Dividing UML models into fragments

UML models can be large and complex, particularly in team environments where the models are shared and edited by different people. To make it easier to work with a large model, you can save portions of the model as fragments, which are subunits of the model stored in separate files.

About this task

Each fragment is saved as an EFX file. Fragments can contain cross-references to other fragments, and if they are no longer required, can be moved back into the parent model.
