How do I set my room’s size?

Choose Room dimensions and type the width and length, or pick a preset from Small (30 by 25 feet) to Grand (120 by 80 feet). Once the room has walls, select it in the wall editor and use Set size.

Set size takes the two numbers in either order. The longer one runs along the room’s longer side, and a turn button lays it the other way. It is one change, so one undo takes it back.

Sizes work in feet or metres. See feet or metres.
