Sorting geometry is extremely common in GH and there are many ways. In this case, Isotrim avoids the need for sorting (purple group below). But if SrfSplit is required, you can sort only by X and Z as shown in the white group. The expression on pDecon ‘X’ is x*1000 which, of course, is very specific to this data set.

P.S. This demonstrates how Isostrim (SubSrf) still works while sorting by X and Z (white group) gets messed up. It could be fixed by using distance from surface edges but that’s complicated!
