# Homogeneous hole pattern in the surface of a geodesic dome

So, I am still fighting with the porous spheres. I managed to create the holes in every single face of the icosahedral sphere (geodesic dome), however when doing the inset faces (I) and extruding inside, I should see a similar pattern of hexagon holes...instead of that, I observed also irregular pentagons and other weird figures. I understand that in order to complete de perfect sphere, pentagons play an important role (like a soccer ball), but is there any way I could have exactly a similar pattern of holes?

This is the sequence of commands I conducted:

1. Added geodesic dome

2)Inset FAces (I)

3)Extrude (E)

4)Bevel

Any idea? Thanks

Edited: I would like to have something like that. No matter whether using hexagons, pentagons or whatever

I should have made this an extension to the original answer.. but here goes.

Activate the shipped add-on Loop Tools

After making the I Inset > Individual, use Loop Tools > Circle on all the selected faces, with a 'Radius' set. It's wise to estimate the desired radius before invoking, in this case; the operator is Python, and can be a bit sluggish.

The result will be slightly irregularly distributed holes, (as you noted, you can't tessellate a sphere with hexagons), but they will all be the same size.

Or.. you can Shift G select out the pentagons, and make those holes slightly smaller..

Or... you could use the same Loop Tools adjustment, on a different topology.
