 * Create a rectangle: Snap its cornerpoints with to the corners of the assigned area
 * Offset the rectangle: With the rectangle selected, press Offset, press to turn on copy mode, move your mouse inside the first rectangle so offset knows in which direction to go, and type 0.20, Enter
 * Turn them into a face: Upgrade the first rectangle, upgrade the second rectangle, then select the outer rectangle, CTRL-select the inner rectangle and press Downgrade
 * Create the door opening: Make a 1.00 x 0.50 rectangle, move it to the upper corner of our main wall (press to turn copy mode off).
 * Move the door opening to the right position: Move it 0.10 to the left. We won't put our opening directly on the corner, because it would make the door difficult to open.
 * Subtract the door opening: Select the wall, CTRL-select the door opening, and press downgrade.
