Setting pitch of a helix with Series Division


(distantkitty) #1

Hello,
I’m trying to make a helix with 90 points per revolution – or every 4 degrees. I’m running into a snag on how to make the pitch definable. How would I assign “Step” to be 4 degrees at XXX pitch.

For instance, I would like to handle variable height but a definable pitch that has 90pts per revolution, say 1 rev/10mm, so at 20mm there would be two revs and 180pts. Attached is what I have been trying to work with.

Thanks!

I think this is what you are looking for. I also included a Python definition which does the same thing.

Wow, this is exactly what I was looking for. I guess I was way off with my approach.
Thanks!
