Sine curve on spiral

Hello!

I need some help… I’ve created a spiral using grasshopper components and I want to create a sine curve along that spiral. I’ve tried many hours and different scripts but I can’t seem to figure it out…

Can someone help me out with this?

Thanks in advance! :slightly_smiling_face:

maybe this help :slight_smile::

Yes I tried this one but I don’t want the sine curve in the Z direction… I want it along the X-Y plane. Hope you understand :sweat_smile:

You can use the tangent on the spiral point then with a cross product with Z find a lateral vector that will be used to move the points.
Something like that

oh okey cool, I’ll try it out now! I just have to download you plug-in first I think :slight_smile:

You don’t need my plugin. Just copy the components after the spiral and apply it to your spiral. I just put my plugin as I implemented some different spirals and some functions.
