Using M odifiers
Modifiers provide a way for you to sculpt and
edit objects. They can change the geometry of an
object, and its properties.
Example: effects of the Twist m odifier on an object
The modifiers you apply to an object are stored
in a
stack (page 3–1067) . By navigating up and
down the stack, you can change the effect of the
modifier, or remove it from the object. Or you
can choose to “collapse” the st ack and ma ke your
changes permanent.
There are other general things to know about using
modifiers:
• You can apply an unlimited number of
modifierstoanobjectorpartofanobject.
• When you delete a modifier, all its changes to
the object disappear.
• You can move and copy modifiers to other
objects using controls in the
modifier stack
display (page 3–802)
.
• The order or sequence in which you add
modifiersisimportant.Eachmodifieraffects
thosethatcomeafterit. Forinstance,adding
a
Bend modifier (page 1–541) before a Tap e r
(page 1–853)
can give you distinctly different
results than if you first added the Taper followed
by the Bend.

How M odif ier s Dif fer f rom Tra nsfor ms
Modifiers and transforms differ in how they affect
an object and the order in w hich they are applied
to an object.

manipulations. Un like most mo difiers, transforms
are independent of an object’s internal s tructure,
and they always ac t in
