Click the disclosure triangle next to the Rotation parameter to reveal additional
subparameters:

• Animate: This pop-up menu allows you to set the interpolation for animated 3D rotation

channels to one of two options:

• Use Rotation: The default interpolation method. Pattern elements rotate from their

start rotation to their final rotation. Depending on the animation, the elements may
twist this way and that before reaching their final orientation (the last keyframed
value). For example, if the X, Y, and Z Angle parameters are animated from 0 degrees
to 180 degrees in a project, the elements rotate on all axes before reaching their final
orientation.

• Use Orientation: This alternate interpolation method provides for smoother

interpolation but does not allow multiple revolutions. It interpolates between the
pattern elements’ start orientation (first keyframe) to their end orientation (second
keyframe).

Note: The Rotation parameter must be keyframed for the Animate parameter options
to have any effect.

Scale:

Controls the percentage representing the object’s scale, relative to its original size.

By default, the horizontal and vertical scale of an object is locked together at the object’s
original aspect ratio—all of which is represented by a single percentage. Click the
disclosure triangle to display independent percentages for the X, Y, and Z scales of the
object.

Note: Setting an object’s scale to a negative value flips the object.

Shear:

Defines the X and Y shear of the object. An object with no shear has X and Y shear

values of 0. Positive values shear in one direction, while negative values shear in the other.

Anchor Point:

Defines the X, Y, and Z position of the anchor point relative to the center

of the object. Coordinates of 0, 0, 0 center the anchor point in the bounding box defining
the outer edge of the object.

Blending Parameters

Opacity:

Defines the transparency of the object. For more information, see
