Well that’s good to know.  I had no idea that there was a difference other than 
appearance which I just attributed to the font.  He did get it running 
yesterday using the same command, but we had no idea why. Thanks for the help.  
Any news on an update for BRL-CAD? It’s been a while.

Hi Sean,
A co-worker, John Davis (CC’d above), is having an rtg3 issue when attempting 
to run on Windows.  I remembered working with you in the past to correct the 
same problem where it was trying, and failing, to locate a ray_data_file.  The 
fix back then was to use the –c “set ray_data_file=temp.txt” argument on the 
rtg3 command line where temp.txt was just a blank text file co-located with the 
target model.  Before I told John to do this, I attempted it here, and it ran 
fine.  He then made an attempt and got an rt_do_cad(oset): Command not found 
error as shown in the screen grab below.  Can you help him out on this while 
keeping me in the loop for my own knowledge?

Hi Bob, absolutely!  Your memory is better than mine on this particular issue.  
I'm surprised a fix was not put in place... nor was it even recorded, but I've 
added a note now for someone to look into it.


1.       In the directory you are running the shotlines, add a blank text file 
called “temp.txt”.

2.       On the command line before you specify the target name, add the 
following argument…

-c “set ray_data_file=temp.txt”

The problem is that John apparently copy-pasted this directly from your e-mail, 
which is rich-encoded, instead of typing it in.  Your e-mail client helpfully 
turned your double-quotes into "smart quotes" which do not work in cmd.exe nor 
with rtg3.  Basically, “ vs " -- they're different characters.

If he types in his double-quotes, should work.  This should also be plain text 
copy-pasteable:
-c "set ray_data_file=temp.txt"

Cheers!
Sean
