+SetPosition( x, y, z );
- SetPosition( z );
 == Parameters ==
 === Arguments ===
+* x (float) - sets the x-value of the model position
+* y (float) - sets the y-value of the model position
+* z (float) - sets the z-value of the model position
-:; z : float - sets the z-value of the model
+: positive values of x will move the model right, negative will move it left
+: positive values of y will move the model up, negative will move it down
+: positive values of z will bring the model nearer to you, negative will bring it away
+=== Returns ===
+* nil
-: positiv values will bring the model nearer to you, negative will bring it away
+==Notes==
-=== Returns ===
-: unknown, probably nil
+The bottom left corner of the Model frame will always have coordinates (0,0,0).  However, the top right corner's coordinate depends upon the width and height of the Model frame, as well as the screen resolution returned by [[API GetScreenWidth|GetScreenWidth]]/[[API GetScreenHeight|GetScreenHeight]].  The following formula determines the Model-relative coordinate that corresponds to the top-right of the Model frame (''CoordRight'',''CoordTop'',0):
