Uniform… and also ordered? The pores in your cube are placed in a grid…
“this”? … what do you mean with that sentence? You want to make pores over a brep/polysurface? Is that cell element a pore? Please be specific. Explain better, please.
Generally speaking, i would use “Populate geometry” to get some raw point, then use “Sphere collide” with kangaroo to make them uniform, while the points are kept on the surface with “OnMesh” or similar.
Then with the output of kangaroo, make brep closest point, create a plane from the point+normal, orient your “pore cutter” and do a solid boolean on your geometry.
