Thanks Jean-Marc,
My first post here - I have discovered the limitations of copying and
pasting. In my notebook, the syntax is correct.
I don't expect an automatic exclusion, but I do get an additional
(unwanted) exclusion at y==0 && x<0 when I use the following command:
Plot3D[ pdfN[{x, y}], {x, -3, 3}, {y, -3, 3}, PlotRange -> Full,
 Mesh -> 30,  ColorFunction -> grayColors, PlotPoints -> 50,
 ClippingStyle -> None,
 Exclusions -> { {ArcTan[x, y] == 0.5,
    x > 0 && y > 0}, {ArcTan[x, y] == -Pi + 0.5, x < 0 && y < 0}},
 ExclusionsStyle -> {None, Directive[Thick, Red]}, MaxRecursion -> 0,
 AxesLabel -> {"x", "y"}]
Regards, Fiona.
