Grasshopper surface-surface intersection problem

Hello people. I have a (i assume) very basic question. I’m trying to construct the hull surface of a boat based on some numerical data. I am also supposed to obtain the same numerical data from the same constructed surface as if i do not have the initial numerical data as the second step. I have managed to do the first main step, constructing the lines and creating a network surface. Problem starts at the second step. I want to find intersection lines of one surface and a series of surfaces t…
