Generating a helix

Hello,
How can a helix be generated in grasshopper? In Rhino a helix command exists but I would like to have the radius and number of turns to be controlled by a slider.
Thanks!
Carlos

Its because you're using the 5.0099 build. It was done in 6.019. You should really update as the 6.0 stuff has lots of useful additions such as data trees and a whole host of other things.

Joshua - I ran your helixAlongCurve.ghx file in GH 0.9.0076 and noticed that it has the same problems as the much simpler Sin/Cos solution posted at the beginning of this thread. That's the method I use for generating 3D printed screw threads and other helical shapes, but I have to whack off the top and bottom parts of the helix because the start & end section aren't quite correct.

Could your version fix this, but only in GH2? The attached pic shows the top view I get of your method. Is the GH2 version different?
