You can create additional shapes by clicking the Add Shapes button.
1.
Click the Add Shapes button.
This will put you automatically into Add Shapes mode, and you can add another shape.
2.
Draw another shape and close it by clicking the first knot.
You can modify the shape by adjusting the transform control in the center of the shape. The small knobs going up and to the left are the Y and X scale parameters, respectively. The diagonal knot will scale both X and Y. The longer knob to the right will rotate it. Grabbing in the middle and dragging will move the shape.
3.
Experiment with the various shape transform controls.
Tip
To move the transform control without modifying the shape, press Control and drag with the left mouse button.
