Design Objects with Connections refers to design object that have been connected to other design objects. Connections are established between design objects using a combination of Object Connection Types and Class Relations. Object Connection Types can be defined for a class in Class Relations to relate it to another class. e.g. Defining the can drive object connection type for the MOTOR class, in turn defines the can be driven by object connection type on the PUMP class and establishes a class relation between these classes. With this class relation in place, design objects of the PUMP and MOTOR classes can be connected via the appropriate object connection type.
