The
modifier stack (page 3–802)
is the key to
managing all aspects of object modification. You
use the stack to:
View and manipulate the sequence of modifiers
Find a particular modifier
Adjust a modifier’s p a rameters
S elect a modifier’s gizmo or center
Activate or deactivate a modifier
Delete or disable a modifier
The effect of modifiers is directly related to their
sequence, or order, in the st ack.
Where you put a modifier in the st ack is critical,
because the program applies modifiers in their
stack order, b eginning at the b ottom, and car ries
thecumulativechangeupward.
By clicking any entry in the stack, you go back
to the point where you made that modification.
You can then rework your decisions or d iscard the
modification entirely by deleting it. You can also
insert a new mo difier in the stack at that point.

modifier (page 1–853)
to the end of a cylinder, for
example, the vertices near the end move closer
together. Modifiers make changes in the geometry
that stay in effect until you adjust or delete the
modifier.

Morphing makes the clock appear to melt.
Morphing is a term derived from
metamorphosis,
which means to change physical shape or form.
