Selecting only the edges of the voronoi?

[caskal]

Hello community, I'm trying to select (end-unroll) only the edges of a voronoi, is this possible? I tried with a divide sop (remove shared edges) with no luck, what I want is get the borders only of the voronoi coloured pieces, not the quads that are inside each piece, in other terms clean the mesh and have only the voronoi divisions and unroll them.

Thanks!

blast the 'inside' group -> divide 'remove shared edges' -> ends 'unroll'

@mestela you are the man! this was driving me crazy, thanks a lot! 

Btw great article on Gridmarkets!

Thanks!!

Hi @mestela, this solution is great! Would you mind explaining, how come creating an inside surface, blasting them and removing the shared edges end up outputting only the voronoi edges?

I'm trying to understand the logic behind it as the topology of the previous node (grid) is combined with the newly created voronoi edges and i would like to get the idea about how your procedure removes the previous topology but keeps the voronoi edges.

 

Thanks!

i would have thought it's like this, unless I'm reading the problem wrong...

(Mestela's way is losing the inside details ? but as said, I could be not understanding the problem 100% tho)
