Once you have outlined a room in CADinput how do you turn one of the walls into a 'blank; so that ist represents an open space?
I followed the instructions on the help file but the section box is says opens up does not in my version of HEVACOMP.
Chris - this is not possible to accomplish with the program. If there is no surface between the 'room' and the 'office' then they should be drawn as one continuous space. There is no facility to change the parameters of the surface to make the room open to the office.
If you are attempting to join the space together with a zero height partition, this is a facility that is only used when defining atrium spaces for the Simulation software and is not considered by the steady state calculations in Design Database. Any such surface will still appear in CAD Input as a solid surface, even under these circumstances.Regards,

Chris, to extend on Duncan's answer you should consider the following. Steady State calcs such as CIBSE will consider the temp on the other side of a partition. When using CAD Input this will default to the design condition specified for the adjacent room as it is assumed that condition will be met. If the design condition is the same for this sub room and the main office then there would be no net gain\loss across the partition anyway but the mass of the partition may have some effect on the overall result. As such I'd recommend creating a new 1mm thick partition type of lightweight material and set the partition to that type. If you're wanting to see something more dynamic due to differing design temps then Simulation would be needed as Duncan mentioned.
