When working in SU2013 I can see use the "Info Tool" to verify that a ceiling in the first floor corresponds to the interior floor on the second floor. However once I open in TRNBUILD all of the adjacent ceilings become undefined. I manually opened the IDF file, and could not see anything strange.</div><div><br></div><div>I have attached the IDF file. Please let me know what I may be doing wrong or if there is some kind of work around. I would prefer to not use a manual override and loose the ability to make additional edits with SU2013.</div><div><br></div><div>The building consists of 3 floors, and 4 zones per floor. The zone nomenclature is F = Floor, the first number is the floor #, and the second number the zone number. For example F21 is on top of F11.</div><div><br></div><div>Thank you,</div><div><br></div><div>Aaron Danenberg<br>
