But I'm having trouble plotting a vertical pl= ane in Plot3D. I've got a surface graph, but I want to overlay an transpa= rent plane at a set value on the x axis. So, I want to plot x=80 for al= l y and z. Plot3D[x = 80, {x, 0, 100}, {y, 0, 100}] just gives me z=80 for all x and y (i.e. a horizontal plane) Cheers,Greg =
