This activity is used to define the class relations which determine the relations between classes. This in turn determines the relation and connection possibilities between a design object and another design object, a design object and a design part, and a design part and design part. Class relations need to be defined separately for Design Object and Design Part Classes.
An organized class relation scheme simplifies the plant registration process by limiting the number of relations that appear in a list of values and indirectly helps to ensure that only reasonable relations can be made. For example, when registering a transmitter, the only possible free functional parent relation to select from would be an instrument loop.
