Hi,
I have tried another run on files that were not successfully converted.
For sample this file:
mac:brl-cad-conv lothar$ ls -l gta02-mme01_asm.igs*
-r--r--r-- 1 lothar staff 152091796 30 Jun 16:09 gta02-
mme01_asm.igs # Converts to
-rw-r--r-- 1 lothar staff 104 24 Sep 18:55 gta02-
mme01_asm.igs.g # this, when deleted
mac:brl-cad-conv lothar$ ./convert.sh
#!/bin/sh
for file in *.igs; do
if [ ! -e $file.g ]; then
/usr/brlcad/bin/iges-g -t -o $file.g $file
fi
done
Can anybody else convert this file ?
Thanks
Lothar
