You could try ShapeMap

You could try ShapeMap plugin. It is very powerful. I reused ShapeMap example and @jonahhawk script to make the pattern [image] ShapeMap 0.72 sample Traingle Perf.gh (408.1 KB)

Here are a couple of ways:

The first (top) one doesn’t ‘map’ it, instead it trims your hexes to a ‘thickened’ version of your trimmed surface. The second (bottom) does a mapping of the curves via MapSrf - both look good but they’re slightly different.

The “easy way” is Map Srf (purple group) but it gives the same result as you already got the hard way (sincere congratulations on that). The other way is TriRemesh ‘D’ output (white group). Both require trimming of face boundaries, as your method does.
