Selecting x+1 points of each divided curve

Grasshopper

Hello,
is there a way how to select the first point of first curve, second point of second curve, third point of third curve, etc etc… would like to interpolate a curve along those points which would eventually wrap around the shape. Attached are the files and image!

would appreciate any help

Here’s a different approach to your goal (using IsoVist Rays).

Includes a simple script to pull the resulting curve to your original mesh (not as crucial if you use a small distance between contours).
