I purchased a room with funiture and items.  The room and all items loads as props.  I want to use the room turned 90 degrees from what it loads by default. Is there a way to group all of these props for rotation?  I normally go into all 30 or 40 items and assign a new parent like floor. and then rotate it. This just seems like the hard way.  Is there a trick to getting all the objects to to rotate as one object or group?  

I could load a null object, assign all the lights to it and just rotate the custom light set, but I want the references aligned with the view (z axis).

thanks for any help,
