How are service area polygons generated in ArcGIS Pro?
If no value for the Breaks_ [Cost] field is specified, service area polygons are generated for the facility based on the Cutoffs setting. Together, these properties describe the point on the network where the object is located. The CurbApproach field specifies the direction a vehicle may arrive at and depart from the facility.
Which is truer service area lines or polygons?
Lines are a truer representation of a service area than polygons since the service area is based on measurements along the network. Service area lines are not generated by default during a service area analysis; you can choose to generate them.
How is the name of a service area determined?
The name of the service area polygon is based on the name of the associated facility and the break range; for instance, Graphic Pick 1: 0.0 – 5.0 would represent a polygon that covers all traversable edges within five minutes from the facility, Graphic Pick 1. The unique ID of the associated facility.
Where do I find the service area analysis layer?

How are lines generated in service area analysis?
The Lines feature class doesn’t provide any inputs to the analysis layer; it serves to store outputs only. Service area lines are not generated by default during a service area analysis, but you can choose to generate them. On the Service Area tab, in the Output Geometry group, set Output Shape Type to Lines or Polygons and Lines .
