I have an issue with the skylight-window

Kamelite — Tue, 23 May 2023 12:29:41 GMT

How can I solve the problem marked With green? I know why it happens, but I don't know how to work around it. The reason it happens is because the roof is actually two separate roofs, the insulated part is one roof, and the rest is another roof. The reason for doing it that way you can see in the red ring. I don't know of any other way of achieving that effect, apart from a very tricky SEO maybe...

Any Bright ones have any ideas how to solve it?

If you mean cutting a hole in the insulation then you will have to cut that hole manually because you have used 2 separate roofs.
The hole can have splayed edges too.

Otherwise as you suggested you will need to use one composite roof so the hole will be automatic and you will have to do something else to fix your eaves.

Hello,
try to use one roof for centilever part and one for the remaining roof plane.
It works for me.

I would repeat what Barry said. I have done this both ways. The SEO is not that difficult as you can use another piece of roof to cut away what you don't want on the overhang. The SEO option is perhaps the best in terms of making changes later if you had to move the skylight as it would not involve repositioning the hole in the lower roof as well.

Cheers,

Did this recently, was not difficult and remained easy to manage, whereas Ilder's method does not work with roof accessories (coverings).

Hm, that actually makes sense 🙂

That pops the question: How do I go ahead and make piece of roof that makes the operator in this particular SEO? Is it possible to create a roof that contains only the part from, say, the Reference line and further out, or do I have to do an SEO one the roof first, to remove everything inside the SEO, and then perform the SEO on my primary roof?

.Thag

What I do is make my SEO easy to see by making it red. Just draw a piece of roof with the appropriate slope and wide enough to include all the area you want to cut and a little extra on the outside and ends. I use a temporary Section view to drag it into the correct position. I then perform the SEO operation either in Section or Plan view.

Of course it is possible to create 2 roofs with one being from the wall reference line out but I would not recommend this as any edits would be more complicated. eg. changing roof slope. Also if you use any kind of a roof cladding add-on this would be a problem.

See attached tiffs. In the SEO'd view I have also used the wall to SEO the roof which would be the case if you were birds-eyeing the rafter. The roof doesn't have the correct composition but should give you the ided. Hope this helps. I see I can't attach more than one image so will post after this.

After SEO operation from both the roof SEO element and the wall.

It's obvious i've missed something.
Using two roofs, one insulated for the inner part, and one not insulated for the outer part, same reference line and stretching contours i don't need to use SEO.
S2art, what does it mean it doesn't function with coverings?

We use Cadimage Coverings (similar to the old roof accessory tool) to model the roofing profile, flashings, spouting etc. If the roof is not one continuous plane right to the edge (i.e. joined at the wall line to another roof plane) the covering will put the spouting in the wrong place, and dealing with that join, while possible, would be a real pain.
