I am using ArcGIS 10.3 for Desktop.
I am working on a map that I have divided into 5 zones. I have drawn 5 polygons to represent each zone. I need to align the polygons where the edges meet. I am trying to use the "Align Edge" tool in the Topology toolbar. I select the tool, click an area of one polygon where there is a sliver I need to remove. I see a dotted line and then click the other polygon where I want the edges to align.
I get an error message that reads:
The edge cannot be modified. The operation was attempted on an empty geometry.
I don't know why this is happening or how to rectify.
