How can I make a design like this?

search “parametric benches” on this forum. They are done the same way.

Also waffle structures.

It’s a wavy surface that has been sliced into sections.

Although the wall and bench parametric designs have similar inputs, I can’t give depth to the curves as in the picture.of course, as a final, I use top-ups and divide them into pieces, but it seems to me that I’m following the wrong path.
