Chapter 25: Working with the Schematic View
The Include in Calculation section includes options for limiting the following:
l Base Objects: The geometry type that makes up a node. The node is the named object, such as
Earth; the Base Object is its primitive, such as Sphere (Object).
l Modifier Stack: Identifies all nodes with modifiers applied.
l Materials/Maps: Identifies all nodes with materials and maps applied.
l Controllers: Identifies all nodes that have controllers applied.
l Static Values: Displays unanimated parameter values.
l Master Point Controller: Displays nodes for any subobject selections that include controllers.
l Skin Details: Displays nodes for the modifiers and controllers that are used when the Skin modi-
fier is applied to a bones system.
You can also limit the number of nodes by using the Include Only options. The Selected Objects option
shows only the objects selected in the viewports. The nodes change as new objects are selected in the view-
ports. The Visible Objects option displays only the nodes for those objects that are not hidden in the view-
ports, and the Animated Objects option displays only the nodes of the objects that are animated.
Object categories that can be hidden include Geometry, Shapes, Lights, Cameras, Helpers, Space Warps,
and Bone Objects. Figure 25.11 shows a single sphere object in the Schematic View window with all the
Include in Calculation options selected.

Without limiting nodes, the Schematic View window can get very busy.

Working with grids and backgrounds
The Schematic View Preferences dialog box includes settings to Show Grid, Snap to Grid, and set Grid
Spacing. The keyboard shortcut for toggling the grid on and off is G. Enabling the Snap to Grid option
makes the nodes snap to the closest grid intersection. This helps keep the nodes aligned and looking neat.
The Background Image section of the Schematic View Preferences dialog box includes a File button that
opens a file dialog box when clicked. Selecting an image file opens and displays the image as a background
image. This is helpful as you arrange nodes. You need to select the Show Image option to see the back-
ground image, and the Lock Zoom/Pan option locks the nodes to the background image so zooming in on a
set of nodes also zooms in on the background image.
