optimize a mesh

Hi there!

I'm struggling a bit with the conversion surface->mesh. Since I am quite new to Gh (and since I've never had the real necessity to convert a surface to a mesh) I don't know which parameters I have to change to improve or to obtain a clean mesh from a surface (the tool "Mesh Brep" doesn't appear to work very well without custom settings)

You can find a sample definition I was trying to optimize (in vain).

I would greatly appreciate any help you can give me!

Thank you ;)
Matteo

Thank you very much Daniel!

So, just in order to understand the basic principle behind this, basically is always better to create a mesh from vertices rather than from a surface, right?

It always depends of the geometry and the result you want.
In this case it's best to do the simplest method (in sense of minimizing the number of points and faces). Due to you have a trimmed surface, with many irregular holes, do not serve MeshBrep to do a clean mesh.
The wrap a Voronoi diagram is a typical exercise, there are plenty of examples of this here, also with voronoi3d. ;)

Sorry if I'm annoying you again with silly questions.

I tried to apply the same definition to a 3d voronoi, but for some unknow reason (at least, for me :D ) it doesn't work. It seems that the mesh can't be created because there are "insufficent vertices for a mesh". Can you please take a look and tell me where I went wrong?

Thanks a lot!

The reason is that the Explode components returns branches with lists of different sizes, due to make the intersection two times, rather than doing it once and scaling.

But with Voronoi3D, I meant (see attached)
