Actions Available in the Diagram Editor

The contextual menu offers the following actions:

Show only the selected component
Depending on its state (selected/not selected), either the selected component or all the diagram components are shown.
Show Annotations
Depending on its state (selected/not selected), the documentation nodes are shown or hidden.
Auto expand to references
This option controls how the schema diagram is automatically expanded. For instance, if you select it and then edit a top-level element or you trigger a diagram refresh, the diagram will be expanded until it reaches the referenced components. If this option is left unchecked, only the first level of the diagram is expanded, showing the top-level elements. For large schemas, the editor disables this option automatically.
Collapse Children
Collapses the children of the selected view.
Expand Children
Expands the children of the selected view.
Print Selection
Prints the selected view.
Save as Image
Saves the current selection as image, in JPEG, BMP, SVG or PNG format.
Refresh
Refreshes the schema diagram according to the changes in your code (changes in your imported documents or those that are not reflected automatically in the compiled schema).

If the schema is not valid, you see only an error message in the Logical Model View instead of the diagram.
