There's been some discussions on how to create spiral/helix in this forum.
It thought it would be a good idea to write a quick tutorial on how to do this using the new array function.

The tutorial (PDF format) is intended for beginners and was some kind of "training" for me so i'd like to know what you think of it. Is it useful ? Would you like to see more ? As english is not my native language, do not hesitate to report faults. Feedback, comments, suggestions for improvement are welcome...

Also enclosed is a .3DM example file

Hope you'll enjoy it...
