This Geometry Nodes setup generates complex, multi-layered nested cables where larger outer paths enclose smaller internal strands. The procedural system automatically packs the internal structures to prevent overlapping and collision collisions between the wires.

Users can customize the number of external cables, set profile mesh resolutions, and apply twist or tilt based on the curve length or factor. Adjusting the base radius automatically scales the internal cables to fit correctly. The tool outputs multiple custom attributes directly to the Shader Editor, providing zero-to-one gradients for specific layers, index gradients, and randomized values for flexible material assignments. In Blender 4.0 and above, the setup utilizes the Repeat Zone to allow for a customizable number of structural layers.
