I've seen a few examples of drawing programs but they hardly ever have real eraser tools. They either replace something with white, delete entire objects, or don't even have one. I created this one just to show how it's done for those who don't know.

If you want to use shapes for speed, simply create a Sprite object... On MOUSE_DOWN you do your drawing techniques, then on MOUSE_UP, you draw the Sprite to the BitmapData layer and Sprite.clear() your shape.
Easy as pie and allows a real eraser.
