Main Question or Discussion Point

Hi,

I've been plotting potentials and electric fields inside and outside shells; when I create 2 separate RevolutionPlot3D plots for the potentials (1) inside the shell and (2) outside the shell, I'd like to combine them into one plot. I tried using the Show function, but Mathematica doesn't appear to like that route. Any ideas about how to combine the plots?

I've attached the 2 separate Mathematica plots as they exist at the moment.

On a separate note, is there a way to plot using RevolutionPlot3D with a piecewise function? This would bypass the above problem and skip straight to the solution.

Thanks...

I've put the two different functions into a piecewise function, and then revolved a plot from that. The results are great... I just wish I knew why the plot doesn't show at r=1. (See attached)

I figured out that the range of Show defaults to that of the first plot, which would leave out most of the second plot in my case. So I used the option PlotRange->All and that fixed everything up...

This has been a great monologue! Thanks for listening.
