Ceiling, How to

[Kizza]

What's the best way to create the ceiling shown in this image from the 2015 teaser?

I have an upcoming project which requires a similar ceiling.

I would probably done it with a EAP for the edge and using a solid addition for the main...

Or should I use a slab?

I would (and have) use slabs and walls......you can bound the slabs and ceiling-walls to each other and other defining walls, thus using the flood method to create the ceiling slabs incl. the fact they will auto adjust if you move any walls....

I should clarify, the ceiling directly above the chairs..not the load bearing components.

[VincentCuclair]

No need to clarify, I got it the first time :grin: and my advice still stands...

OK, thanks. I'm not sure how to create the step down for the ceiling using slabs and walls though.

Yes, that's what I thought you meant. So it's not really one seamless ceiling is it? I know that they are auto bound and all, but three objects...

Would be better if we could assign a user defineable profile to a slab object (ceiling object). That would be a more logical approach IMO.

Guess a wish for another day..

and thanks Vincent.

1. Create 1 (or 2) ceiling layers

2. Create 2 (or 1) ceiling types that you are going to have (2 if you only use 1 DL, with an offset corresponding to the ceiling height difference)

3. Create a wall build-up to correspond with the build-up of the vertical ceiling part, here you can either bound the top and bottom of the wall definition to the 2 ceiling layers or if you only have 1 ceiling layer bound the bottom and offset the top to correspond with the height difference.

4. Draw the vertical parts in the correct places.

5. Change layer settings to view/snap/modify others and place the correct slabs by choosing the correct enclosing walls and ceiling-walls.

6. Done

Should be a little easier with levels I would imagine.

But understood. Thx.

Perhaps but that edge is not always vertical or indeed even straight.

In Sweden they actually build those vertical sections using the same technique as in metal stud gypsum walls, so technically the way I do it is correct not only theory.

(Do those vertical sections actually get delivered as part of the ceiling down under?)

Using your idea of a "Building Element" tool and adding the ability to create a profile to use with it, you could ditch the slab tool and would have created a ceiling and foundation tool in one!

So how would you define the sections that are lower/higher once the slab is placed?

Come to think of it, if introduced, it would be a nice added functionality even in all other instances we need varying slab heights.......hmmm, needs some pondering before a wish is posted......

[Kizza]

They are either boxed in after or are manufactured as part of the truss.

[VincentCuclair]

.....telepathy :grin:

[Kizza]

So how would you define the sections that are lower/higher once the slab is placed?

You enter a profile edit mode (similar to group edit). You would also need to define the extent or path for the profile to follow.

So, create a path (similar to an EAP) create a profile (similar to EAP) and if you need to edit it, then you enter a profile edit mode.

Here's a simple detail of this I did in an earlier project......

Undertak = ceiling

Gips = gypsum

That looks like a paneled suspended ceiling detail.

Can I ask whats the purpose of the non seen right hand vertical gypsum lining on the lower ceiling section?

Is it some sort of acoustic or fire treatment?

[VincentCuclair]

Yeah it is, it's mainly to give the whole vertical section some more stability and tie it all together better (plus I don't trust the guys on the building site to put the ceiling at exactly the correct height so if it ends up a couple centimeters higher it still looks acceptable... )
