You will need to create the arc for one side only, thendial in your magic wand settings, and use the barrel vaulted geometry method of the roof tool and the magic wand to create one side, then mirror a copy it over.

That's the short version!

Easier than dealing with the roof tool and making a barrel vault roof,
is to use TrussMaker. It makes a smoother looking surface with no joints.
It may be possible to make a barrel vault using a complex profile wall.

Better yet... If you use the beam tool it will automatically cut its own hole in the slab.

Im very very dissapointed!!!I ve worked for hours trying to design what i want and nothing came out!I ve tried both ways and no results.I ve spent a lot of time studying the help files but again nothing .Im thinking to post a long reply with everything Ive done and i ll trully appreciate if any of you could give me instructions of what i did wrong and help me do it!!!Im stuck!!Please help.By the way I find it disturbing that a software such Archicad hasnt got a tool for this job.

Georgios,
Can we agree that what you want to make is what is commonly known
as a barrel vault roof with 180° of included angle ?
If so, there are several ways to accomplish this.
I will only describe two ways hear because they are the easiest
to describe and the easiest to do.

One- use the "Shell 10" object in the Basic shapes folder in the
Archicad library.

Two- Use TrussMaker. Draw an 180° arc in a section/elevation window
Make the radius of this arc the radius of the under side of vault
plus one half the thickness of the vault shell. Select the arc,
go to design extras->TrussMaker, select the cross section shape
solid beam, enter the vertical dimension as the thickness of shell
make the width three or four meters, and hit OK.
In plan you will see the 2D symbol of the barrel vault with
center line lying along the section tool line. Stretch the
2D symbol to the length of the vault you want and check
in the 3D window and see if the vault is what you want.

The result was really good and the way using the 'shell 10' object more than easy!I must be blind not to see it my self.Thanx a lot again Peter.Here is the result....

Using the profiled beam method, I just put this together in a few minutes. The beams are each half the vault so that they can miter properly at the groin.

I am running out to dinner so I don't have time to make examples, but...

Go to Design > Complex Profiles > Profile Manager (I hope this makes sense for the Greek version). This opens the editor for making and revising complex profiles. Draw a fill to define the profile, select whether it is to work as a wall, beam, and/or column and store the profile. It will then be available to draw with using the appropriate tool (select the profile method in the Info box or settings dialog). For further info read the manual. If you have any problems post back here.

Hello Matthew,
Just a quick question.
Why do you prefer a profile beam vs a profile wall in this context ?
Thanks,
Peter Devlin

Personally, I prefer beams for trim since you can slope them when needed.
