voronoi on surface problem

Hi, all!

I try to attach voronoi pattern on surfaces. I create random points on a surface and then use "voronoi cell" to intersect with the original surface, and successfully create the pattern. But each of the curve I create could not be deconstructed by "deconstruct brep". And strangely enough the perfect curve pattern couldn't make perfect tubes, I would like to know why.

Thanks!

Get this for the moment (Plan B is for the very brave, he he, if it works at all)

BTW: going from that state (Plan A) to a perfectly "fuzed each other" (in nodes, that is) collection of pipes is NOT a task for a novice.

PS: added a filter (option 3 works) in case that you want to play with Plan B:

This is what it could(?) been(?) done(??) with meshes but only if that ExoW ... wasn't ... er ... hmm ... "temperamental"

he, he

Hi, Peter!

Sorry I have to digest for a while and I do feel lucky.

First I don't quite understand where "I'm brave", and second I don't know what are Explode and Stream Gate working for, why after Explode there's no unwanted joints anymore.

I try link Pipe after Explode, and it seems to me no difference with linking after Stream Gate. I admit I'm a absolute freshman here, and could you help explain why "deconstruct brep" can't work with the curve even in your file?

Explanations inside file (search this forum about what Brep (boundary representation structure) is).

Other than that ... the gate in the yellow group redirects data to ExoW (which is missing from your arsenal > search Forum "ExoW" > get it > and download again the V2). ExoW is "tricky" mind.
