      Hi,

      I'm trying to project a helix on a surface.

      I combined the structure of lines created by the rubyscript grow.rb

      with a shape:
      0.jpg

      and then by hand connect all intersecting lines to a helix and delete
      the remaining lines:
      1.jpg

      so what I'm looking for is a script that connects intersection points
      of lines with a surface:

      2.jpg

      Is there a script known that can accomplish that?

      Thnx in advance

        The images aren't showing up. I think I need to see them to understand better ๐Ÿ˜„

            Hi Liquid,

            I'd rather draw a helical ramp (or call it anyhow) and then intersect the face of the jar (or what it is) with this ramp. Note that the ramp is a group in my attached model so you can easily hide/erase it afterwards and only keep the intersection lines nicely added to your surface.

            HelicalIntersection.jpg
            And the skippy (helix_13.rb and skin.rb was used to create the helical ramp)

            HelicalIntersection.skp

            Gai...

              Thank you, well done!

              only thing is: skin.rb does not work for me on a helix formed line,
              is there something I should think about? (Settings? version of skin.rb?
              grouped? slice amount????)

              (edit)I figured it out myself.. tnx so much!

              Thanks

                Now for the next challenge:

                I projected a double helix on my vase:
                vaasgroot.jpg

                now I want do delete the small strip :
                vaasklein.jpg

                but i can only select one piece at a time

                is there a solution?

                  I did it using a snippet of Ruby - please go over this to make sure it's what you want, and to make sure the script didn't miss anything.
