Schematic View is a window that lets you see everything in your scene as a node on a graph. The nodes are repositionable to create custom configurations.
Use Schematic View to see and select all nodes that share a relationship, such as a material or instanced modifier. You can perform basic operations on the nodes such as rename, cut and paste modifiers or materials, or create hierarchical linkages. You can use Schematic View to see and edit other relationships such as wired parameters and constraints.
