Delete from Model

A given model element may appear in more than one diagram. Thus, when you delete it from one diagram, it may still appear in other diagrams. The Delete from Model command on the Model menu will delete an element from every diagram in the model.

If you erase one or more elements from a diagram and all of those elements only appear in that diagram, those elements will be deleted from the model automatically. But if the erased element appears in other diagrams as well, you will see the Nodes Deleted dialog:

In the top half of the dialog is a list of all of the elements that you erased. Check the box in front of each element that you want deleted from the model as well as erased, and then click OK.

In the bottom half of the dialog, you have four options to choose from:

• Always delete from the model: Choose this option, and Tablet UML will always delete from the model, without displaying the Nodes Deleted dialog.
• Delete from the Model if the Item Appears in No Other Diagram: Choose this option, and Tablet UML will attempt to read your mind: it will automatically delete from the model if you erased the only instance of the element, but will not delete if the element appears in other diagrams.
• Never delete from the model: Choose this option, and Tablet UML will never delete from the model, and will not display the Nodes Deleted dialog.
• Always ask before deleting from the model: Choose this option, and Tablet UML will continue to display the Nodes Deleted dialog when needed.

You can also change the deletion rule via the Tools Menu.
