Overview
5-2: Creating and Updating BOMs
Overview
BOM Generating Programs
The three basic Engineering programs that create BOMs are:
•
bn_bomprocess
—Used for schematics produced by Viewlogic and run from
a UNIX command line, or from within Viewlogic’s Workview panel, to create
Material Group 920 BOMs. (See
BOM Structures
on page E-9.)
•
mechbom
—Used to create BOMs not associated with the 920 material
group; runs
bn_bomprocess
internally.
•
xcelbom
—Used by acquisitions for all BOMs when
bn_bomprocess
and
mechbom
are not options; runs
bn_bomprocess
internally.
Configuration Files
These programs use a configuration file, typically
part
.
cfg
(for details, see
The
Configuration File
on page 5-16), which specifies a great deal of information,
including:
• Which files to include during the process.
•If
bn_bomprocess
is to run the Viewlogic Part Lister tool to generate a new
parts list based on the schematic.
If you run
bn_bomprocess
and specify a config file on the command line
(
bn_bomprocess
ProjectName
), it will create one for you if it does not already
exist in your current directory.
Input and Output directories
Creating or processing a BOM essentially involves:
• Putting files into a pre-release area such as:
• A directory specified by the
bn_bomprocess
configuration file (see
The
Configuration File
on page 5-16)
• Your working directory
•/bay
dir
/dra/common/
assembly
• A subdirectory within
/bay
dir
/dra/2brel
