Hi
What is happening is that you are trying to assign the faces of the box to
two different parents- the Box and the BranchGroup (or TG) that you assign
the Shape3Ds to.
Your call to Box.getShape(i) returns a reference to the same face used in
the Box, not a seperate object. When you try to assign the shape3ds to
another group, it throws a multiple parent exception.
Try creating a new Shape3D with the reference that is returned in
getShape(i).
Shape3D boxshape = Box.getShape(i)
Shape3D shape = new Shape3D(boxshape.getGeometry())
B.D.
