    Hello
    I'm trying to find the best approach to create a group of splines that are starting at one point, but end up spread apart
    Here is a file that shows what I am looking for.
    You can see that the splines all start from a circle, and then they go towards a large cube. The idea would be to be able to spread the end points of the spline to different parts of the cube so they don't just in a "bundle"

    I did a little doodle in the file to show the effect.
    https://www.dropbox.com/scl/fi/ajwlpnfkot5sm2975fud3/SplineCable.c4d?rlkey=j8branl3zqe77i62s9v5c3vx9&dl=0

    I tried doing this with X-Particles and having the particles follow a spline with an offset, but it didn't quite do what I needed.

    Ideally I'd like to find a solution that allows me to not have to draw each spline individually, but in the same time gives me some flexibility to moving the end points.

    Thanks for any ideas!

      Hi AlexC,

      Please have a look here.

      I have set up an example with 100 Splines; please let me know if you need more or less.

      They Start from the Null "Spline_Start_Point" and end on the Cube's Polygon Selection.

      I have placed a Catenary Spline Modifier in the Spline Group in case they need some "gravity fake effect" in the middle.

      If the Spline ends are not at the Point where they all join, then the question is, how would you like to move them?
      1
      This could be done with a Plain Effector for one direction and use the theMoGraph Weight select to adjust based on the painted Weight on the"clone" and how much it goes up or down.
      Which would also require a weight/effector combination for other directions.
      2
      Finding the initial setting is more straightforward than switching off the XPresso and changing the points as you like. Switching the XPresso back on erases all of that change!
      3
      Another option would be to produce polygons on the surface and use those (Connect) as Mode: Object in the Matrix, so you can move them individually.

      All the best

        Thank you Sassi, this is great! Gonna play around with these options.
        I think the polygon selection approach (option 3) might be the best, but I'll test.

        Thank you!!
