wavy roof

[Anonymous]

I'm a beginner with Archicad. Been using it for like 2 months now and I know the basics..but when it comes to something difficult I'm having some problems.. I'm doing a project in school and we have to design an art gallery. The most special thing we want on the building is a roof and now I have problems how to design something like that in archicad.

Our building is build near a hill..like just a little part of it is in the hill, but most of all is outside..and the front part is near a river. What we want to do is that the roof would be like a bit wavy..that it would look like it is
- afflux of the river or
- continuation of the hill
Something between those two. It would be build from like 3 waves.

So my question is how to make that kind of roof in archicad? If it's even possible.

p.s.: sorry for opening a new subject but I didn't know where to write this and I hope I decribed my problem as clear as possible.

There several ways to make a wavy roof in Archicad.
If you are working in a version before AC 8.0 then there
are only two ways, the roof tool and the "Profiler" add-on
(it would be good to know your AC version and platform).
If you are working in AC 8 or AC 9 then you could use
the mesh tool and SEO as well as the two methods mentioned above.
If you are using AC 10 or AC 11 then you could use a complex profile
wall or beam. If the surface is complex in all three axes then you
could use the mesh tool and SEO or perhaps the object described here

Thanks a lot for the answer.
I'm using Archicad 11 (educational version) and WinXP SP2.
Can you please describe a bit more how I could use a wall or beam for the roof?

Yeah and I read that I could use a mesh tool for the roof too but I don't really know how to make it look like a roof then. What does SEO stand for though?

Wow..this is really very useful and nicely described. I've never looked in this guide before.

Thanks!

Please see this thread for a discussion of how to make a roof from a mesh.

Please look in the help files for the term "complex profile".
You can draw a cross section of your roof using the fill tool in
the complex profile editor, save it as a custom profile, and then
use this shape as an extrusion with the wall tool or the beam tool.
If you do a search using the key word "vault" or "barrel vault"
or "groin vault" you will find discussions about how to use
complex profiles to model roofs.

Thank you so very much...you're a lifesaver Need to have the project done till tomorrow and that was the only thing left to do.

I read some forums and took your suggestion and now I tried and made a roof in two different ways, with beams and with mesh. And it worked both way. I just don't know where to convert a mesh or that beam into a roof. So I could trim walls then to the level of roof.

Use Solid Element Operations. The you can skip the convert to roof step.

I was able to convert mash into roof, but I couldn't even trim walls even if I wanted, cause it isn't working ok with that kind of roof, cause it only trims walls that can stay straight on the top.

How can I use solid element operation in that way? I read it in archicad help and try it but nothing happens. Guess I don't know how to set it up right.

I guess your mesh is either not solid (just a wavy surface) or has a flat bottom/underside).

use the beam roof instead, as operator, and select all the walls as target, then subtract with upwards extrusion.
