Review Preserved, Temporary, and Free Nodes

Use the Preserve Node Panel to review the preserved and temporary nodes in your model.

When you open or import a model that contains preserved nodes, you can only review these nodes in the Preserve Node panel.
Open the Preserved Nodes panel to review preserved, temporary, and free nodes.
Preserved nodes are automatically highlighted red, and the number of preserved nodes in your model is reported in the bottom-left corner of the panel.

Temporary nodes and free nodes (nodes that are not referenced by any entities in your model) are automatically highlighted yellow.
