There are several ways available to get at individual elements in a list or to extract subsets of data. One of the easiest methods is to use a Split component. This component breaks a list of data into two sublists at the specified index.
1.Create a grid of points using cross-reference
2.Split the list into two using a slider
3.Create boxes with varying properties using: surface > primitive > centre box
This exercise is using Grasshopper version 1.0.0007
