We need to be able to dimension a room width by length. Let the tag allow the user to pick left - right, then top - bottom (in plan view) to determine what walls or entities should be used as the measurements.
Also, a ceiling ht needs to be added for use with standard flat ceilings, or incorporate some intelligence into any tray ceiling so that label can call out as "X-X Tray Clg". If the ceiling is sloping it would call it out as "Vaulted Clg".
The folks at Revit should be able to figure this out. Having to manually to go through the process of labeling room sizes and ceiling heights is redonkulous. I have a lisp routine that does this in 2D cad that I created back in 1994 for pete's sake. Can't we do this is TWO THOUSAND SEVENTEEN?! lol.
That's all I have to say about that.
