I am not able to show a point in a three 3 Parametric3D Graphic . Here is my code
Show[
ParametricPlot3D[{{Sin[x], x, y}, None, None,
None}, {x, -\[Pi], \[Pi]}, {y, 0, 3}],
ParametricPlot3D[{None, {Sin[x - 3], 1 - x, y}, None, None}, {x, 0,
3 \[Pi]}, {y, 0, 3}],
ParametricPlot3D[{None,
Point[{2, 2, 1}], {Abs[x - 1], 1 - y^2, y*Pi}, None}, {x, 0,
3 \[Pi]}, {y, -4, 3}],
ParametricPlot3D[{None, None, None, {x - 3, 1 y, Pi}}, {x, 0,
3 Pi}, {y, -4, 3}],
ImageSize -> Medium]
