Unroll lines with intersection point

Hello everybody, i am working on a weaving structure out of stripwood on
a double curved surface and i need help!!!!

In my definition i have several problems which i could not solve until now:

1. How can I bring the exact intersection points with the right lenght of the curve in between to the y/x plane?.

4. For structural reasons it is important to have a bigger height in the
middle of the weaving structure (it means the amplitude has to be
bigger). My attractorpoint solutions did not work.

Any help is really appreciated because i am totaly lost with these problems espacially with the intersection points on the 2D plane.

Cheers

I think the main problem what i have is that i don´t understant how parameter "t" is working. I made intersection points to get the parameter of the curve for the "shatter" tool.

but this dit not work as you can see in the image below

is there a way to measure the lenght of the curve between the intersection points? Because i need the lenght of the curve between the intersection points to create points on a straight line.
I thought the best way to do this is to shatter the curve and to take these parameters to a straight line with the same lenght like the curve, but this dit not work.

Not sure where exactly you want the attractor points to work.

I cleaned up your definition for you and solved the remapping. You only need to analyze on the new curves the same point along the curve from the original curves.

Hope that helps.

Thank you so much Elizabeth,
but i think i haven´t understood what you mean with "You only need to analyze on the new curves the same point along the curve from the original curves"? When i open your definition i still have the same problem that the points don´t have the same distance after remapping them with "Eval C to the line. There are too many.

concerning the attractor point, i want the amplitute of the structure on the border smaller than in the middle. What i did in the definition did not work.
Thanks again

i still do not find a way to remap the intersection points on the new line.
Sorry for my stupidity but i am a beginner in Grasshopper.
