To create an abstraction, drag-and-drop the Abstraction shape from the document stencil onto the model diagram. The Create Abstraction dialog is displayed:
A name for the abstraction must be specified. It can be up to 20 characters in length of mixed case, and must be unique within the model.
Click the OK button to create the abstraction. Its shape will be updated with its name on the model diagram.
Note: If creating an abstraction when another abstraction is active, the new abstraction will be automatically added to the active abstraction.
If you do not wish to create an abstraction, click the Cancel button.
