Say you don't like where the water spawned. Instead of having to move your crosshair over 20 meters to get it exactly where you want it you can add a position.
The base format is.
#spawndis water1 Water X Y Z
Where X is the East-West movement, Y is the North-South, and Z is the Height.
After you spawn the water somewhere (using your LOS, or crosshairs) the ChatBox will tell you something like
"Spawned Water1 at 2056.7 189.65 35.1"
Manipulate those numbers to get it where you want it; 1 = 1 meter. After playing around with it for awhile, you should get the hang of it.
As for Rotations, it goes..
#spawndis water1 Water X Y Z r1 r2 r3
This r 's are diffrent axis's (axi?) that you can rotate the dis from.
I think that 1.57 equals a 180 degree rotation. So if you wanted to turn a chair around it would be...
#spawndis chair Chair 2531 189 50 0 0 1.57
(Change the XYZ accoridngly.)
Leave the rotations you don't want to change 0, You'll just have to play with it a bit to really understand it. [Post if you need more help]
