Skylight cutting roofs and ceiling

[Tom Krowka]

How does one enable skylight to cut through two roofs and a ceiling below with a consistent shaft. Is it possible to do with only a skylight. It cuts a hole through it's own roof, but doesn't seem to project down.
Tried turning on the cutting body, but it doesn't seem to have any effect.
Any easy way to do it without creating a shaft object and using a SEO operation to cut the shaft.

Your roofs and ceiling all need to be just one composite (not possible if the skins are not parallel.
It is like windows in wall - you don't model each wall skin separately.

I am about 90% confident it would be possible to tweak the GDL of the skylight to include a shaft that would cut holes only when an SEO is performed between the skylight and the other roof skins - would still need to be done manually (but I have never really looked at a skylight script so can't be totally confident it would work).
It would be easy to just model the shaft and SEO that - depending on how many you have to do.
