Draw and erase in AS3 help needed

Question

Hello all
I have a 200x200 movie clip in a certain position I am trying
to draw in as3, and then erase it to reveal another clip
underneath. I am not able to specify the erase brush to be active
just on top of that clip not on all over the stage.
Here what I have so far , scratch is the name of my original
clip I am drawing back
var bitmap:Bitmap=new Bitmap();
var bd:BitmapData=new
BitmapData(scratch.width,scratch.height,true,0x00FFFFFF);
bd.draw(scratch);
bitmap.bitmapData=bd;
addChild(bitmap);
bitmap.x = 200;
bitmap.y = 200;
removeChild(scratch);
but when I start erasing I have to start from 0,0 to erase my
bitmap.
THanks for your help

And how would i go about doing that?By making a proper design.
This way, I can easily do what the object itself is made to do, without writing alot of code that checks what kind of object was sendt.
The first way I did this was:
Psudo Code:
Object obj = input.readObject();
String type = obj.getClass().toString();
if (type.contains("logonObject")) {
} else if (type.contains("playerObject")) {
I don't think that's relevant. I don't see where that code uses anything which is specific to the server and to the client. Those class names look like they belong in the server, so that code shouldn't be in a "shared" class. It should be in a "server" class.
As for the issue of having to tell what kind of object was sent, I'm sure there are better ways than just sending an object and then having the receiver inspect the object to see what kind of object it was.
