A small incursion on ribbing, easy enough as an experiment, but here is the result.
Just some curves, a loft and surface.
Give the surface some thickness, duplicating it and create the lateral surfaces (_EdgeSrf), join all surfaces in a closed polysurface creating a solid.
Create the contours in y and x direction (Contour command, with join curves by contour plane option)
Then after obtaining the ribbing, load the ribs script. I've used the script by Un Didi, Kudos to him. And I must also thank Rodrigo Medina and Andre for the pointers.
So I'm still yet to test a unroll script, let's see if I find some time to do that... pointers are always welcome.
