Been very active contributing to the geometry nodes discussion on BA and only stumbled across this now… You may want to add the geometry-nodes tag to this thread to make it more visible.
Anyway, useful groups here:
- curve-to-chain-link-fence
- z-curve-sweeper-for-blender-3-0+ (Packs everything below)
- curve-to-mesh-with-even-thickness
- z-up-curve-tilt
- z-up-curve-to-mesh
- curve-to-mesh-with-uvs
- disconnect-cyclic-curves
- split-splines (Vertex Split for curves)
