I have created a road network dataset, loading my facilities, and am running network analyst to identify services areas.
Polygon Generation for all versions is set to Detailed,Trim, 100 meters, Merge by Break Value, Disks.
For some reason, if I ask for one specific break, I get a different polygon generation than if I had done multiple breaks.
Both lines showing are the 7 minute break, so it's not a matter of choosing the wrong break.
Any idea as to why the service area would change if I specify a single break versus multiple breaks and only showing one break from that group?
