How to change the thickness of this model

I have created this model with grasshopper but I am still pretty new to it and don’t how a lot of it work

By “change the thickness of this model”, do you mean the thickness of all the surfaces? (or “Faces” returned from Deconstruct Brep ‘F’ output?)

Many try but as far as I know, there is no facility for that in Rhino/Grasshopper. You can thicken each of those faces separately but the integrity of the “Closed Breps” (solids) they come from will be lost.

Or do you mean increase the Scale factor from 0.5 to 0.95 (for example)?

I noticed a few things about your model I would have done differently so modified it.

  • You don’t need to create the spheres twice, you can use them for two different purposes, SUnion and Scale.

  • Plane Through Shape (PxS) will work as a cutter instead of Circle with no need to specify an arbitrarily large radius.

  • It is faster and simpler to use SDiff before SInt with the Voronoi³ cells.

  • Random and Reduce need ‘Seed’ sliders with a range of 0 to 300.

Result is the same as what you had, just a little faster. (25.0 KB)

I mean the thickness of all surface to make it a bit more thinner

Does that mean increase the Scale factor from 0.5 to 0.95 (for example) ?

But the same scale applied to all spheres will result in different thickness because they all have different radii. You can calculate a different scale factor for each sphere so all have the same thickness like this (white group): (28.3 KB)

The faces of each of these closed breps have no thickness at all, they are “surfaces”.

Would the increased scale make the model thinner? if so then yes

I suggested that in my first reply. Have you looked at the last GH model I posted?

I’m looking at it now, thank you for the help

Why would you respond without first looking at what I gave you?

Did you write this code or just find it somewhere?

Because I didn’t understand what you meant
