Skylights one above the other?

[MarinRacic]

I've attached a photo what I'd like to do in AC, but I get unsatisfactory results when using 8.1 skylights (top- or pivot-hung)...

[MarinRacic]

This is the result I get from AC... Is it possible to modify the way skylights are cut into roofs?

Marin,
The hole that the skylight tool creates in the roof is a normal
roof hole and it's edge angles can be edited by selecting
any hole edge, with the roof tool enabled use the edge angle
pet pallet option to edit the angle.
In this case "Perpendicular" and "Apply to all edges" (of that hole).
HTH,
Peter Devlin

You're not going to be happy with this...

It seems very odd to me, but the cut is adjusted by modifying the roof, not the skylight. (I find it similarly odd that if you select a wall and go to 3D, you get the wall and all inserted doors and windows, but if you insert skylights and select just the roof, then in 3D all you see is the roof. Not consistent. I understand why: skylights are done by an API add-on that cuts holes in the roof and then makes sure that the holes follow the skylight as it is moved. But that doesn't make it make sense.)

Select the roof, then with any tool except arrow (or any tool in 9.0) mercedes down on the edge you want to adjust and use the roof edge button in the pet palette to change the angle of the cut.

Naturally, because this is done by modifying the roof, and not part of the skylight, there is no way to eyedrop/syringe this new hole onto your other skylights... the other edges have to be manually edited.

And worse, if you drag your skylight to a new position, the roof edges revert to the original angles and you have to edit them again. Argh.

And even worse: if you put the skylights in a very low pitch roof (such as 2:12), they may not even cut a hole with OpenGL enabled! (I get a hole if viewed from the top of the roof, and no hole when viewed from the bottom.) If you want square edges, you may have to temporarily switch to the internal engine so that you can adjust the edges, and then switch back to OpenGL.

Hmm. I've lost count of how many workarounds are in this one post!

If you post a wish for consistent behavior in this area, I'll vote for it! 😉

The image posted reminds me very much of the VELUX range?

AFAIK there is a full GDL library of VELUX products - however, I am not aware of whether any of them is a skylight (which they should be). Maybe you should inquire with the local VELUX people, and check the GDL Central?

The problem is the roof edge angle, as Karl explained ...

Karl: thanks for the extensive tip and problem definition! I'll post a poll in the wishes section in a minute so be sure to drop by and vote.


Đorđe: I've downloaded the 2004 Velux library from www.velux.at - they ARE skylights so anyone in the need for a good collection of skylights should stop by and download it.
