The extreme slope and curves of the Enterprise D was always problematic. The sets were never able to fully depict the shape of the ship and in fact often contradicted the model.
1) Picard's Ready Room has that single vertical window that he occasionally stares out of. However the model is all curves. There is no flat section on the bridge module.
2) The shuttle bays in the neck clearly have sloped walls yet the standing set had doors that rose straight up. (I never understood why they did that anyway since all they needed to do was give the wall with the door a slight slope).
3) The windows on the crew quarters were never big enough for the rooms. They should have gone from floor to ceiling and been at a sharper angle (or been on the ceiling).
