How to find center curve of face with Grasshopper


It may sounds weird but i want to find center curve of face

If i got this mesh, i want to find

center curve like this.

I think i can find edges of this mesh and divide it,

But are there some neat ways to get this?

Can you upload the 3dm and GH files?

Thanks for the reply but I'm sorry that i didn't make that shape by grasshopper, And i solved this like below after upload this question

Better way? when… i just have that mesh only.


How about TweenCurve?

IsoCurve is also a possibility. That way, you can input the Brep face (Surface) you want and don’t have to find the edge curves.
