arcgis desktop - Displaying adjacent polygon lines beside each other instead of overlapping

I would like to display adjacent polygons with the line work beside each other, not one on top of the other for that shared boundary. I do not want to edit the polygon boundaries - only want to change the way they are displayed. Is that possible?

Answer

This drills down a few dialogs, but it will do what you want

When symbolizing your layer, pick a polygon style that is close to what you want.

Select Edit Symbol ... in the Symbol selector dialog

Select Outline ... from the Symbol property dialog

Select Edit Symbol ... from the Symbol selector dialog

Change the Type to Cartographic Line Style and select the Line Properties tab in the Symbol property editor dialog. Enter a negative offset and OK out through the dialogs.

You will need to play around with this a bit to get it to appear the way you want.

I would save it as a style once you have it the way you want it.
