Delete relationships
An Edit menu and right‑click symbol menu entry is available which allows the selective deletion of Relationships. If one or more node symbols are selected, the menu entry reads:
Delete relationship(s) for selected symbol(s)
System Architect will delete all the Relationship lines attached to the selected node(s). Any selected Relationships are not deleted except when they are attached to one or more selected nodes.
