I think I am close to the definition I want but I cant quite figure out the last step. I have custom geometry that I am using in an attractor across a hex grid. I cannot figure out how to contain the hex grid within the bounding box rectangle? Whenever I resize the grid it resizes on its own and goes beyond the rectangular bounding box.
I would like to have the scallops become more crammed within the rectangle when I increase the size of the hex grid, rather than having the hex grid grow with no relation to the bounding box.
Hopefully this works for you, I am using Rhino 6, but it looks like you are using R5.
Instead of using the hex grid you have, I used the Hexagon Cells component from Lunchbox. Of course it is possible to make your hex grid work, but I think this is a simpler option.
