Schematic views are a place to work with your objects and visually see as well as edit their parameters and relationships. Schematic views are for working with Objects, Materials, Lights, Cameras, Effects, Particles, Controllers and everything that exists in 3ds max. They can be used to visualize and adjust hierarchies and other relation ships such as wires and custom attributes. In a schematic view you can "wire" in any one value from an object parameter or modifier to another Object, Modifier, or Material in 3dsmax. You can also implore the use of Expressions, and Maxscripts to further extend your setups.
