And if you are unsatisfied by those variations, any shape can be turned into a wall hole, or more simply, a complex profile that cuts a shape from a wall.
I did eventually make a complex profile for it, however, turning the odd shape windows that Barry (thank you Barry) is showing us, into an empty opening, makes the whole in the wall going back to a rectangular shape (linked to the 'empty window' library part of course.)
