You can scale and rotate an entire mask or
shape path (or selected vertices in one or more paths) using the
Free Transform Points command. When you use this command, a free-transform
bounding box surrounds the selected vertices, and an anchor
point appears in the center of the bounding box to mark the anchor
point for the current transformation. You can scale and rotate the
selected vertices by dragging the bounding box or its handles. You
can also change the reference point from which the vertices are
rotated or scaled by moving the bounding box anchor point. The free-transform
bounding box handles and anchor point exist independently of the
handles and anchor point for the layer.
Note: When you animate
rotation using Free Transform Points, the vertices of the mask are
interpolated in a straight line from keyframe to keyframe. For this
reason, the results may be different from what you expect.
- Display the layer containing the paths that you
want to transform in the Composition or Layer panel.
- Using the Selection tool, do one of the following:
To transform any number of vertices, select
the vertices that you want to transform and choose Layer > Mask
And Shape Path > Free Transform Points.
To transform an entire mask or shape path, select
it in the Timeline panel and choose Layer > Mask And Shape Path
> Free Transform Points.
- To move the anchor point of the bounding box, place the
Selection tool over the bounding box anchor point
 until
the Selection tool changes to a move anchor point icon  . Drag
to position the anchor point.
- Do any combination of the following:
To move the path or selected vertices,
position the pointer inside the bounding box and drag.
To scale the path or selected vertices, position
the pointer on a bounding box handle and, when the pointer changes
to a straight, double-sided arrow  , drag
to a new size. Hold down Shift as you drag to constrain the scale.
Hold down Ctrl (Windows) or Command (Mac OS) as you drag to scale
around the anchor point of the bounding box.
To rotate the path or selected vertices, position
the pointer just outside the free-transform bounding box and, when
the pointer changes to a curved double-sided arrow  , drag
to rotate.
- To exit free-transform mode, press Esc, Enter (Windows),
or Return (Mac OS).
