Brep on this GH algorithm (Voronoi Generation on shell structure surface)

Have a try dendro plugin. It’s faster than Cocoon

Dendro

Scaling Surface composed of Multiple Faces - Voronoi Skeletal Mesh

You didn’t internalize your base geometry nor posting your 3dm, so the file you posted has been useless for now… Anyway, you can make intersection curves by using MMX or BBX depending on your type of base geometry. And you could do curve thickening by using plugins like dendro. In the attached def, I used subD as a base geometry by using the multipipe command in R7 [Canvas at 16;22;23] Thickened 3DVorinoi_re.gh (27.7 KB)

3D voronoi

Here’s a more dense voronoi sphere with dendro plugin. Using Topologizer together will helps dendro work successfully. [Canvas%20at%2019%3B12%3B26] VoronoiSphere_re.gh (12.2 KB)
