Maybe More easy : Select all tapered helix and use the Scale 1D :)

Hi Tim, I have tuned this up for the next beta so that it will now allow the start and end point at the same location to make a flat spiral shape.

There is also a new "Flat spiral" button that you can push instead of picking the second point of the axis to do the same thing.

I'm not quite sure yet when the next beta will be ready, it has taken me a while longer than I thought to fix up some problems in Network surface, but I'm making progress.

2 possibilties to make the same thing in the menu, that is not optimized!
I am joking of course :)
