@DanielPiker can you help me

Here’s an example

conefold_example.gh (11.0 KB)

We use Length goals to keep the edge lengths fixed, and a Coincident goal to pull the ends of the opening together.

Because everything starts in one plane, we also need something to initiate the buckling out of this plane, so there’s a ‘nudge’ part which allows you to momentarily apply a vertical force to the central vertex.

for this case is there any way to do @ ? actually when connecting 2 red lines, it will form a curled strip, how to simulate such results? can you help me, i tried to rework from your gh file but this doesn’t work.
