Example: Stack display of mes h showing its sub-objec t
hierarchy, and Edge sub-object level chosen
The modifier stack (page 3–760) 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 stack.
Where you put a modifier in the stack is critical,
because t he program applies modifiers in their
stack order, beg inning at the bottom, 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 discard the
modification entirely by deleting it. You can also
insert a new modifier in the stack at that point.
Modifiers
Example: effects of the twist modifier on an object
Modifiers (page 1–499),asthenameimplies,
modify an object’s geometrical structure,
deforming it in some way. When you apply a taper
modifier (page 1–863) to the end of a cylinder , for
example, the vert ices near the end move closer
together. Modifiers make changes in the geometry
that stay in effect until you adjust or delete the
modifier.
