Hi Michael,
thanks for the script but unfortunately its rotation is in the wrong axis.
Attached is a basic drawing where I have manually rotated a few bottles and
placed them on the helix. You can see from the photo's the facets are cut at
90 degrees to the shaft axis. Also I have shown the result of using the profiles only
and sweep you can see if the profiles where extruded they would cut thro the screw.
The array along curve drawing shows the bottles arrayed at 90 degrees to the shaft but
with no rotation.
Cheers
Barry
