I'm working on a series of maps which divide up an area into sections. Each section is drawn as a polygon, and most of the polygons share a border with neighboring areas.Some of the borders are quite complex and take a long time to create. I'm wondering if there is a way to copy one polygon, paste it into the exact same location on another map file, and easily delete all points that are NOT on the shared border. (Easy in Illustrator; don't know about ArcMap!) This would ensure that the neighboring borders match exactly, and would save the time of redrawing the common borders.
Additionally -- some of the areas will share borders with more than one additional area, so the question becomes a bit more complex. Suggestions appreciated.
