Mar 31, 2017 at 15:35	comment	added	Dan Bennett		Yes - if I could get the CNC data from the machine for animating the cone, that would be cool. :)
Mar 31, 2017 at 15:15	comment	added	lemon		@DanBennett... oh, ok.. I see what you mean now. The orientation of the cone in this configuration needs the cone to point to the tube. But this ray cast could be done from every directions. The only needed point is the ray has to hit the tube. See what I mean? Of course, this is not a real physical constraint here. What I have in mind is placing and animating thing in the good orientation may do the job. In certain meaner, the same way the real machine is coded to orientate things correctly
Mar 31, 2017 at 15:10	comment	added	Dan Bennett		Thanks, Lemon - your answer's very good. The method of adding vertices to the strip is very powerful - I wasn't aware it was possible. I don't think your to-do list indicates that the main change that's needed is for the ribbon to arrive at the vessel on a tangent, not on its normal. At the moment it looks like the incident ray is a paint brush, rather than a ribbon that's under tension.

Mar 31, 2017 at 14:50	comment	added	lemon		@DanBennett, yes, I had no time to go further, but, the main point here is to do so the cone always points -Z to the tube (as the ray cast is along this axis). If you do that (by a constraint or other), it will continue to "project" the strip all around the tube. Now, also read the "to do list" at the end of the answer.
Mar 31, 2017 at 14:26	comment	added	Dan Bennett		Thanks, Lemon - that's intense! I think if I study what you've done I'll double my Blender knowledge. :) One thing, though... The ribbon arrives at the tangent of the vessel, not at the normal. The video in my original post shows this.
