Asymptotic Curves on Surface not clean Bowerbird

Hello Forum.

I’m working on modeling asymptotic curves/strips using Bowerbird on a Lunchbox Enneper surface, and I have two main issues:

  1. I’m not sure why the resulting curves aren’t coming out clean—they appear wavy and irregular. (1)

  2. When I extend the curves along the surface, they don’t align correctly or follow the geometry as expected. (2)

Any insights or suggestions would be greatly appreciated!

rebuild the surface solve some percent of the issue

Hello. I know I’m very late but thought I would mention something as I am going through the same issue. The problem is with the accuracy of the LunchBox surface (not their fault, it’s good enough for most situations and there is of course a seam with a uv surface.
You could have a go implementing a set of parametric equations yourself to generate a new surface perhaps? See below for the Enneper-3.
