I created a service area of multiple facilities and as a result I got a feature class with multiple overlapping polygons of the same value.
To merge all these polygons I tried to use Dissolve tool using "Travel Time" as a dissolve field, however the output of the Dissolve tool is represented in ArcMap as just a single polygon, even though attribute table looks like this ("ToBreak" is in minutes and correspond to "TravelTime"):
I tried to check/uncheck "Create multipart features" option, but result was always the same. Also when I switch the Dissolve output to hollow symbol, I can see boundaries of merged polygons. Am I missing something? How to merge overlapping polygons?
