To reposition a shape or mask as you are drawing, hold the spacebar or the middle mouse button while dragging.
To scale a circle, ellipse, square, rounded square, rectangle, or rounded rectangle around its center while drawing, hold the Ctrl (Windows) or
Command (Mac OS) key after you begin dragging. Don't release the key until you have released the mouse button to finish drawing.
To cancel the drawing operation, press Esc.
Note: Each shape tool retains the settings of the most recent drawing operation with that tool. For example, if you draw a star and modify the
number of points to be 10, then the next star that you draw will also have 10 points. To reset settings for a tool and create a shape with the default
settings, double-click the tool in the Tools panel. (See

3. Release the mouse button to finish drawing. If drawing a square or rounded square, release the Shift key after releasing the mouse button.
Note: Squares are created to be square according to the pixel aspect ratio of the composition. If the pixel aspect ratio of the composition is not 1,
then squares only appear square in the Composition panel if the Toggle Pixel Aspect Ratio button
panel.
Draw ellipses and circles

To draw an ellipse, drag diagonally.
To draw a circle, Shift-drag diagonally.

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
1. 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.
Create a shape or mask the size of the
