Create a Bezier shape or mask using the Pen tool
You can create a Bezier mask using
the Pen tool on a selected layer in the Composition panel or Layer
panel. You can create a shape with a Bezier path using the Pen tool
on a selected shape layer in the Composition panel. If you draw
with the Pen tool in the Composition panel with no layer selected,
you create a shape on a new shape layer.
Creating a RotoBezier
path is similar to creating a manual Bezier path. The primary difference
is that direction lines for vertices and curvature for path segments
are automatically calculated.
Create a manual Bezier path using the Pen tool- With the Pen tool selected and the RotoBezier
option deselected in the Tools panel, click in the Composition panel
where you want to place the first vertex.
- Click where you want to place the next vertex. To create
a curved segment, drag the direction line handle to create the curve
that you want.
 To reposition a vertex after you’ve
clicked to place it but before you’ve released the mouse button,
hold the spacebar while dragging. The last vertex that
you add appears as a solid square, indicating that it is selected.
Previously added vertices become hollow, and deselected, as you
add more vertices.
- Repeat step 2 until you are ready to complete the path.
- Complete the path by doing one of the following:
To close the path, place the pointer over
the first vertex and, when a closed circle icon appears next to
the pointer  , click
the vertex.
Note: You can also close a path by double-clicking
the last vertex or choosing Layer > Mask And Shape Path >
Closed.
To leave the path open, activate a different tool,
or press F2 to deselect the path.
Draw straight manual Bezier path segments with the Pen toolThe simplest path that you can draw with the
Pen tool is a straight line, made by clicking with the Pen tool
to create two vertices. By continuing to click, you create a path
made of straight line segments connected by corner points.  Clicking with Pen tool creates straight segments. - Place the Pen tool where you want the straight
segment to begin, and click to place a vertex. (Do not drag.)
- Click again where you want the segment to end. (Shift-click
to constrain the angle between segments at the corner point to a
whole multiple of 45°.)
- Continue clicking to set vertices for additional straight
segments.
Draw curved manual Bezier path segments with the Pen toolYou create a curved path segment by dragging
direction lines. The length and direction of the direction lines
determine the shape of the curve.
Shift-drag
to constrain the angle of the direction lines to whole multiples
of 45°. Alt-drag (Windows) or Option-drag (Mac OS) to modify only
the outgoing direction line. - Place the Pen tool where you want the curve to
begin, and hold the mouse button down.
A vertex appears, and the Pen tool pointer changes to an
arrowhead.
- Drag to modify the length and direction of both direction
lines for a vertex, and then release the mouse button.
 Drawing the first vertex in a curved path - A.
- Placing the Pen tool
- B.
- Starting
to drag (mouse button pressed)
- C.
- Dragging
to extend direction lines
- Place the Pen tool where you want the curved segment
to end, and do one of the following:
To create a C-shaped curve, drag in the
direction opposite from the direction that you dragged the previous
direction line, and then release the mouse button.
 Drawing the second vertex in a curved path - A.
- Starting to drag
- B.
- Dragging
away from previous direction line, creating a C curve
- C.
- Result
after releasing mouse button
To create an S-shaped curve, drag in the same direction
as the previous direction line, and then release the mouse button.
 Drawing an S curve - A.
- Starting to drag
- B.
- Dragging
in same direction as previous direction line, creating an S curve
- C.
- Result
after releasing mouse button
- Continue dragging the Pen tool from different locations
to create a series of smooth curves.
