I don't really know, but, it seems to me that you can rotate (or work with) those models like that simply because they are "hard programed" into the game in its' base programming, and it is something that we are not allowed to mess with.
I.E. - We can add graphics to the game (in addons, and such) but we are NOT allowed to mess around with the 3D world. That is a "hands off" area.
By-the-way, not having access to the z-axes has been a"thorn in the side" for anyone working on a mapping addon from the beginning.
In my defense, I must say that I have not been able to play the game for two years now and I don't see any way that I'm ever going to again. But, I've [b][i]TRIED[\I][\B] to stay up with the changes to the game. Although it may not have worked that well.
