Steps

Create behavioral ports

Review the sequence diagram and identify messages exchanged between lifelines. Define behavioral ports on each structural block for incoming/outgoing messages. For more information, see Guideline: Service Request Driven Modeling Approach.

Create interfaces

Logically group messages in Interfaces. For more information, see Guideline: Service Request Driven Modeling Approach.

Associate interfaces with ports

Associate interfaces with ports. For more information, see Guideline: Service Request Driven Modeling Approach.

Connect ports

Create connectors between the actor blocks and the relevant use-case block ports to support communications defined by the interfaces.
