Hi Burr thanks yeah array circular using a vertical step makes sense to me now. I'll see if I can adjust the script.

@Brian, I was thinking a bit whether the script should take the parameters for a helix and use helix calculations in it but like you mention it would be easier for things like variable spacing for it to take an already made helix curve like it currently does. I should be able to use a rotate with reference points to do the other kind of rotation, I'll try that in a moment here.
