Hi Brian, that sounds logical. Thanks for figuring it out!

Previously Barry wrote this:

"The bottle is always vertical to the horizontal
screws and only rotates in the plan view."

I was focused in on that "only rotates in the plan view" part and so only did one rotation.

So Barry, can you please clarify that so I can make sure - at each station you need the object rotated in 2 ways, once in the plan view which is rotating around the world z axis, correct? Then another rotation around the cylinder/helix axis direction which is the world x axis?

It might simplify things a little bit if the cylinder/helix axis was right on a world axis starting at the origin, will that restriction work for you?
