Extract centerline from mesh surface

Grasshopper

Hi,

I want to extract the surface edge as the centerline of this volume. since its a mesh profile i cant get a clean offset of the edge as it will expand multiple direction. I beginner in grasshopper and not yet can create my own script.

Thanks in advance :slight_smile:
