Hi there,

I’m trying to number these points by row rather than by x value so that a cull pattern might work more regularly. When I flatten the list - the default renumbering goes in the x direction however I want it to number down by row.

Thanks in advance,

This is doable but how did you create all these surfaces?

Thank you!


Created a rectangle of paver size required then rotated and array-ed linear.

When you flatten a tree, you loose it’s structure. But it’s all there. All you needed to do is flip the matrix.
