Interior elevations are where a tile job's wall sizes live — the run of the wall, how high the tile goes — and on a package we looked at recently, seven of eight sheets read perfectly and then went nowhere.
The reason was dull: the sheets were titled Primary Bathroom, Bath One, Bath Two, and the rooms the tile schedule had built were called Maddox's Bath and Jax's Bathroom. Nothing matched, so nothing landed, and nobody was told. That's fixed, in four ways.
A sheet whose title doesn't match any of your rooms now gets a room. If the elevations draw a primary bath and the schedule never listed one, the primary bath shows up with everything the sheet prints for it. Three sheets drawing the same room land on one room, not three.
A sheet that could be two of your rooms asks you which. With the sheet a tap away and its figures listed, so you can usually tell from the numbers:
Which room do these elevations draw? — "Guest Bath" · Floor — 55 sq ft · Shower walls — 62 sq ft
(Since changed. From September 22, a sheet for a room your schedule and plans don't cover joins the more rooms — add any list instead of becoming a room on its own. From September 24, a sheet Biddy can't place goes on one check with every room in your bid to pick from, instead of this one-sheet question. See "Wall sheets Biddy cannot place are asked about, all at once".)
A wall the schedule never mentioned still gets offered. A tile schedule is a list of products; an elevation is a drawing of the work. If a sheet draws and dimensions a shower wall the schedule didn't list, that wall now shows up on the room with its size offered. Offered, not priced — it waits for your tap like every other reading off a drawing.
Tile heights come straight off the sheet. This is the one number nothing else in a package tells us, so everywhere else we fall back to the usual heights and ask you to confirm them. Where an elevation prints the height, that's what the surface gets and you don't get asked. Heights you've set yourself always win.
Two smaller things came along with it. Room notes now mention what the elevations gave the room, marked as a suggestion so you can tell at a glance what came off the schedule and what came off a drawing. And when a package names one room two ways — Back Kitchen on the floor plan, Back Kitchen/Pantry on the spec sheet — you get one room instead of two, as long as neither has any work on it yet.
