Plotting Quadric Surfaces

[Dr Howard Solomons]

I want to plot the intersection of two rules surfaces, a hyperboloid and a hyperbolic paraboloid. I have the equations of each in terms of x^2, y^2, z^2,x*y, x*z, y*z. Can I plot this with DPlot? If so, how?
Thanks folks

I assume you mean you want to plot two surfaces such that you can see the intersection, rather than plotting only the intersection. If so, no - sorry, DPlot currently allows only one surface per plot. Multiple surfaces is on my to-do list but I cannot promise a release date.
