Drawing masks and shapes using b-splines – Apple Motion 4 User Manual

Tip: If you need a closer look at what you’re doing, magnify the Canvas while drawing a
shape. Use Command-Equal Sign (=) to zoom in and Command-Hyphen (-) to zoom out.
You can scroll around by pressing the Space bar as you drag in the Canvas. If you have
a Multi-Touch trackpad, it’s even easier: pinch open or closed to zoom in or out, and use
a two-finger swipe to scroll around.

To finish the shape, do one of the following:
• Click the first point you drew to create a closed shape.
• Press C to close the shape, joining the first point you created to the last.
• Double-click anywhere in the Canvas to create the last point of an open shape.
• Press Return to create the last point of an open shape.
Note: Before a shape is closed, you can press Esc at any time to cancel the entire operation,
deleting the shape.
Immediately after finishing a shape, the Shape HUD appears and the Adjust Control Points
tool is selected, which allows you to edit the shape you’ve just created.
Note: Once you have finished drawing a shape, press Esc to change to Select/Transform
mode.
