5 | Nodes and attributes How do I? > Node types 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: 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.
