Don,
Thanks for the help. I run L3P like this:
set PATH=C:\LDRAW;
set LDRAWDIR=C:\LDRAW
l3p.exe -stdout -ca1.000000 -cg30.000000,45.000000,60000.000000 -q2 -b0x02ffffff
-o LDraw\CAR.DAT POV\CAR.pov
and I get this result rendering at 800x600

I run ldglite like this:
set PATH=C:\LDRAW\ldgliteexe1_0_7;
set LDRAWDIR=C:\LDRAW
ldglite.exe -l3 -mS -i2 -z-100000 -Z100000 -j -ca1 -cg0,0,60000.000000 -v800,600
-fh -w1 -q C:\LDRAW\MODELS\LDraw\CAR_l.dat
and I get this result:

I'm using a lense angle of 1 to approximate orthographic.
