Have you moved the actors? You can always apply the transformation of
the actors to the original datasets before using the append filter.
What other "characteristics" are you talking about? Coloring, etc is
applied very differently to actors than to the actual data. As far as
I'm aware, there is not a way to get a polydata of the entire assembly
directly.
