Oh sorry, I was imprecise.

Look here:


I have a few dormers, but no side wall for them. An the walls/sides/whatever have the shape of a triangle, but not a perpendicular one. And I do not know the measures and also I cannot get them from the pane with the view from above. But I see the open dormers in the 3D aerial view. What I meant was, if I could some set points there in order to get the measures.
