The Skew modifier lets you produce a uniform
offset in an object’s geometry. You can control the
amount and direction of the skew on any of three
axes.Youcanalsolimittheskewtoasectionof

Procedures
To skew an object:
1.
Select an object, go to the Modify panel,
and choose Skew from mo difier list.
2. On the Parameters rollout, set the axis of the
skew to X, Y, or Z. This is the axis of the Skew
gizmo, not the axis of the selected object.
You can change the axis at any time, but only
one a xis setting is carr ied with the modifier.
3. Set the amount of the skew. The amount is an
offset i n current units parallel with the a xi s.
The object skews to this amount beginning at
the lower limit, by default the location of the
modifier’s center.
4. S et the direction of the skew.

You c an reverse the amount and direction by
changing a positive value to a negative value.
To limit the sk ew:
1.
Turn on Limits group > Limit Effect.
2. Set values for the upper and lower limits. These
are distances in current units above and below
the modifier’s center, which is at zero on the
gizmo’s Z axis. The upper limit can be zero or
positive, the lower limit zero or negative. If the
limits are equal, the result is the same as turning
off Limit Effect.
The skew offset is applied b etween these limits.
The surrounding geometr y, w hile unaffected
by the skew itself, is moved to keep the object
intact.
3. At the sub-object level, you can select and move
the modifier’s center.
The limit settings remain on either side of the
center as you move it. This lets you relocate the
skew area to another part of the object.
