Hey I thought so too, which is kinda why I'm here!

Perhaps my question wasn't clear enough: So far, I've learned that using the startDrag method, users could drag a pre-defined object on a webpage, and using the graphics.lineTo method, users could draw anything they want with a mouse. My question is, what if users want to draw a boat, and drag it across the page, or have it enlarged? Is there a method/function in ActionsScript 3.0 for animating non-pre-defined object? Or how can I make whatever drawings (ball, rocket, dog...) users make into an entity (instead of individual lines) for manipulation?
Thanks for your help!
