How to place object on spiral path?
-
I need to place about 100 small balls (1/4 in Diam) on a spiral path. I can define that path with a spiral line that loops back to join itself, like a string of pearls wrapped around a wrist.
Anybody got any idea how to do that?

Component Stringer, just remember to not join the end of the path, it won't work on a closed loop.

Thankyou Thankyou. Box and especially Chris.
Took me less than 30 minutes to do this. About 10 minutes to make the path, about 20 minutes to make the ball and tweak it, and 30 seconds to make the bearing group.
I remember about 2 years ago I did this same construct the hard way. Took almost 2 days to get it right.
This is an updated total redraw of the machine.

Create the sphere, make it a component, plugin/screw, click first point, click second point, precision 12, number of turns 5, enter, wait few seconds..... done. less than 5 minutes.

Thanks, but for my specific problem that would only be a partial solution.
It would do the spiral portion OK, but my bearings do a loop back through a specific path, that your solution could not handle. It would require a secondary operation to place bearings on that loopback path, and while not a difficult job, the "String Comps" Ruby did it all in a single step, not counting the path definition step I would need to do for both, if only partially for your solution.
