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! 
maybe this help 
:
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 
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
I added in Nautilus some zig zag and others
oh okey cool, I’ll try it out now! I just have to download you plug-in first I think
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.

It works, thank you!! but I want to try the spiral component from your plugin bcs it looks a bit better I’m gonna try and download it!
it was better if you notify X-Y plane in your topic first.
i am late but using Delrieu plugin and extend:
The spirals in my plugin, 2 are from Rhinocommon
well done,may i ask how you display view as frame in the grasshopper screenshot?
It is on the menu on the left of grasshopper. I am no more on my pc so I cant make a screenshot.
Thank you again for the help!
