First, do this:
Paste
site:archicad-talk.graphisoft.com "3d rotate"
in your browser's search field.
Check the parameters; if the cladding cannot be rotated, "all" you have to do is to add the rotation parameter. To find how, paste into your search field the following:
site:archicad-talk.graphisoft.com "rotx"
Enjoy
