I have an issue where I have feature classes of groups of zip codes in different sectors of the US that I have created. I want to be able to define the outer boundary of these groups so I can create a single shape file (one polygon). I was going to use this new polygon to clip the original file.
Is there a way to take many polygons and create a file that only shows the outer extent of the group? And how would I go about such an endeavor?
