Gizmo—At this sub-object level, you can transform
and animate the gizmo like any other object,
altering the effect of the Skew modifier. Translating
the gizmo translates its center a n e qual distance.
Rotating and scaling the gizmo take place with
respect to its center.
Center—At this sub-object level, you can translate
and animate the center of the Skew effect.
For more information on the stack display, see
Modifier Stack (page 3–802) .
Parameters rollout
Skew group
Amount—Sets the angle to skew from the vertical
plane.
Direction—Sets the direction of the skew relative
to the horizontal plane.
Skew Axis group
X/Y /Z—Specify the axis that will be skewed. Note
that this axis is local to the Skew gizmo and not
related to the sele cted entity. Default=Z.
Limits group
Limit Ef fect —Applies limit constraints to the Skew
modifier.
Upper Limit—Sets the upper limit boundar ies in
world units from the sk ew center point, beyond
which the skew no longer affects the geometry.
Default=0.
Lower Limit—Sets the lower limit boundaries in
world units from the sk ew center point, beyond
which the skew no longer affects the geometry.
Default=0.

The Skin modifier is a skeletal deformation tool
that lets you deform one object with another
object. Mesh, patch, or NURBS objects can be
deformed by bones, splines, and other objects.
Applying the Skin modifier and then assigning
bones gives each bone a capsule-shaped
"envelope." Vertices of the modified objec t within
these envelopes move with the bones. Where
envelopes overlap, vertex motion is a blend
between the envelopes.
