This is an elastica curve. This GH code shared by Daniel Piker might be helpful:

Elastic Beam Bending

Hi Kieran, Yes - finding non-planar elastica curves is quite easy in Kangaroo. I believe the approach in that old forum post is specific to the planar case. Here’s a simple setup that takes a curve, fixes 2 points at either end to keep the tangent direction, and relaxes to find the elastica: spatial_elastica.gh (16.7 KB)
