#-------------------------------------------------------------------------------
# This is a Microstation V8 Unit Definition file.
#
# Lines that begin with # are for descriptive comments.
#-------------------------------------------------------------------------------
#
# The active unit definition file is specified by the configuration variable
# MS_CUSTOMUNITDEF.  By default that variable refers to:
#   \Bentley\WorkSpace\System\data\units.def
#
# MicroStation uses its active units definition file in two instances:
#   1) To provide information about non-standard units for use in converting
#      data from file formats with incomplete unit information.  For example,
#      V7 dgn files provide only a two character unit label.  This two character
#      label is compared to the labels supplied in the units.def file to
#      determine the correct mathematical definition.
#
#   2) The units defined in the units.def file are available during a 
#      MicroStation session, and can be accessed similiarly to the standard 
#      units.  For example, they are accessible via the "SET UNITS" keyin.
#
# NOTE: In both of the above cases, when a unit from the unit definition file
#       conflicts with one of the standard units, the unit from the definition
#       file will be used.
#
# The format of this file consists of one unit definition per line, where the
# format of each line is:  
#
# Label,Label,...,Label; Name(singular); Name(plural); Numerator; Denominator; Base; System
#
# Label:
# Used to specify the default label for coordinate readout and dimensioning.  A list of 
# labels can be provided but only the first is used by V8.  The other labels are used 
# when loading a V7 format file, in which case the label for the V7 file's master unit 
# will be matched against all the labels that are provided.
#
# Name(singular) and Name(plural):
# Used for display of the unit in dialog boxes.
#
# Numerator and Denominator:
# Together these are used to define the size of the unit being described.  The ratio of
# numerator divided by denominator represents the number X of the new unit that make
# up a single Meter.  For example: 100.0 / 1.0 = 100.0 centimeters = 1 meter.  To ensure
# the greatest possible accuracy, it is highly recommended that both numerator and
# denominator be specified as whole integer values.
#
# Base:
# Only units of the same base can be compared.  All linear distance units should use a
# base of Meter.  For nonlinear units such as degrees latitude or longitude specify
# base Unitless.
#
#   Valid values for Base are:
#   0 Unitless
#   1 Meter
#
# System:
# Used to catagorize units for display in some dialogs.
#
#   Valid values for System are:
#   0 Undefined
#   1 English
#   2 Metric
