Wall composite between roofs

KersK0 — Fri, 02 Aug 2024 02:50:02 GMT

Hello everybody,

I have a problem to correctly model my composite wall between two roofs but i don't know how to do it.
On the outside face I want my wood cladding material between the two roofs but not under the lower roof, and if possible insulation and plaster like the lower wall.
On the inside face I want my wall to be insulation and plaster.
I assume I have to do it with two walls (because there are 2 differents composites) but I don't know in which order I have to use SEO or Merge function.

Thanks in advance.

Operating system used: Windows

If that is one wall for internal and external skins then SEO with upwards extrusion to the upper roofs.

Then SEO with downward extrusion to the lower roof.

That should do it.

Hello Barry,

thank you for your reply. The problem is that I can't have the layers I want if I make a SEO.
The upper wall is composed of :

- EXT : wood cladding, concrete, insulation, plaster INT

The lower wall is composed of :

- EXT : plaster, insulation, concrete, insulation, plaster INT

If I make a SEO on the upper wall, the extrusion will "cut" the wood cladding material.

I hope I am clear enough to understand.

Because you want the lower internal plaster to continue up higher than the top of the lower wall, you will have to create a new wall composite for just the plaster and insulation and trim that to the lower roof.

Or you can create a complex profile with modifiers for the lower wall and you can stretch the inner plaster and insulation skins up - this will work with a flat ceiling, but it can't rake the height.

Problem is I am not if the wall above, although trimmed at the base will still interact with this plaster wall and automatically trim it away as if the timber wall skin was still there.

If it still does not work with SEO then maybe the Connect > Trim to Roof will work better?

I am not sure without trying to set up the same scenario.

Or you may need to create more composite walls.

Lower wall - plaster, grey insulation, concrete, grey insulation, plaster

Middle wall - plaster, grey insulation, concrete, (same as lower wall), yellow insulation, plaster (same as upper wall.

Upper wall - wood cladding, concrete, concrete (2 skins?), yellow insulation, plaster.

Lower wall up to slab height on the right as it is now.

Middle wall from there up to lower roof height SEO to lower roof.

Upper wall from middle wall top height to upper roof - SEO base to lower roof and top to upper roofs.

Again if you have a raking ceiling in the lower left room, then trim to roof might work better than SEO, because I think with SEO the wall trimmed away acts as if it is still there and may still trim other walls.

I am not sure if the connect to roof trim works a bit differently or not.

If you still have trouble, place an all storey marquee around that area.

View it in 3D window.

Select it all and File menu > External Content > Save Selection as Module.

Then attach the MOD file here (you will need to zip it first - ,ZIP not .RAR please).

Then I will try to have a look - it will save me trying to re-create your situation.

Barry.

I finally found a solution thanks to you.

My upper wall is trimmed to upper roof and SEO downward with the lower roof.
I apply upward SEO on the lower wall with the slab, upper wall and lower roof.

I lowered the priority on the insulation/plaster of the lower wall because otherwise there was a hole in the slab.

I don't know if this is the best way to do it, because there's a lot of SEO.

I attached the mod file here anyway.

Thanks again.

Looks great.

If it works, it is good - that's what I say.

Don't use the Connect > Trim to Roof option as that uses the roof trimming body.

When you keep the wall above the lower roof, you will lose half of the inside width because it is outside of the roof plane.
