Curve Ramp !!!

[Anonymous]

how can I make this ramp on Archicad12 ?

(the gray fill)
it's not a straight ramp neither a curve one...
I try the custom stair, but doesn't worked... I thought the mesh... but it didn't make a correct model...
Can anyone help??

Thanks

If you want uniform thickness, you might try Mesh3D which you will find by a search in this forum (select Search to the right of FAQ above)

Edited:
The right one to use AFAIK is "Mesh3D 2", by Petri and edited by Braza, and found here:

Or this one "Mesh3D 1", edited by Olivier Dentan - I don't know which is best? Or if there is any difference?

The forum's search engine isn't very good at finding items with spaces in their name, alas.
