The error occurs with this code from the your file:
#if (QUAL > 0)
#declare _4319_dot_dat_slope = object {
// Hinge Bar 8 with Split Rod Holder
lg_4319_slope
matrix <0,0,-20/LG_BRICK_WIDTH, -20/LG_BRICK_WIDTH,0,0,
0,-24/LG_BRICK_HEIGHT,0, 0,0,0>
}
#end
You can find that code beginning on line 11486 of the POV file. If you look in
the LGEO library and open file lg_4319.inc (open in WordPad) you will notice
that there is NO definition of [lg_4319_slope] ONLY [lg_4319] and
[lg_4319_clear]. So when you attempt to run the file POV CAN NOT find the
definition of [lg_4319_slope]. If you just rename [lg_4319_slope] to [lg_4319]
your file will be okay.
I am not too familiar with ALL the code in LGEO or how it works. The original
author has not updated his code in a long long time (2 years) and I don't know
all of his logic but this happens every now and then when you use the LGEO
library.
Hope this helped,
