Connect points with straight vectors (how to make a list)

Hi Everyone, 

I am new to the forum and a beginners with grasshopper.

What i am trying to do is having an interior made out with different layers of bamboo.

I can create one single layer. dividing a line , projecting and finding the intersection points with the final shape of the layers i am creating.

when I try to make the same process with more layers the vectors just do not go from point A to B but they go randomly (or what seems to me...) to everywhere.

I belive is a list problems, i probably need to ordinate that points...but I really do not

how to do that.

Thank you

Alberto
