Graphical representation of objects, connections, and free-form texts.
It is used to represent items in a model.
With an occurrence copy, several occurrences of an object can be created. These can differ within a model and/or in different models, that is, object symbol, size, color, and attribute placements can be set individually and thus be different.
If the placed text attributes of an occurrence are changed, the changes are applied to all occurrences at which the text attribute has also been placed. For example, if the name of an object is changed, the change is displayed for all occurrences.
