When linking Zones to Rooms, the key value is read from dRofus and then written in to ArchiCAD (unless the ArchiCAD parameter is read-only or the dRofus parameter is emptyis empty - in which case the key value is read from ArchiCAD and then written in to dRofus). The following is an example of a Zone <-> Room Configuration where the Room ID is used as the key, and the values against the Room ID attribute in dRofus gets injected in to a parameter called UserData under InternalData in ArchiCAD, after which the link between the dRofus Rooms and ArchiCAD Zones will then be maintained:
