<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Hi Danny – here’s a fuller answer for everyone’s benefit. I had this half-typed up from some time ago, and your query reminded me to finish the job… hope it
makes sense!</span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Changing floor-to-floor height in detailed is doable, even intuitive once you get more familiar with how inputs’ defaults are derived by going up the component
tree. It is *<b>not</b>* as quick as wizard mode however. </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">I would advise using the eQuest interface and not directly edit the INP. It’s easier, and you get a visual confirmation with the 3D view of the effects while
you edit which saves time while you’re in a state of learning. One can technically accomplish all of this faster by editing the INP directly, but only after becoming intimate with how the inputs/defaults are interrelated … most easily learned using the eQuest
front-end. </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Common advice for anyone learning detailed mode geometry edits: I’d strongly advise saving and proceeding with a separate copy of your project so you can easily
restart, just in case. </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></div>
<div class="yiv1187985509MsoListParagraph"><span style="color: rgb(31, 73, 125); font-family: Symbol; font-size: 11pt;"><span>·<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">First: observe the
<u>default</u> (green inputs) flr-to-clg height of all spaces is the flr-to-clg input for the parent floor (I’m calling it a shell hereafter). Double click the shell to edit flr-to clg, and the default entries for the child spaces will dynamically adjust.</span></div>
<div class="yiv1187985509MsoListParagraph"><span style="color: rgb(31, 73, 125); font-family: Symbol; font-size: 11pt;"><span>·<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">Second: the
<u>default</u> height of wizard-generated plenum spaces depends on whether they are “unconditioned” or “plenum” space types coming out of the wizards (which in turn is based on whether you selected a ducted return air path in the wizards). </span></div>
<div style="margin-left: 1in;" class="yiv1187985509MsoListParagraph">
<span style="color: rgb(31, 73, 125); font-size: 11pt;"><span>o<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">If your plenums are the “plenum” space type, the default space height is, intuitively, the difference between the parent shell’s flr-to-flr and flr-to-clg
inputs. The Z-coordinate for the plenum space also references the parent flr-to-clg. Everything updates dynamically when you edit the shell inputs.</span></div>
<div style="margin-left: 1in;" class="yiv1187985509MsoListParagraph">
<span style="color: rgb(31, 73, 125); font-size: 11pt;"><span>o<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">If “unconditioned,” the default plenum height would be the parent shell’s flr-to-clg. This would be wrong in most cases, so the program instead defines
(red inputs) space heights and z-coordinates for plenums derived from your wizard flr-to-clg and flr-to-flr inputs.
</span></div>
<div class="yiv1187985509MsoListParagraph"><span style="color: rgb(31, 73, 125); font-family: Symbol; font-size: 11pt;"><span>·<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">Based on the above mechanics: Editing only the shell flr-to-flr input (as you described doing to your INP file) would have little zero effect on
your spaces if the plenums were generated as the “unconditioned” space type.
</span></div>
<div class="yiv1187985509MsoListParagraph"><span style="color: rgb(31, 73, 125); font-family: Symbol; font-size: 11pt;"><span>·<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">If your plenums are “unconditioned,” what you want to do is revise your shell flr-to-clg as necessary to the height you want for the non-plenum spaces,
then manually revise your plenum spaces’ flr-to-clg and Z-coordinate inputs (most easily done in spreadsheet view).</span></div>
<div class="yiv1187985509MsoListParagraph"><span style="color: rgb(31, 73, 125); font-family: Symbol; font-size: 11pt;"><span>·<span>
</span></span></span><span style="color: rgb(31, 73, 125); font-size: 11pt;">Finally: If you have multiple shells stacked on top of each other, you will also want to review the Z-coordinates for each shell to accommodate the
new floor to floor heights.</span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></div>
<div class="yiv1187985509MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">You’ll notice coming out of the wizards, all walls and other child surfaces reference their parent space geometries, so surfaces should automatically adjust
to the new heights as you make the edits above. </span></div>
