Deleting components
When you delete diagram components, you can choose whether to delete them from both the model and the diagram, or from the diagram only.
To delete components:
1. Select one or more components.
2. To delete the selected components from the diagram only, press the Delete key.
3. To delete the components from both the model and the diagram, press Shift +Delete.
Note: You cannot delete the base component of the diagram. You can delete only those elements that you add after creating the base component.
