no you have to use your mouse to do this....there is a tool palette in illustrator and there is a tool called the "pen" tool, the pen tool is your best friend....you have to manually do your lines....
now in photoshop you can use the "magic" wand tool to select your lines....example dragon....this is just a basic sketch...i will show you the selected lines that i do in photoshop (basically what you are talking about)
