Using anchor nodes

You can specify that an element in the diagram is a root element by setting it the element as an anchor node. Click Set Anchor to set or unset an element as an anchor node.

Note: A diagram should have at least one anchor node, otherwise the diagram will be empty.

• To set anchor nodes on multiple elements, select multiple elements and click the Set Anchor command.
• To unset anchor nodes on multiple elements, select multiple elements that are anchor nodes and click the Unset Anchor command.
• If you hide an element that is an anchor node, all associated elements that are not anchor nodes will also be hidden.
