Overview

A connection, an item of the CONNECTION class, is a graphical item that creates a logical relationship between two, or more, objects. You can use connections to represent almost anything that provides a pathway or route between two or more objects. For instance, use connections in your knowledge base (KB) to represent electrical wires, pipes, roadways, or cables.

The next figure shows several connections between various objects on a schematic.


In addition to representing physical entities such as pipes and wires, connections can represent more abstract relationships such as the cause of one event by another, or one event occurring later than another. A connection can also represent a transition from one state to another.
