I am trying to create a **Circular curve** that would define the boundary of a pringles chip (hyperbolic paraboloid) like the image attached, but i keep getting stuck with the coordinates of the Z for the point.

Is there a simpler way of achieving the same?

I have already seen this video Grasshopper Lecture 06_Pringles Chips with grasshopper - YouTube

but it doesn’t cover a hyperbolic paraboloid **Circular** surface, it just covers a square and then pulling the geometry to the surface that doesn’t work for me.
