way to correct this? Or reassociate them?
