Michael Trott notes a problem with ParametricPlot3D. Here is another. The
4th argument to ParametricPlot3D can not be a list of graphics directives.
For example
ParametricPlot3D[{t,t,t,{RGBColor[1,0,0],Thickness[.02]}},
{t,0,1}]
does not apply either graphics directive to the plot. A look at the input
form tells why. The graphics directives are passed as a list to Graphics3D.
The fix is simple. Simply map Flatten across the output of ParametricPlot3D.
Show[Map[{Flatten[#,3]}&,
ParametricPlot3D[{t,t,t,{RGBColor[1,0,0],Thickness[.02]}},
{t,0,1},DisplayFunction->Identity]],
DisplayFunction->$DisplayFunction]
I have reported this problem to WRI. I hope they fix it soon.
