Include Files
INCLUDE_FILE /

How many include files you have, where they are, and what you name them are
your option, subject to any other guidelines.
On the East Coast, the file is typically named
Project
.
lst
or
PCB_Assy_Number
.
lst
. It contain lists of mechanical parts that do not appear in a
schematic. This file is usually maintained by a mechanical engineer, who puts it
by default in
/bay
dir
/dra/2brel/mech/pwahdw
.
On the West Coast, the
pwahdw
directory isn’t used, and the filenames are
different.
Each part is listed on one line in the following format, where only the part number
and quantity are required:
part_number
[
| description
]
| quantity
[
| item number
] [
| ref des list
]
If you use item numbers starting at 900, they will appear at the bottom of the
BOM since the items in the BOM are listed from lowest to highest number. This
makes them easy for people to find. (The revision register should be Item 0,
however.)
The following lines are from a typical include file. Notice that (a) 300979-A must
be a revision register because its item number is 0; and (b) the other items are
numbered beginning at 900:
# Part no Description Qty Item Refdes
# No. List
