and the link to download the Archicad 16 Edu -file to try it by Yourself in 3D:

It offers You 2 nearly the same GDLs for shield tiles.
The one for the bottom can follow contours up to 18 Points You can grab and drag.
The one for the Walls can be situated in the groundplan around the Room-contor. After this little work, you can turn them upside and work in 3D to edit the shield-Tiles like change the Angle, "pan" the Start-Point and so on.
It is possible to shift each 2. row - so that it looks like a brickwall.
Have fun with it and write some response.
