Point Selection Help

After figuring out how to extract isocurves with GH through forum search, I divided points from them of which I want to use some as input for an interpolated crv.

My goal is to create a spiral curve on any revolved surface. I was hoping to realise this by selecting +1 point deeper down per isocurve as shown above. I have attached my script and am hoping someone can help. You will need to reference a quick front viewport profile curve for the revolution to get started.

Thanks in advance.

You need to shift list every list in 1 incremental step... for that you can use a series number component with the same length number that the number of curves. Then you use flip matrix to change/flip the list order and then the curve component (interpolate curve on the image).

In the W input of the shift list, use TRUE option.

if you want you can search for tutorials about list components...

tip: for curves on the other direction, you can use negative values with the shift list component.
