Running a sphere along a helix that is wrapped around another helix
Currently I have a set-up a shown in the SS with a helix, in white, running around a large helix in green. I would like to run the red sphere along the white helix however when I use align to spline in this arrangement it runs along the helix as it was before it was wrapped around the green helix. Does anyone know how I can run the red sphere along the white helix as it is shown? Many thanks in advance.

If you right-click on your helix with the spline wrap effector applied.
Select ‘Current State to Object’ and a New spline will appear with that deformation locked in.
You can then drop that new spline into the aline to spline tool and the ball should move along the desired path. -
Hi Benjamin,
Thank you for your reply. I’ve just tried as you suggest however I’m still getting the red ball running along it’s original path, ie that contained within the purple guide lines. Am I doing something wrong?
Kind regards

Hmm, that’s strange I copied your project and it works on mine, are you using r19?
If you are I’ve attached a copy of my project file for you to look at.
Hope this is useful

you can try using a MoSpline to ‘capture’ the shape of the spline-plus-deformer then have the sphere follow the MoSpline, like this

Hi Benjamin,
Got it! I followed the way you’d set up your file including removing the null, which was unnecessary and bingo, it worked. Many thanks for your efforts in helping me sort this out. I’m using R18 but it opened your file no bother.
Kind regards
