Hi everyone, I'm very new to ArchiCad and I have just downloaded it. I have no experience at all in Archicad, so pardon me for my slow learning.

Please let me know how to curve a flat slab. I've google it but I've got no result. Then I come across this forum, hoping to get the answer.

Archicad is fun, but I've no idea how to play with it. :cry:

Start with the Getting Started document under the Help Menu.

You'll see how, by hovering the cursor over an edge of a high-lighted [selected] slab drawn as a rectangle, a palette is displayed where the slab can be edited - one choice is an arc. Picking this option will allow you to pull the straight edge into a curve.

But you can't arch a slab since it is constrained to operate laterally only.

It depends on what you mean when you say you want to curve it - or rather curve it on which axis or plane. Curving a slab on the XY plane or the plane along which it lies is just a function of what you do to its edges or its overall shape, looked at from above - as Dwight described above.

Curving it on the z axis is another question altogether and is strictly speaking not possible because of what defines a slab in ArchiCAD's GDL language ( in other words, you may be able to do it with an add-on like Maxonform, but it will no longer read as a slab, for documentation and operational purposes.)

Your best bet then would be either to use the complex profile manager with a wall tool ( assuming your using ArchiCAD 10 or 11) or ( if you're using AC9 or below) to create a new object by drawing your desired curved slab on its side using either the slab tool or the wall tool and then saving that resulting geometry as a new 3D object that lies the correct way up when you load it. Of course like I said before it will not read as a slab then but as a static object.
