Model elements describe the artifacts of software development and add semantics to models. You can add, modify, sort, group, and filter model elements.
Copying and moving model elements
You can copy or move a model element to another model or model element. All the model elements that the selected model element contains, including relationships, are copied or moved along with it.Deleting model elements
You can delete a model element from a model.Sorting model elements
You can change the sort order of the model elements in your model.Filtering model elements
You can filter the model elements that are displayed in the Model Explorer view so that you can see only those that you want to work with.Organizing model elements into packages
You can use a package to organize model elements in a model. Packages can contain any kind of model element, including other packages.Documenting model elements
In UML modeling, you can add detailed information to the model elements in your models. This text could include any information that you want documented, such the role, purpose, or behavior of the model element.Linking model elements to external files
In your UML model, you can link a model element to an external file, such as a Microsoft® Word document or a graphic file. This link is useful if you want to provide more information about a model element.Using stereotypes and constraints to extend the meaning of model elements
Stereotypes are applied to model elements to identify their purpose and extend their meaning. Constraints are applied to model elements to identify a condition that a model element must satisfy or a restriction on a model element.Examining the inheritance hierarchy of classifiers
In UML models, you can browse the inheritance hierarchies of classifiers that support inheritance, such as classes, interfaces, and use cases. Using the Inheritance Explorer view, you can view the subtypes and supertypes for a selected model element, as well as the corresponding attributes and operations.
