Shear objects
Shearing
an object slants, or skews, the object along the horizontal or vertical axis,
or a specified angle that’s relative to a specified axis. Objects
shear relative to a reference point which varies depending on the
shearing method you choose and can be changed for most shearing
methods. You can lock one dimension of an object as you shear it,
and you can shear one object or multiple objects simultaneously.
 Shearing
is useful for creating cast shadows.  Shearing relative to the center (left) compared to shearing
relative to a user-defined reference point (right)
Shear objects with the Shear tool- Select one or more objects.
- Select
the Shear tool
.
- Do
one of the following:
To
shear relative to the object’s center, drag anywhere in the document window.
To
shear relative to a different reference point , click
anywhere in the document window to move the reference point, move
the pointer away from the reference point, and then drag until the
object is at the desired slant.
To
shear along the object’s vertical axis, drag anywhere in the document window
in an up or down direction. To constrain the object to its original width,
hold down Shift.
To
shear along the object’s horizontal axis, drag anywhere in the document window
in a left or right direction. To constrain the object to its original
height, hold down Shift.
Shear objects with the Shear command- Select
one or more objects.
- Do
one of the following:
To
shear from the center, choose Object > Transform >
Shear or double-click the Shear tool .
To
shear from a different reference point, select the Shear tool and
Alt‑click (Windows) or Option‑click (Mac OS) where you
want the reference point to be in the document window.
- In
the Shear dialog box, enter a shear angle from ‑359 to 359. The
shear angle is the amount of slant applied to the object in a clockwise
direction and is relative to a line that’s perpendicular to the
shear axis.
- Select
the axis along which to shear the object.
If you
chose an angled axis, enter a value between –359 and 359, relative
to the horizontal axis.
- If
the objects contain a pattern fill, select Patterns to move the
pattern. Deselect Objects if you want to move the pattern but not
the objects.
- Click OK,
or click Copy to shear a copy of the objects.
Shear objects with the Free Transform tool- Select one
or more objects.
- Select
the Free Transform tool
.
- Do
one of the following:
To
shear along the object’s vertical axis, start dragging the middle-left
or middle-right bounding-box handle, and then hold down Ctrl+Alt
(Windows) or Option+Command (Mac OS) as you drag up or
down. You can also hold down Shift to constrain the object to its
original width.
To
shear along the object’s horizontal axis, start dragging the top-middle
or bottom-middle bounding-box handle and then hold down Ctrl+Alt (Windows)
or Option+Command (Mac OS) as you drag right or left. You
can also hold down Shift to constrain the object to its original
height.
Shear objects with the Transform panel- Select one or more objects.
- In
the Transform panel, enter a value in the Shear text box.
To change
the reference point, click a white square on the reference point locator before
you enter the value.
 You can also call up the
Transform panel by clicking X, Y, W, or H in the Control panel.
