I need to ensure that the polygons created are in ascending order from the first polygon which is known or can be found. I think there is a transformer in 2018 that can do this but I am using 2016. I have tried using NeighbourFinder and sort by ascending distance which is OK as long as the polygons do not turn back towards the first one.
Question
Ordering polygons created by splitting one polygon into multiple polygons.

Could you describe in a bit more detail, how you are splitting the polygons, and what you mean by "do not turn back towards the first one".

not sure as well.
..still I'll try
Use a NNF to project the centre points of the polygons to the border of the Hull of the polygons (create vertex on candidate or use close candidate x and y).
Get the points (chopper) PointonLine overlayer.
Then output of PoLo to a topologybuilder, points will then be ordered.
Or maybe the little ordening expression is of use to you. It is posted somewhere in this vast forum.
