Evaluate point on curve but related with lenght curve?

hello guys!!

it’s a simple question, i already make it work in the past but i dunno why in this definition i cannot make it work :frowning:
i need to know at which parameters are the points of green curves in the pink curves, but like not reparametrizazing, but related to the total lenght of the pink curves. example: my lenght of the curve at 0 index is 6083 meters long, and when i use point on curve, t parameters are until 24 (dunno why).

i need this so i can do like an “offset” of the green curves but related with the pink curves using evaluate lenght (i will add/substract n distance from the t of those points, to the left and to the right).

thank you in advance!!!

Curve parameter has nothing to do with curve length. Use Length Parameter.
And check linked recent topic out regarding curve domain.
