A sub-object s a subset of an object’s geometry.
Manyobjectshavevarioustypesofsub-objects
that you can work with independently. For
example, an
editable mesh object’s (page 1–984)
sub-objects are vertices, edges, faces, p olygons,
and elements. To access sub-objects, go to the
Modifier panel. In the modifier stack display,
click the pl us-sign button to display an object’s
hierarchy, and then choose the sub-objects level
from the hierarchy. At the sub-objects level you
can select sub-objects, tr ansform the selections,
apply modifiers, and so on.

Sub-Object Level
Edge sub-objects level chosen while editing a mesh.
Some types of objects let you change to a

For example,
editable meshes (page 1–984)
haveVertex,Edge,Face,Polygon,andElement
sub-object levels.
NURBS models (page 1–1079)
canhaveSurface,Curve,Point,SurfaceCV,Curve
CV, and Im port sub-object levels.
You change the active sub-object level using the
Modifier Stack display (page 3–802)
on the Modify
panel.
