Trying to replicate pattern

[Geoffrey_deClouet (Young_grasshopper)]

Hi there,
I am trying to replicate this pattern (circular Google product)

as a debossed grip texture on this surface (Gray Squircle)

Uploading: C2-Clean Surface-Dot Pattern.3dm…
. I have found several tutorials on square grids, but nothing on circular alternating grid patterns like in the example. Any advice you can give would be helpful!

Thank you

Gradient Dot Pattern

Your radiused rectangle in this thread is 749 units long compared to 595 units in the previous thread (and my last post). And the corner radius is smaller. So more holes (400) works better than 141 holes. And it looks better to reduce ‘Min Radius’ from 0.429 to 0.250. [edge_holes_2021Oct27c] edge_holes_2021Oct27c.gh (51.4 KB)

Map Curves to Surface

Added a “gutter” slider (blue group) to inset the outer ring of circles, added cut holes (orange group, SLOW!), adjusted some parameters slightly. [edge_holes_2022Sep22b] edge_holes_2022Sep22b.gh (104.8 KB)

@Joseph_Oster solution must work well for what you want but I just wanted to play a bit with that. So here are 2 ways

• UV curves, you need a Surface as input
• Tweens curves (need Nautilus and Pufferfish plugin). UV must work without plugin. Tweens curves is a bit more generic as it requires a mesh
  I choose to take maximum radius possible. So along a ring radius is not the same.

And a version that just uses a mesh and Nautilus plugin to draw the perpendicular curves of tween curves

Also possible to make a sort of diagrid curves and then use the intersection.
