Using ArcMap 10.1. Lets say you have 100 polygons that all are in the exact same shape and in the exact same place. They appear to be one polygon. How would you edit the shape of all 100 at the same time, can you share vertices among the 100 polygons? Can you join all 100 and keep their separate attributes and Object ID's?

I think you can try Editing shared geometry and Reshaping a topology edge. (Also #10 here)

None of the polygons are Topology. They are in a geodatabase, feature class, polygon. – Jason Campbell Oct 27 '12 at 1:05

Are you talking about duplicate polygons that you want to remove it ? – PROBERT Oct 27 '12 at 3:27

Map topology can be based on any feature classes. You need to create topology manually for your polygons, read this Creating a map topology – nadya Oct 27 '12 at 4:41
After playing with the Topology tool, I am amazed that I haven't used this before. This is what I was looking for dealing with stacked polygons! Thanks nadya – Jason Campbell Oct 27 '12 at 22:29
