13 | Basics Windows and Editors Reference > Hypergraph overview Maya gives the nodes the default names shown in the preceding figure. The transform node is nurbsSphere1, the shape node is nurbsSphereShape1. If you rename the transform node, for example, to Bubble, Maya renames the shape node to BubbleShape. If you rename the shape node, Maya does not rename the transform node. Maya doesn't transmit a child's attribute changes up to its parent. Example 2 If you select Create > NURBS Primitives > Sphere to create a sphere, Maya creates a transform node and a sphere node. If you then select Modify > Make Live, then use the Create > CV Curve Tool to draw a curve on the surface of the sphere and turn on the display of shape nodes and underworld nodes, the scene hierarchy appears as follows: Basics 400 Maya gives the nodes the default names shown. The transform node is nurbsSphere1, the shape node is nurbsSphereShape1. The curve1 and curveShape1 nodes are underworld nodes for the curve created on the sphere's surface. When a curve-on-surface is hard to select in the workspace because of crowding or complex geometry, you can select it easily in the scene hierarchy with underworld nodes displayed. Display > Expression Connections/Constraint Connections/Deformer Connections You can display color-coded lines in the scene hierarchy that illustrate nodes connected by an expression, constraint, or deformer. Example Create a NURBS sphere named Ball and a NURBS cone named Cone. Write an expression to assign the value of Ball's translate Y attribute to Cone's translate Y attribute. The expression links the two values. When you move Ball up or down in the view (in a Y-axis direction), Cone moves up or down the same amount. If you select Options > Display > Expression Connections, the scene hierarchy displays this:
