Asymptotic Curves End Condition

Hi all,

First time diving into the interesting topic of minimal surfaces and asymptotic curves. I’ve managed to use the Bowerbird Pathfinder component to generate asymptotic curves on a Hyperbolic Paraboloid. However, the curve end conditions are strange to me (not smooth jump). Is this a function of accuracy or am I missing something obvious? Maybe it’s only visual?

Eventually we want to explore using timber to create a gridshell, similar to the work of Eike Schling ( Asymptotic Gridshell | Eike Schling).

Thanks all!

I imagine it could be tolerance related or the surface itself. You could try to discard possible cuases.

Thank you. The surface was generated through the Lunchbox plug-in. I tried adjusting the Bowerbird tolerance. It’s strange - at the locations circled above, there are actually multiple small curves. The main asymptotic line “breaks” near the boundary conditions

Did you try to generate a surface with the kiwi plug in? Its also from the TUM guys, I think they are mainly using it for their asymptotic stuff.

This may be related

Bear in mind that a hyperbolic paraboloid is not a minimal surface!
It is similar but not identical to the minimal surface on the same boundary.
The only ruled minimal surface is the helicoid.
