You can use the Draw tool to create your own shapes.
The pointer changes from an arrow to a small pen tip.
Each point you add is connected to the preceding point.
To stop drawing and leave the shape open (no line between last and first points) double click the last point created.
To change the shape's contours, you must first make the shape editable; see Editing Shapes.
To learn about manipulating and aligning shapes, and changing their general object properties, such as color, border style (stroke), size, orientation, shadows, and more, see About Manipulating, Arranging, and Changing the Look of Elements.
