How to get non-parallel dividing lines based on the irregular surface?

Hi, guys! I tried many ways, but i still can not get the spliting lines like the black lines i draw according to the shape of one irregular surface. Do you have any solutions without the plugins? Thanks in advance. The file is atatched.

Hi,

are you talking about something like this? I just used the Surface | Curve component.

Sorry, i mean i want to get the spliting curve just from the input surface

Something like this, then? Do you just want to split the perimeter of the surface?

Thank you. But I mean the input are the surface and the distance, the output are the lines which splitting the surface.

OK, now I understand what you were looking for, apologies for the previous answers :sweat_smile:

I am using percentages instead of distances to create the lines, could that work for you? If you use distances, all the lines would be parallel to one side of the polygon.
