ROOM_... not showing any values

[JGoode]

Hi,

I'm trying to get the following to show a value but I can't seem to work out what they do or why they're not showing values:

ROOM_ROOF_TOP_SURF Surface of zone top where trimmed by a Roof
ROOM_ROOF_BOT_SURF Surface of zone bottom where trimmed by a Roof
ROOM_SLAB_TOP_SURF Surface of zone top where trimmed by a Slab
ROOM_SLAB_BOT_SURF Surface of zone bottom where trimmed by a Slab
ROOM_BEAM_TOP_SURF Surface of zone top where trimmed by a Beam
ROOM_BEAM_BOT_SURF Surface of zone bottom where trimmed by a Beam

Any help is very much appreciated

They are working only if you trim (it been renamed, now it's trim) bottom or top of your zone. If you didn't trip the Zone, their values probably will be zero.
