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.
