I have a floor slab and a roof slab in which I have to place a window on the roof that would face outside. The problem is that when I use the command "hole in floor slab" it always generates the hole perpendicular to the ground, and I need it perpendicular to the slab itself.

Is there any way to do it?

I attach an image so you can see what I mean. The thick pixelated lines are where I need the window opening to go in the floor slab, and the thin ones are the way Allplan is making them.
