Shade_surf : HELP [message #1681]

I am currently using PV-WAVE CL v3.1. And I have a 2-D array of 181 by
81(intervals between grid pts are 10m), with the values in this array
ranging from -1m to about 7m.
When I use shade_surf to view the surface, the routine transforms the
data coordinates to normalized coordinates and display it(the 900m x 400m
x 8m vol is squeezed into a 1x1x1 cube), which makes the display out of
propotion.
I have tried to set !x.s, !y.s and !z.s but seems that every time
I call shade_surf, the routine reset these 3 values, I have also tried
using 3td, but shade_surf will only work with 3td only if the transformed
data is placed with the z-axis vertically on the screen.(I need a 3d output)
Can anybody help me??
