Voronoi 3D
First using Pop3d to generate a point cloud in a setted box
Then use Voronoi 3D to generate volumetric diagrams from the point.
Break the brep and make the surface boundaries, flatten the surfaces.
then deconstruct the brep again, use the verticles to create interpolated curves and adjust the sizes using area and scale
Finally use the surface spit to create the skeleton you like.
