Flat slab with sloping top surface

Gurus
Is there an easy way to draw a concrete floor slab with a flat underside but sloping top? One often has to construct slabs for outside decks that incorporate a slight falls for drainage. It is not the same as drawing a ramp because these have sloping undersides and tops.

Mesh?

Thanks Stuart. I know about meshes. However, using a slab and shaping it in-situ is probably more flexible. However, I'll use the mesh method if necessary.

Enter the Shell tool in AC 15. It can be classified as a slab. Will show up in plan, 3D, elevation/section correctly. No SEO or workarounds needed.

But let me add that the source and basic info on which this article (and many others) is based was posted here on ArchiCAD-Talk by various members.
I only put together an article based on info found here.

Hi ..again

I've been exploring the new shell tool and obviously , it doesn't resolve the problem .... no way to have changes in thikness when adding points with different altitudes in the shell tool

(it is also impossible to add point inside a shell )
