What is the action required to view the service perimeter within the diagramming tool?

To view the service perimeter within the diagramming tool, the correct method is to click "view" on the top toolbar. This action directly accesses the visual elements of the diagram, allowing you to see the service perimeter and how it relates to other components of the layout. The toolbar is a primary area of interaction within the tool, where users can make adjustments to their view and access specific formatting and visualization options.

Options referencing a 'view tab' or 'service options' may imply actions related to general viewing or settings adjustments, but they do not specifically direct the user to the correct functionality for displaying the service perimeter. Additionally, opening the settings menu typically deals with configuration rather than a direct visual overview, which can often limit the user’s ability to see the current layout as designed in the main workspace. The placement of options within the top toolbar makes them more intuitive for immediate access to key visual features, emphasizing why that choice is the correct path to take.
