Identical to Trim Panel JM9 and Trim Panel Ceiling JM9, except it's a skylight. And since it's a skylight, it can only be rectangular.
(Q: Why don't you give the ceiling version a slope parameter, then we could subtract from roofs and have all the shapes? A: Good idea, but you can only subtract straight down. You would need to subtract in an angled direction. A wish.)
The 'height' is stretchable in 3D. The height is stretchable in plan too, though the plan view is foreshortened. Further, the plan image shows the shape at the bottom of the roof, what you'd want to see in the RCP. But the hole in the roof is displayed as seen from the top; they won't align, don't worry about it.
