        if (shapes && shapes.length > 0) {
            alert('Retrieved ' + shapes.length + ' from the drawing manager.');
        } else {
            alert('No shapes in the drawing manager.');

Tip: If you want to get a shape right after it was drawn, use the drawingEnded event on the DrawingManager.
