Zone global surface

[Anonymous]

I'm looking to obtain from zones an all around external surface, not depending from walls, doors, windows, etc... but only from the volume form, with cuts, boolean, ecc... I tried with ROOM_BOUNDARY_SURF but it seems not give me entry surface... can someone tell me if and how I can calculate this value?
Simply the surface which contains the volume...
