I believe that must be easy but I am a little stucked in the nodal world! :)

(no nodal file inside) Curve can be any flat curve like a Sinusoïde etc...Hllow object can be any thing like a bowl etc...



I make a "Flat Extrude" +"Vertical Extrude" because "Shell" is not yet implemented (Vertical Extrude Line + Shell)

All that for simulate this function! :)
