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 modifier on an object
The modifiers you apply to an object are stored
in a stack (page 3–973). 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 stack and m ake your
changes permanent.
There are other general things to know about using
modifiers:
• You can apply an unlimited number of
modifierstoanobjectorpartofanobject.
• Whenyoudeleteamodifier,allitschangesto
the object disappear.
• You can move and copy modifiers to other
objects using controls in the modifier stack
display (page 3–760).
• The order or sequence in which you add
modifiersisimportant.Eachmodifieraffects
thosethatcomeafterit.Forinstance,addinga
Bend modifier (page 1–560) before a Taper (page
1–863) can give you distinctly different results
than if you first added the Taper followed by
the Bend.

Modifiers and transforms differ in how they affect
an object and the order in which they are applied
to an object.
Transforms

manipulations. Unlike most modifiers, t r ansforms
are independent of an object’s internal structure,
and they always ac t in world space (page 3–1036).
An object can carry any number of m odifiers, but
it always has only a single set of t ransforms.
