Just went to grab them from my USB thumb drive and it is corrupted, I might have a copy on my work computer that I can get monday, otherwise I can do another run thru halls and just get the locs for the most north, south, east and west points of each map. I used the tool here
http://www.eq2interface.com/forums/showthread.php?t=963 to calc them for halls and I did the calculations manually for lab (hadn't found the tool yet on the site).
My map zone is the same as the lab zone in that they have the same ioplan. However, Halls of Fate zones into one section of the map (what I labelled as map 0), from inside the building on the middle island in bonemire, and Lab zones into the map 3 from on top of the same building. The room where halls of fate finishes (southern most round room on my map 2) is the same room as where lab starts (it has a height of -71.78). Depending on the instance you are in, one door in that shared room is unlocked and the other is locked, you can't actually transition from my maps to ogrebears in the same instance. Not sure if there is any xml codes that will allow you to show the exact same room on different maps depending on which instance you are in, otherwise the altitude change of -72 is the only way I could see to seperate them. All of my map 2 is just above that alltitude and labs goes down stairs as soon as you leave the entry room
I made an adjustment to the min max heights on the 2 transitions and a minor change to the alignment once I re visited halls, edited my prior post.
