Connect Nodes (Interface) 

The Connect Nodes (Interface) command is available in Base Schema v70 or earlier that contains the Interface class. It is accessed on the Diagram ribbon and opens a connections window on the selected node to show any current interfaces. From this window you can edit existing interfaces or create new ones.

 

 

The variants of block diagrams (interface block diagrams and internal block diagrams) all represent connectivity between components. In the case of these diagrams, the lines connecting two nodes actually represents a logical interface. This differs from most diagrams where lines simply represent relationships. Therefore, the connections dialog offers additional power when connecting a node.
