Problem with projecting a curve onto a brep

Hello everybody.

I’m trying to obtain some sections from a manipulated hull surface. I have created series of lines and been trying to project them onto the surface. But probably since i have created a surface by joining 3 seperate surfaces together, some of the lines are not projected on the final surface.

How can i manage to solve this issue? I am adding pictures and also rhino & grasshopper files. You just need to set the surface in rhino file to initial surface commands in grasshopper to run the code. Thank you.
