<p>Suggest reverse engineering...define your objective in eQuest (starting with the lower-leftmost vertex for all polygons) and compare the resulting inp file to yours. Also take a close look at the DOE2.2 documentation, wherein the coordinate system is detailed. <br>
</p><p>Suspected root cause issue is the disconnect going from the eQuest Floor/Zone editor, where all zone (space) coordinates are entered absolute, to the .inp file where the eQuest stores coordinates of space polygons relative to the floor polygon.</p>
<p>Suggest always starting all polygons with the lower-leftmost vertex, to help make sense of the relative coordinates and azimuths. This habit is one you'll be glad to have acquired, should dissecting inp files become your muse.</p>

I was expecting it to be in "NE" quadrant of the the building's XY plane, but instead it's in the "SW" quadrant, as if it had been rotated 180 degrees about the building coordinate system's z-axis. Puzzlingly, the SPACE and FLOOR objects appear where I would expect them to -- in the building's "NE" quadrant. <br>
<br>Clearly I'm misunderstanding something about how POLYGON objects are to be positioned. If anyone could help me to understand what I've got wrong, I would greatly appreciate it. <br><br>Many thanks,<br><br>Josh<br>
