Zones have to touch the walls the doors and windows are in to recognise those doors and windows as being to or from that zone. If you are looking to extend the zone in to the reveal there is an option within calculation settings to allow zones to fill in to the door reveal dependent on the reveal depth.

yes! However, Archie does not work even if the reference line and the zone area overlap. It looks like it was made based on the wall only. The presence of either to or from is related, but It's not okay to not have both.
Aki can't do it, so I guess I'll have to change the wall in another way. Thank you always for your replies.
