About the 3D Graph View
Use the 3D Graph view to navigate the parts of a 3D model and to show and hide the parts from view. With the Transform tool selected, you can select a subnode from the list to see it appear highlighted in the Camera and Perspective views. Use the arrow keys to quickly scroll through the list.
The 3D Graph view also allows for the set-up of animating parts of the 3D model, as well as linking 2D drawings to the movements of a 3D model's parts.
