I'm wondering if anyone knows a method in Illustrator to create non-duplicating lines out of areas with shared edges. Image areas of each state in the US and you want to create just a set of lines for the borders without the duplicates.

There is a function in the Pathfinder menu for that, but I forget exactly which it is. Its easy enough to experiment but Im sure someone will chime in with the actual tool.

It's the outline tool, 2nd from right on the bottom row. It'll replace shared edges with a single one. Keep in mind it makes a group of the output and removes fill and stroke.
