Upgrading from:

Graphics`ParametricPlot3D`

RevolutionPlot3D and SphericalPlot3D have been added to the built-in Mathematica kernel.
RevolutionPlot3D includes the functionality of CylindricalPlot3D.

RevolutionPlot3D plots in cylindrical coordinates:

Version 5.2 << Graphics`ParametricPlot3D`; CylindricalPlot3D[(1 + Sin[phi]) r^2, {r, 0, 1}, {phi, 0, 2 \[Pi]}]

SphericalPlot3D has been added to the built-in Mathematica kernel:

Version 5.2 SphericalPlot3D[2, {theta, 0, \[Pi]}, {phi, 0, 2 \[Pi]}]

PointParametricPlot3D was available in previous versions of Mathematica and is now available on the web at library.wolfram.com/infocenter/MathSource/6767.
