Well, I wouldn't use the SURFACE command, for starters. :-)
SURFACE is not really a 3D routine. It's more of a 2.5D
routine. The Z-axis must *always* be vertical in any rotation
of the SURFACE command. This is probably why your lines
are distorted in the views you are choosing.
I'd do this in object graphics, which is really 3D. Then
you could get a nice flat plane to display your surface on.
Cheers,
David
