Nope. It makes "child" the parent of "father" (you set the "father"'s parent property
to the "child" model). Switch it around if you want "father" as the parent model:
member("3d").model("Child").parent = member("3d").model("Father")
[ who is the child's parent? model("Father") is... ]

Depends upon what you mean by "change". If you move and/or rotate a parent model, then
any child models move as if they were attached by rods (a child model's position and
orientation relative to it parent stays constant when you move/rotate the parent). For
example, say you have a "car" model with four children (the tires), move the parent
car model and the children go with it. But you can then rotate a child model in place
(simulate steering or driving down the street for example) without affecting the
parent. Similarly you can also translate child models without affecting the parent if
you'd like.
> And can one child have many parents?
No. Each model has one parent specified. But you could have the following
(psuedo-code):
model("great grandparent").parent = group("World")
model("grandparent").parent = model("great grandparent")
model("parent").parent = model("grandparent")
model("child").parent = model("parent")
So the "child" model has a single parent, that has a parent, that has a parent,
etc..., until you reach the top-most possible parent, the World group object. But as I
said, you cannot assign two parents directly to a single model.
