For those of us who find the quirks of drawing with vectors frustrating, the Live Paint function is a great option. Live Paint allows you to fill and color things the way you see them on the screen, even if the vector spaces have not been defined as such. Because Live Paint is different from other fill options, it can be confusing when you decide you want to join two objects that have been Live Painted together. Merging the items is different, but certainly not difficult.
