Hi Steve, 

Did you post this on the DXP forum? 

I think they will give you a response over there... in fact they have been
discussing the IPC-D-356 netlist issue... 

 This is a response to a similar question I copied from there by an Altium
rep.

Hi Clifford,
 
The IPC D-356 netlist doesn't get loaded into CAMtastic by itself, you must
generate the Gerbers as well & CAMtastic will load them together with the
IPC netlist. The netlist will be generated regardless of the fact that it'll
not be loaded in CAMtastic alone. If you want to check your board in
CAMtastic the best is to generate the Gerbers, NC Drill & IPC files &
auto-load them in CAMtastic (you can find more info about auto-loading into
CAMtastic in the paragraph "Auto-loading Fabrication Output into the
CAMtastic Editor" in the PDF document mentioned below - TR0127). 
You can find more information about how to output any of the supported CAM
files in the following article "TR0127 Fabrication and Assembly Document
Editor and Object Reference.pdf" (you can find this article in the \Help
sub-directory of your DXP2004 installation). This article contains a lot
more then only CAM files generation so you might have to skip some of the
sections.
 
Hope this helps.

Subject: [PEDA] Gerber format & IPC netlist

Hi folks,

I'm relatively new to Protel after 10 years+ of PADS use. They're different,
and neither is perfect.

One of the good things about PADS is the ability to extract an IPC-D-356
netlist from the PCB file itself. This can be compared with an IPC file
generated from gerbers, and used to check the gerbers match the original
design. It's saved me from scrap boards more than once! To be fair, PADS
requires the running of a Visual Basic script. So, question 1... Is it
possible to generate an IPC netlist from the Protel PcbDoc file (i.e. not
from Camtastic).

Question 2 relates to Gerbers on layers with polygon pours. Any ideas how to
get around the composite layer format? Each gerber file opens as three
layers in ViewMate - one is the copper, one is the cut-outs, one is the text
& lines.

I'm running DXP SP2 build 8.2 on XP Pro SP2.

Cheers,
Steve
