Steve,
You asked if ODB++ was dead. I would ask was it every really alive?
I have written a lot of EDA to machine code and I have looked at ODB++,
CADCAM, Offspring, .... and I have some thoughts.
All these high level CADCAM files are really designed as data exchange
formats. In addition to the raw image data then include layer, BOM,
supplier, tons of stuff. It has been my experience that very few engineering
departments have the degree data organization required to populate a ODB++
file beyond the image info. Using ODB++ or other advanced formats in this
manner offers little over RS-274X. Including a net list for board test is
about all I can think of that would be a serious help.
I wrote a reader for RS-274D and X and I have processed a good number of
these files. The quality of most RS-274 generators (PCB CAD Tools) is not
encouraging. Suppliers seem to provide quick and dirty RS-274 output and I
can not see them supporting high level outputs. As proof I suggest you ask
PCB CAD Tool User is their tool produces "Perfect Gerbers" all the time.
The other issue is protecting design information. Since gerber files are
void of higher level design data sending your files in gerber format protect
company IP.
Thanks,
Bob Kondner

Stephen,
I normally work with the Gerber files but my occasionally I get a screen
shot with a question from Photo Stencil and it has Trilogy 5000 screen
capture. So I think it is safe to say Photo Stencil can handle ODB++ files.
You should be able to output from Valor to Gerber 274X format as well.
Good Luck,

Subject: [TN] Making a stencil from OBD++ Files
Hi All,
Do any of you know of any stencil vendors that can make stencils from a
OBD++ file?
I had one vendor in the past, but it was a few day affair,they had to do a
lot of extra work to get something they could use to make the stencil. I
thought ODB++ files were supposed to be the next big thing for manufacturing
data.
I had to download a Valor viewer to look at it, but once I did that there
was so much good information about the board in there. All the layer data,
the BOM, footprints for components, fab drawing, ect.
I sent it to our current stencil vendor and they said that it was just a
text file and they couldn't use it
Is OBD++ dead?
Steve
