Lofting Curves in Geometry Nodes in Blender 3.6

Freeform parametric wave bench render over the words

I've seen a handful of tutorials on lofting curves in Geometry Nodes and I think they all miss a trick. More often than not, you don't want to just wrap a mesh to the points of your curve and be limited by your curve topology - that's not using proceduralism to intellegently add complexity.

In this tutorial, I'll walk you through creating a Loft Curves nodegroup with independant U and V resolution controls as well as a switch between linear and smooth (Catmull Rom) interpolation. Additionally, we'll actually use the tool to build a parametric wave bench and in doing so learn about correcting flipped curves and sorting things by world position rather than relying on alphanumeric naming.

As usual it's a few lessons packed into a single exercise but these are very broadly applicable workflows so I hope you enjoy!
