https://community.graphisoft.com/t5/Collaboration-with-other/how-to-relate-the-wall-surface-to-the-zone/m-p/246798#M32092 I don't know if this is a bug or this is how the program works and it is a limitation.<BR /> The "Related Zone" field is actually generated for the Wall, not the Surface of the Wall.<BR /> So, if I understand it correctly, when you schedule the "Related Zone" field for a Surface, it will list the Related Zone of the Wall the Surface is part of. This is why both Zones are listed for both Surfaces.<BR /> <BR /> I am not completely sure about this so I will forward this to GRAPHISOFT. Let us see what they say about it.
