Implicit plots

HI

I have two implicit functions given by F1(x,y,z) and F2(x,y,z) and I want to plot (in R^3) the curve that satisfy both F1(x,y,z) = 0 and F2(x,y,z) = 0 (if exists). Someone can help me please?

Thank you
Tiago

This is a different problem from the first post in
this thread. Use isosurface for this.
