Hi all, I would like to achieve a patern similar as reference picture in grasshopper, I was thinking using some lines and fields to get this wave effects, or trying with lunch box rhombus but I’m affaid I will not achieve the waves in this case, do you have any recommandation or reference topic to biggin with ? Thank you in advance 
Hello
in order to analyze that, begin by drawing main curves in rhino, begin by a curve, then the second, see what logic appears, and then when you have some logics (scale, translate, sinus, deformation …) you can then begin to implement that in Grasshopper.
Field is also possible, I’ll give it a try!
For field use some line that follows the flow.
Then smooth the vector field.
Then follow the flow of the vector field using field line for example. Use for example a line on middle of the pattern, with points
But first method is surely the best.
