To link your doors or windows to existing zones in the schedule, you need to add 2 parameters and a few lines of code to your objects.
The parameters:

• gs_bOpeningToZone (Boolean)
• ac_zone_on_reveal_side (Integer, and should be hidden)

While gs_bOpeningToZone is a user controlled parameter, where the architect can decide whether the zone is on the opening side of the door/window or not, the other parameter should be set automatically, based on the flipped status of the opening and the value of gs_bOpeningToZone parameter.
This can be done with the following code in parameter script:

if WIDO_REVEAL_SIDE exor not(gs_bOpeningToZone) then
	ac_zone_on_reveal_side = 0
else
	ac_zone_on_reveal_side = 1
endif
parameters ac_zone_on_reveal_side = ac_zone_on_reveal_side
