Every walled piece in the export is found, a basement or an outbuilding included, and named from the title PlanUp printed over it. Floors that share a wall with the ground floor are set level with it; the rest stay where PlanUp drew them. Any floor can be dragged on the preview and put down anywhere, and it settles onto another floor's wall as it comes level; hold Alt to place it freely. The arrows move it a millimetre at a time. "Move earlier" and "Move later" change which floor comes first across the sheet. The arrows move a floor a millimetre at a time if one still sits out.

With guide lines on, a line runs out from the outer walls of every floor, and turns black where the walls of two floors are level. They are never saved into the JPEG.
