Asteroid

I tried my hands at the smoothing and simplify polygon tools as well apart from the normal approach. All are in the file attached. The solution is the flow at the bottom.

I started out with the Poly-Split tool, but had to confront the helpfile in order figure out how Split:IsHole was working

The Area of the split objects is easy found with with the Spatial Info too, and from there we can find the needed objects using a filter,

Last thing is to combine the filtered split objects, and here the  Summarize tool never fails to amaze me by the diversity og objects it can be used on.

Does anyone know if there is a benefit to adding the Spatial Info tool with Number of Points selected before the Split to Detailed Regions step? I didn't use that functionality, but got the same ending answer and total area...
