3DPlot with axes at the center?

Questions
1

Hi guys , i’m trying to make a 3D plot with the axes at the center, but when i do it i can see through the Plot, does anyone knows how to change it?

Plot3D[{2 (x - y)/(1 + x^2 + y^2)}, {x, -a, a}, {y, -a, a}, 
 AxesOrigin -> {0, 0, 0}, AxesStyle -> Opacity[1], 
 AxesEdge -> {None, Automatic, None}, ColorFunction -> "Rainbow", 
 Boxed -> False, Background -> Black, MeshFunctions -> {#3 &}, 
 Mesh -> 6, MeshStyle -> {Blue}]

Thanks in advance

:smiley:

Is the question about the surface of the plot being able to hide the axis? (I’m not seeing how “axes at the center” has anything to do with the issue.)

yes, if I use the default axes surface of the plot hide the axis, but if I move the axes to the center with AxesOrigin->{0,0,0}I can see through the plot surface
