Hi, the explanation for the “Flip” in tilt is same reason as here:

> Thanks… Cross product between unit vectors has magnitude 0 to 1. That should tell you what is going on… So using only cross product there is no way for the curve tilt to tell how many revolutions have gone by so when the curve completes a “loop” it resets to 0… hence the 1 turn twist when that happens - and that twist will always be the same size as your curve resolution where the “reset” happens. You’d need to keep track of how many turns your custom normal has made and add that (in units of…

Looks like you’re attempting an intersect bevel - That’s not something I’ve managed to achieve (tried and failed). A general solution is beyond my current capabilities, so I would try maybe fake it with a circular pofile? Donno.

Will make another attempt at solution sometime but can’t promise anything. 🤷‍♂️

Sorry for unsatisfactory answer.

Good luck.
