# Content: MacTavish Standard Aperture List
# Date: Wed Sep 26 22:29:00 1996 EDT

# This list establishes the MacTavish standard assigments of
# aperture purpose, shape and size to Gerber D codes.  Once an
# assigment has been made, it is very important that the
# assigment never be changed.  If additional apertures are
# needed, assign those apertures a unique D code.  Printed
# circuit board manufacturers are likely to assume that a given
# code is used for the same purpose from job to job.  Reassigning
# a D code is almost certain to cause the improper manufacture of
# a board.  PCB manufacturers should always be certain that they
# are using the current version of this table.

# Systematic aperture codes:
#	D1sss - Flash aperture codes
#	D2sss - Draw aperture codes
#	D3sss - Drill aperture codes (finished hole size)
#	where sss is the aperture size is mils.
