Hey indygo-
I'm not a techie- sorry. When you're in game you might a) ask in gossip channel and you may get an instant response from someone who knows and /or/ and do the /who GM command and ask a GM if any are on, or send a petition to a GM while you're ig.
I don't know if the pswiki has such info on commands... but that's another idea
Finally I think it's something like /00, 00, 00 which represents degrees of axis of placement. Target the item, and do (something like this!) /00, 90, 00 to get a 90 degree orientation.... in lieu of someone answering who actually knows this, maybe at least you could play around with that and see if it works...
Good luck!
RR
