| Apr 22, 2016 at 2:38 | comment | added | tsuresuregusa | @J.M. I tried a few Archimedes' spirals but it doesn't really work, you need to add some kind of "asymmetry" (for lack of a better word), that's what my 1 + a Sin[\[Phi]/2 + f]/4 + a Sin[\[Phi]/4 + f]/4 is doing, modulating the radius of the spiral to try to fit it the real scroll. I thought about subtracting a simple spiral to the edge and fitting the difference to a function with FindFormula but don't really know yet how to yet. | |

| Apr 22, 2016 at 1:50 | comment | added | tsuresuregusa | Maybe I should rephrase it as "don't use BSplineCurve" which would be easy enough to fit with enough points. Let me try to edit the question | |
| Apr 22, 2016 at 1:46 | comment | added | J. M.'s missing motivation | Okay I'm confused: splines are still piecewise functions after all, so you seem to have conflicting desires. Also, "with compass and rulers" can be taken to mean that the arcs could very well be made up of circle arcs and line segments suitably pasted together. | |
