Karsten et al,

I'm attempting to build a toroidal helix form.
The coil rail works well but I am experiencing difficulty attaching the profile for sweeping.
I've output x,y.x info from inputs to generative array into point&frame for circle ,
and at first it appears to be on the right track, however as the animation shows
changing the coil size shifts the profile from the starting point of the rail.
As a consequence the sweep does not give the desired result.

Any thoughts?
