Is there a node(s) that can plot cylindrical/polar coordinates using: Radius(t), Angle(t) and z(t), instead of the Point-node which maps Cartesian x(t), y(t), z(t) coordinates?

I managed to create a Variable Pitch - Variable Radius (vP-vR) Helix NE macro attached here
Thanks to Brian’s instruction pdf and his VarPitchHelixExtremes.js script.

Having difficulties Flowing a custom Helix over another custom Helix.
(Red line is the minor helix)

Can only Flow the MoI Factory Helix-Node onto another Helix.
(Red line is the minor helix

I am hoping that using cylindrical coordinates to describe the Minor vP-vR Helix will make it easier to ‘Flow’ it over another Helix? As there would be a centre reference for the axis to follow.

Any other suggestions are welcome.

After a very brief peek, the FLOW Base for your first .nod appears to be very short, 10.4 units, versus 200 for the second node.

Hi Brian,
Thanks for your help and patiens. I think I’m finally getting the hang.
Could not have done it without your scripts, documentation and answering my stupid questions.
Just one more, if ok with you.
How did you work out what to do with the [t=i(numPoins-1)] and [R2 = UserEnteredValue – R1]?
Without me following your Scripts, I would never have worked that out.
