Sky Light punch through underlying ceiling

[Liam]

I have a trussed roof design where the angle of the roof slope (34 deg) is different from the slope of the underlying ceiling (19 deg) (picture 1).
There's an approx 2 foot distance between where the skylight is cut into the roof and where the corresponding cut needs to be made in the ceiling below.

I have solved this problem by just placing the skylight on the roof and then using the frame depth parameter to create a 2 foot 6inch light "tunnel", then cutting a hole in the underlying ceiling at the right spot.
Is this the recommended way or is there a better approach?

Since the angle of the roof is different from the ceiling, when the skylight emerges through the ceiling, it is of course not flush with the ceiling as shown in the picture.
Is there a way to change the angle of the skylight frame at the bottom to achieve a flush look?

Thanks. Liam.

I did something like this a few years ago (2006)...tho ceiling was level...see attached image

as I remember I made cutout/opening in the ceiling, placed a skylight on the roof normally, then added a floor/location near base of the ceiling, built 4 walls/room around the opening (no floor or ceiling) and played with walls to align along bottom (actual room ceiling to which skylight lets in light) and top (underside of roof/skylight).

I left the bottom open but you could add a frame and a "glass" pane or traslucent plastic etc.

It looked good and transmitted light thru as expected. Work zoomed close-up to ensure good alignments at joints


You could use imported shapes for the internals/walls if you know the sizes and angles...easy to make in TFP or SketchUp.
