skylights cutting holes in 2 roof surfaces?

[Anonymous]

I am trying to place some skylights onto a roof made up of two roof objects stacked on top of one another. i'm trying to create scissor trusses. i can't seem to get the skylight to cut through both roofs. i've extended the trimming bodies but that didn't do it and solid element operations aren't permitted. any thoughts?

wildy,
the skylight, like a door or window, will only cut through one surface. You will have to cut a hole in the sloped ceiling. You will also be putting in walls , vertical or sloped from the ceiling to the roof to separate the light shaft from the attic area.
There is a scissor truss in the library, or you can make a custom one using the trussmaker addon

Thanks,
I'll have a look at the truss maker again. i assume the skylight will cut through the scissor truss? if not i'll have to do it the long way around.

No the skylight will only cut a roof surface.
Besides you wouldn't want to cut a truss would you?
Wouldn't you have a truss on each side of the skylight?

HI,

what does it mean that solid element operations are permitted?
Even if the operator element is on the object? (with Glob_Context=43)

I wanted a skylight to cut a model truss that was on layout (but ran through the middle of a wide skylight) as to not show a truss in the skylight view, since the skylight has a girder truss on either side of the skylight in my situation,(with obvious cross girder piece on the high and low end of the skylight).
Since my truss (objective piece) is not the real truss as the truss company supplies, thought it was immaterial that my trusses are not how
the truss mfg will build them anyway.
So I had to seo the piece out.
