Would the cross section plot help?

Do you really mean you need to label the intersection (if so, use textplot3d), or do you really mean that you want to plot the intersection (if so, use intersectplot)? For example:

with(plots):
S:= plot3d(x^2-y^2,x=-1..1,y=-1..1, colour=tan, style=patchnogrid):
P1:= plot3d([x,0,z],x=-1..1,z=-1..1.5, transparency=0.8, colour=violet, style=patchnogrid):
P2:= plot3d([0,y,z],y=-1..1,z=-1..1.5, transparency=0.8, colour=violet, style=patchnogrid):
P3:= plot3d([x,y,0],x=-1.2..2,y=-1.2..1.2, transparency=0.8, colour=violet, style=patchnogrid

L1:= intersectplot(surface(x^2-y^2,x=-1..1,y=-1..1),surface(y=0,x=-1..1,y=-1..1,z=-1..1), 
            thickness=2,colour=red):
L2:= intersectplot(surface(x^2-y^2,x=-1..1,y=-1..1),surface(x=0,x=-1..1,y=-1..1,z=-1..1), 
            thickness=2,colour=red):
L3:= intersectplot(surface(x^2-y^2,x=-1..1,y=-1..1),surface(z=0,x=-1..1,y=-1..1,z=-1..1), 
            thickness=2,colour=red):
display([S,P1,P2,P3,L1,L2,L3],  lightmodel=light1, orientation=[60,60], 
                   view=[-1.2..1.2, -1.2 .. 1.2, -1..1.5], scaling=constrained);

WOW! Stunned...

Again, WOW!

Dude?! You should be paid for this...
