Using Shape Hints
Most of the time, certain problems arise when you create the shape tween. Shape tweening may go not the way you want it to. For example, tweening the triangle into a square will not look effective. To avoid this you can use the shape hints. Shape hints mark the respective points of initial and final figure during the shape tweening. Usually shape hints are placed at the angles of the figures and its sides.
It is better to start placing the shape hints counter-clockwise from the top left corner of the figure. Shape hints are automatically named in alphabetical order from A to Z, so that one shape tween cannot contain more than 26 shape hint points.
The shape hints at initial figure are yellow while shape hints at the final figure are green. Until the shape hints are not placed on the image, they are red.
To add the shape hint to the animation, select the first frame and press Ctrl+Shift+H hotkey or go to Modify > Shape > Add Shape Hint. Shape hints will appear at the keyframes and you will need to place them as you want with the mouse. To remove the shape hint it is enough to drag it away from the workspace (other shape hints will automatically be renamed). All shape hints are removed by pressing Modify > Shape > Remove All Hints hotkey. Shape tweening will look much better with the shape hints.
