Show, hide and filter model elements in the diagram

While viewing model diagrams in the Architecture tab, you can navigate the hierarchy of models. As you navigate, you can use options to hide and show (expand and collapse) child and parent elements as well as hide and show trace links and connections.

Procedure

To show or hide model elements, click the Visibility Control and choose from the following options:

If no model elements are selected:

• Fit — Fits all the model elements in the diagram.
• All Off — Hides all the model elements in the diagram.

If model elements are selected in the diagram:

• Fit — Fits all the model elements in the diagram.
• Fit Selected — Fits only the selected model elements in the diagram.
• All Off — Hides all the model elements in the diagram.
• Selected Only — Shows only the selected model elements in the diagram.
• Selected Off — Hides the selected model elements in the diagram.

You can also show and hide model elements by selecting model elements from the Content list on the left hand side and using the Visibility Control.

To filter relations, click Relation Filters. By default, connectivity, traceability, and occurrence traceability are supported. You can select multiple filters and the applied filters appear in the diagram. The Relations Legend panel also maps to the filters applied.

Click Relation Controls. Click the arrows inside the relations box to expand or collapse the incoming and outgoing relations:

• Click to show all the incoming relations.
• Click to show all the outgoing relations.
• Click to hide the incoming relations for the object.
• Click to hide the outgoing relations for the object.
• Click to hide all the incoming relations or show all the incoming relations. This button appears when incoming relations are partially shown in the diagram; clicking it asks whether to hide the visible incoming relations or show all incoming relations.
• Click to hide all the outgoing relations or show all the outgoing relations. This button appears when outgoing relations are partially shown in the diagram; clicking it asks whether to hide the visible outgoing relations or show all outgoing relations.

These commands only expand or collapse the connections and relations, not the objects in the diagram.

(Optional) To hide individual model elements, click the icon on the model element. The model element fades and then turns off. You can stop the model element from disappearing by clicking the icon again. Any children associated with the block are also hidden as well.

You can also hide and show model elements using Relations Controls.
