<p class="MsoNormal"><span style="color:#595959">My understanding of defining the vertices is that the way they line up only affects how the wall constructions are defined, and shouldn’t result in an error. For instance, for zone boundaries defined near an
exterior wall where the vertices don’t line up exactly, eQUEST may define them as an interior wall, or possibly an exterior wall with no windows (I haven’t taken the time to discern what the ruleset is for that). Internal zones that don’t line up perfectly
are usually defined as adiabatic rather than as an interior wall construction, but the space and zones themselves don’t really care if they line up or even overlap. For my purposes, I took the time to do the exterior walls correctly, but it’s not worth the
additional time to get the interior walls perfect (this isn’t for LEED or anything quite to that level of detail) for every single space.

<p class="MsoNormal"><span style="color:#595959">As an example, you can set up and run a brief model on a building like below, and it will fully simulate without errors, despite obvious overlapping floorspaces and walls that don’t line up.

<p class="MsoNormal"><span style="color:#595959">Normally I take the time to line things up well, so I could be wrong on this. Am I misunderstanding what you guys are trying to say, or (more importantly) am I missing something wrong with this approach?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#595959">I tried Robby’s suggestion - I duplicated that shell, and on one copy I deleted the north zones, and the other I deleted the south zones, and the errors have disappeared.

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:13.5pt">I would say some of your vertices are not lining up. Even visually I can see a few potential problem points for you. They have to be exact. Nothing can overlap nor can there
be any gaps. eQuest is very picky, you pretty much have to be exact to 3 decimal places. It may sound like a lot of work but I would print out your CAD plan and mark your points on it. When I do my perimeter I add extra points on the exterior walls where
the zones intersect. It gives you something to snap to</span> <span style="font-size:13.5pt">
when you are defining your zones later. When defining your zone polygons you can also directly edit the number if you can't get the point to snap exactly. The only snap I use is the CAD drawing. One other thing I do is make an eQuest layer on the CAD drawing
and simplify the plan to the perimeter and the zones. It makes it easier in the long run to keep track of all the vertices. There are too many potential places to snap to on an architectural drawing.<br>

<p class="MsoNormal"><span style="color:#595959">This one has me stumped, and it looks like it’s been an issue before, so I’m hoping someone has an idea. I was building a model in the wizard and went to save-as before something got screwy, and it appeared I
was too late. I got an error for multiple zones that read “MULTIPLIER in <i>XXXzone</i> has Expression Evaluation Error: Invalid BDL reference”, followed up by a bunch of zone errors stating that they were “referenced but not defined”. I did some searching
and came up with a few hits, but no solutions (that I could see). I bit the bullet and went back and tried to rezone it from my last save, and while the error seems to occur for different zones, I still got it. I went through and tried to purge out some AHU’s
and spaces that may have pushed me up against some limit I’m not aware of, but nothing’s helped so far.</span><o:p></o:p></p>
