Offset problems on voronoi pattern with MOI3D v3

Hi !

I'm using MOI3D to work with Voronoi pattern created by Processing scripts. The problem I have is during the offset process, I get several curves I can not merge later. I tried to create inner offsets, but it doesn't work. I have also tried union boolean of the different curves, but without any luck. All I can do is creating outer offset with Voronoi cells conteing several curves I can not merge:



I would like to have this result:



How can I get some clean Voronoi cells in my construction ? Do I need to use external softwares like Illustrator ?

Thanks by advance for your help,

Pierre
