===============================================================================
Updates the dimension text format code.

      if units are in feet:
         1.      (NUM) NEW feet format code (-10, -11, -12, -20, -21, -22,
                                                                  -23, -30)
      if units are in meters:
         1.      (NUM) NEW metric format code (10-13, 20-23, 30-33, 43, 44)
      for all units:
         2.      (Y/N) update option: y-selection group, n-single entity
      if reply is `n':
         3.*     (IND) dimension text to update
         4.*     (Y/N) confirm choice

Description
This command will update the dimension text format code (the display format of
dimension data) for either a selected group of dimension texts or a single
dimension text.




Select the new format code, which represents the units used for the dimension
lines (feet/inches or meters/centimeters, etc.) and the degree of precision of
the dimensions (i.e., the number of digits after the decimal point).

Format codes greater than 0 indicate that the units are metric. The first
digit represents the specific unit: `1'  meters, `2' centimeters, or `3'
millimeters. The second digit represents the number of digits appearing after
the decimal point. Format codes 43 and 44 display the dimension text in meters,
with the millimeters (and mm in format 44) typed in superscript.

Format codes less than 0 (i.e., with a preceding `-') indicate that the units
are feet and inches. The first digit represents the presentation mode:
`1' feet/decimal feet, `2'  feet/inches/decimal inches, or
`3' for feet/inches/fractional inches. The second digit represents the number
of digits appearing after the decimal point (if any). When working in metric
units the default code is `13'. When working in feet the default code is `-30'.
The following table shows how a dimension is displayed using the various
format codes:

Format  Value
Code    (in Ft/Inch)    Text

-10     1' 7-11/16"     2'
-11     1' 7-11/16"     1.6'

-12     1' 7-11/16"     1.64'
-20     1' 7-11/16"     1' 8"
-21     1' 7-11/16"     1' 7.7"
-22     1' 7-11/16"     1' 7.68"
-23     1' 7-11/16"     1' 7.683"
-30     1' 7-11/16"     1' 7-11/16"

NOTE 1:The format codes must have two digits: the first digit must be 1, 2,
or 3. The feet/inches format codes must have the prefix `-' (a negative sign).
NOTE 2: Dimensions of window heights and sill levels (created using \mwdim),
and angles (created using \ang3p and \ang2l) will not be affected by
this command.

You are asked whether you wish to update a selection group (`y'), or a single
dimension text entity (`n'). If the reply is `y' the selection group is
updated and the update will be seen after de-selecting the group. If the
reply is `n' you must indicate and confirm the dimension text to update.

The system asks you for additional dimension texts to update until you select
another command.
