Click an edge to cycle wall → door → archway → window → empty. Click a cell's middle to cycle a diagonal wall / → \ → none. Drag to repeat the last state. Shift-click clears. For an angled exterior wall, clear the two straight segments and drop a diagonal in the corner cell. Each room's number sits on its lowest-load cell — that room's commanding spot.
