Hello! I would like you to help me create this shape

I can’t find the right way to do it. I need your assistance, please

a very fast and simple approach:
create a staring surface / end surface as helper.
some lines inbetween
_loft (match start / end tangent turned on)

you might get closer to the design if you work for each half of a wave.
But sitll loft will do a great job.
building one “half wave” in the middle, arranged at the right

hope this helps - kind regards -tom

Thank you very much, you have helped me a lot. My question is, can it be done with Grasshopper?

Many ways to do this, and each way has many possible parameter values that affect the outcome.

P.S. Using Jitter gives minimal and indirect control of the second edge. Way better to use two Graph Mapper components (below, version ‘b’), each with their own ReMap ‘T’ (Target) slider.

Added a ‘Length (X)’ slider to set length overall, corresponding to ‘Width’, and compute Series step value from it, so count can be changed without affecting length.
