4.4.4.4 Port Nesting
Ports indicate possible connections to other objects according to specified system types, flow direction, and connection properties. Ports are typically connected between devices via cables, pipes, or ducts.
Ports may have placement defined indicating the position and outward orientation of the port relative to the product or product type. Ports may also have material profile sets defined indicating the flow area and connection enclosure.
The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the tables below shows a recommended list of general usage patterns that users may adopt.
