How to change the pattern of one piece only

[@gullibleboar3511]

when I increase the number of seeds, the holes in the drawing do not increase. How can I increase or decrease the texture? always for the same dimensions

[@RhinoGrasshopper]

You need to increase the number in the 'populate 2d', not the seed.

Hi! At the minute 10.15 you connected Data dam with Surface split. I tried to do this operation but it appears one error with red at the Surface split: "Splitting returned no results". Do you have any idea how to solve it? Thank you in advance.
