I am attempting to model a Multi-Level space like atrium with eQuest. In the
eQuest DD Wizard (zone names and characteristics), it is possible to define
the zone as it is "open to below". However, if we delete the ceiling of the
first floor in the detailed mode, the results will be different from the
previous scenario. I was wondering which one of these two is the correct
method of modeling the Multi-Level spaces.

Thanks,
