Alter shapes with path operations
Path
operations are similar to effects. These live operations act nondestructively on
a shape’s path to create a modified path that other shape operations
(such as fills and strokes) can apply to. The original path is not
modified. Because path operations are live, you can modify or remove
them at any time. Path operations apply to all paths above them
in the same group; as with all shape attributes, you can reorder
path operations by dragging, cutting, copying, and pasting in the Timeline
panel.
- In the Composition panel or Timeline panel, select
the shape group into which to add the path operation.
- Choose a path operation from the Add menu in the Tools
panel or the Timeline panel:
- Merge Paths
- Combines paths into a compound path. (See Merge Paths options.)
- Offset Paths
- Expands or contracts a shape by offsetting the path from
the original path. For a closed path, a positive Amount value expands
the shape; a negative Amount value contracts it. The Line Join property
specifies the appearance of the path where offset path segments
come together. A bevel join is a squared-off connection. A miter
join is a pointed connection. The miter limit determines the conditions
under which a beveled join is used instead of a miter join. If the
miter limit is 4, then when the length of the point reaches
four times the stroke weight, a bevel join is used instead. A miter
limit of 1 causes a bevel join.
- Pucker & Bloat
- Pulls
the vertices of a path outward while curving the segments inward
(Pucker), or pulls the vertices inward while curving the segments
outward (Bloat).
- Repeater
- Creates multiple copies of a shape, applying a specified
transformation to each copy. (See Using the Repeater to replicate shapes.)
- Round Corners
- Rounds corners of paths. Higher Radius values cause greater roundness.
- Trim Paths
- Animate the Start, End, and Offset properties to trim a path
to create results similar to results achieved with the Write-on
effect and the Write On setting for paint strokes. If the Trim Paths
path operation is below multiple paths in a group, then you can
choose to have the paths trimmed simultaneously or treated as a
compound path and trimmed individually.
- Twist
- Rotates
a path more sharply in the center than at the edges. Entering a positive
value twists clockwise; entering a negative value twists counterclockwise.
- Wiggle Paths
- Randomizes (wiggles) a path by converting it into a series
of jagged peaks and valleys of various sizes. The distortion is
auto-animated, meaning that it changes over time without the need
to set any keyframes or add expressions.
Several properties
for this path operation behave the same as properties of the same
name for the Wiggly selector for text animation. (See Wiggly selector properties.) The Correlation property specifies
the amount of similarity between the movement of a vertex and that
of its neighbors; smaller values create more jagged results, as
the position of a vertex depends less on the position of its neighbors.
The Correlation property is similar to Correlation for the Wiggly selector,
except that the Wiggle Paths version specifies the correlation between neighboring
vertices instead of neighboring characters. Set the maximum length
for segment paths using an absolute or relative size. Set the density
of jagged edges (Detail) and choose between soft edges (Smooth)
or sharp edges (Corner).  Animate the Size property
to fade the wiggling up or down. To smoothly accelerate or decelerate
the wiggling, set Wiggles/Second to a constant value of 0, and animate
the Temporal Phase property.
- Wiggle Transform
- Randomizes (wiggles) any combination of the position, anchor
point, scale, and rotation transformations for a path. Indicate
the desired magnitude of the wiggle for each of these transformations
by setting a value in the Transform property group that is contained
in the Wiggle Transform property group. The wiggled transformations
are auto-animated, meaning that they change over time without the
need to set any keyframes or add expressions. The Wiggle Transform
operation is especially useful following a Repeater operation, because
it allows you to randomize the transformations of each repeated
shape.
Several properties for this path operation behave
the same as properties of the same name for the Wiggly selector
for text animation. (See Wiggly selector properties.) The Correlation property specifies
the amount of similarity between the wiggled transformations of
a repeated shape and its neighbor within a set of repeated shapes.
Correlation is only relevant if a Repeater operation precedes the Wiggle
Transform operation. When Correlation is 100%, all repeated items
are transformed in the same way; when Correlation is 0%, all repeated
items are transformed independently.
- Zig Zag
- Converts
a path into a series of jagged peaks and valleys of uniform size. Set
the length between peaks and valleys using an absolute or relative
size. Set the number of ridges per path segment, and choose between
wavy edges (Smooth) or jagged edges (Corner).
