Point numbers

I have a set of curves, whos points I want to set numbers to. Then I need to unroll these curves and mantain the numbers for the corresponding points of the unrolled curves. Any ideas how I can do this? I need to mantain the same numbers on all corresponding points.

what do you mean by unroll?
the three you provided seem to be a projection, the top-most exploded while the other two not.
see attached. when you project, the vertices and segment order of your polylines are preserved. unless you mean something else by unroll…
