Bemfarmer,
Boolean issue?

What I would do is create a "profile" of my bottle (then run rebuild if it was segmented, like a rounded corner rectangle) then run the bottle array on the profile and choose a ridiculous amount of stations. Then loft those and do the Boolean diff with the new, single solid.

I have 1 question for Michael though.

Is there a way to set "an attachment point" to the bottle? If I have an elongated rectangle for a bottle for instance, and I want to set a "depth" of the bottles placement on the helix start point, the bottle "moves away" from the depth and helix as it rotates to the narrow side of the bottle/rectangle. So if I make a variable helix with a start radius of 5 and an end of 3, My resulting bottle at the minor radius' endpoint has moved out and away from the helix path.

Not sure if/how this could be done.
