Hi,

create the plot, convert it to a Graphics3D[] and
apply the transformation, i.e.

Graphics3D[
  Plot3D[Sin[x*y], {x, 0, Pi}, {y, 0, Pi}, 
DisplayFunction -> Identity]] /.
    Polygon[pnts_] :> Polygon[{1, -1, 1}*# & /@ 
pnts] //
Show[#, DisplayFunction -> $DisplayFunction] &

Regards

  Jens

| Thank you, but it's not what I'm looking for, 
that's just determining
| where the axes should be drawn.
| Perhaps I explained it badly:
| I want to draw
| Plot3D[Sin[x y],{x,-Pi,Pi},{y,-Pi,Pi}] but in a 
way that it looks like
| I draw
| Plot3D[Sin[-x y]],{x,-Pi,Pi},{y,-Pi,Pi}]], so 
that the positive x-axis
| and the negative x-axis are switched, it should 
start with "+Pi" (left
| side in default ViewPoint) and end with "-Pi" 
(right side in default
| ViewPoint), but it should still show "Sin[x y]". 
Just one axis is
| rotated for 180 degree.
| Of course it's not Sin[x y] that I want to plot, 
that is just an
| example. I have a 3D-plot where the most 
important things can be seen
| in one corner that you don't get to see in the 
front simply by changing
| the ViewPoint, you somehow have to invert one 
axis of the plot.
|
| Thank you.
