You can tell by clicking the building shell tab then the 3-D Geometry Sub-tab while in the Detail Interface. Then hold the Control and right click moving the mouse toward you until you zoom inside the building. Even if you set up the wizard with 3 DWG floorplans and designated this zone as a 2+ space you still may see floors in your model of the atrium. You have to tell E-quest that this zone is a direct return and no a plenum! We had to settle for this as we couldn't get them to go away and the numbers for electrical lighting made sense. Since you are looking at HVAC calcs your answer may not make sense. Changing the ceiling height in the detailed interface speed sheet should force it to read correctly although I have doubts as to the programs ability to let air mix into adjacent spaces from the numerous openings to the atrium space thru wide open doors and over railing partitions. Anyone else have any trick up there sleeve? ? ? Lars, can you also explain you interpolating process for your slanted roof.<br>

<div>
<div><font size="2" face="Arial"><span>eQuesters,</span></font></div>
<div><font size="2" face="Arial"><span></span></font> </div>
<div><font size="2" face="Arial"><span> I
have a 3-story atrium that is shaped differently on each of the three
stories. Accordingly, I have provided the 3-bazillion polygons necessary
to denote the various interior and exterior wall and floor segments that form
the envelope of this atrium. So as to conform to eQuest's required input
data structure, I defined the atrium, itself, as belonging only to the 1st
floor. Accordingly, I will define the space height as the sum of the three
stories heights (interpolating for the slanted roof atop the 3rd story).
When the HVAC load calcs are performed by eQuest, will they correctly reflect
the actual volume of the irregular geometry that I constructed or will it
simplistically multiply the stated space height by the area of the polygon
defining the bottom of this space?</span></font></div>

Thanks, anyone, in advance, for your helpful answer/insight.</span></font></div>
