Local areas on a hydraulic or pneumatic diagram are typically outlined by what?

In hydraulic and pneumatic diagrams, local areas are often delineated using a specific pattern of lines, which can include a sequence of dashes and spaces. This visual representation assists in clearly signaling different sections or zones within the system, allowing for easy identification of functional areas or components. Such a designation is crucial for maintenance and troubleshooting, as it provides a clear boundary that distinguishes between various elements of the system.

Using this method of dashed and spaced outlines helps convey important information about the areas being depicted without cluttering the diagram with excessive detail or competing visuals. The visual nature of this representation makes it easier for technicians and engineers to interpret and navigate the diagrams efficiently.
