      I'm sorry. That would be the paperclip nautilus.

        an exploratory go at the basics.. not sure how deep into this challenge i should commit to.. i think it could get pretty intense 😄

        spiral.skp

        basically… curve maker & curviloft

          Here's a Nautilus made with a component 'wedge' and Grow...

              Next step: curve the chamber partitions.

              I take the slow, deliberate approach in my aimless wandering.

                It can't be done using one distorted component, because as the instances scale they no longer line up with their smaller neighbor, getting progressively misaligned...
                If you explode it you can tweak all of the vertices of the parts so the all align smoothly...
                BUT there are hundreds to do...
                A nautilus is not always a perfect Fibonacci spiral anyway... and as you say the cell dividers are curved in 3d too...
                It could be coded - but I am NOT going to do it...

                  Can't hardly blame ya. You do enough around here already. And your two illustrations are no mean feats in themselves.

                    I turn my back to get some rest, and you guys make my day.

                    I'll expect the fleshy parts on my desk by noon.

                    EDIT: Some noon, any noon, any noon anywhere.

                      Jeff, could you or someone else who gets it, explain the use of curviloft for this model (your model, a few posts back). Your pic did not do it justice; very nice model, I think.

                        Oh, I think I see the smaller arc now. So, 2 arcs and the spiral path?

                        hey brooke…
                        i actually did 4 different surfaces (breaking each one down into input that curviloft can understand..)

                        individual surfaces still grouped.. prior to exploding & soften/smooth

                          That's very helpful. Thank you much. Very nice.

                            No... I mean yes, but no faces as I had thought but did not say.

                            And news to me, the beginning and ending arcs (profiles, 'contours' as Fredo calls them) need not touch the path; in this case they would break the curve so that is fortunate.

                            So, I did OK but for the wrong reversal. Please advise. (Looking closer I see there are other errors: lack of closure, intersections, etc..)

                              I saw a twitch in this horse's left nostril. Besides, chambered nautilii really don't look like this. This one is with 'follow me and rotate': settings: rotate 0, scale 1.03; 24 segment face flat helix.
