Permit-set floors stop at the wall

An architect's permit set draws most walls as two lines with an insulation pattern between them. We used to read the inside of those walls as floor. That made rooms a little too big, and sometimes a lot too big: a bedroom took the hallway on the other side of its wall, and a bathroom took a corner of the shower next door.

Now the wall is the wall. Floors are measured to the face of the wall, and a room never runs through one.

What you'll see

• More floors arrive as measured numbers. A bedroom that used to be offered because it looked 25% too big now measures the same on the enlarged plan as on the overall plan, and lands.
• Shower floors on the enlarged plans. Each bathroom's shower is found from the drawing, and its floor is offered on its own.
• A reason on every floor that needs a look. If the enlarged plan cuts a room off at the edge of its drawing, the overall plan's number is offered instead. If a floor runs open into the next room, the note names the room. If it runs into the shower because no curb is drawn, the note tells you how much of it is shower.
• Rooms whose names are printed on two lines — like a master bath labelled "MASTER" over "BATH" with no room number — are now found on the overall plan too, so they get measured on both plans.

What it won't do

• It won't split a room along a grid line. Long reference lines that run straight across the house and through its walls are ignored.
• It doesn't change your numbers. A floor you typed in yourself is never overwritten.
