how can I create the pattern and contour of this item in rhino?
i believe its a gradient scaling of a diamond grid created on the polysurface(open box).
this could be done by any of the various panelling plugins- panelling tools, geometry gym, pufferfish etc.
I think the ‘wave’ effect is because of the polysrf being modelled like that.
thank you Aditya, but I didnt get the wave effect, how can I on a flat surface with a polyline create this contour like effect?
instead of extruding a rectangle to make a box you could loft some curves 15802207925849114511572039024245|375x500
Did you try emailing Alessandro to ask him how he did it?
