Box2d dynamic size

vvvv beta question

Hi
is there a way to change the size of an element in a box2d environment after the item has been created. I see I can change the position with UpdateBody, but how to change the size?

Thanks!

I am right then assuming that a Body will always create a Shape by default? (trying to understand the difference between shape and body)
