Two questions



I have two questions that I hope someone can help me with.

1) Is there a way to use Plot3D to create a ``wireframe" surface
plot---that is, showing only the grid curves? (No, Shading->False is
not what I'm after. I want the plot to be _transparent._) If not, is
there a better way to do it than plotting curves with ParametricPlot3D?

2) I am continually forgetting to load a package before entering a
command that it contains. Is there a way to get out of the resulting
jam without quitting the kernel?

Thanks!
