UPDATE changes some attributes of dimension entities to
the default you set in DETAIL, SET, TEXT function. The
following attributes change.

NOTE and LABEL entities:
   Height
   Font
   Slant
   Fill

DIMENSION entities:
   Height
   Font/Slant/Fill
   DIM REP
   Dimension scale
   Trailing and leading zeros
   Tolerance mode: for example, NONE, -/+, LIMIT
   Tolerance values
   Character Aspect
   Units

HINTS

* Updating attributes such as character height and 
  character aspect ratio expands or contracts text size.

* Tolerancing does not affect ordinate dimensions.

* For manually entered dimension text, UPDATE changes the
  dimension height and font.

* When updating the dimension scale for linear, radius, 
  and diameter dimensions, CADKEY applies the current 
  scale factor to the original dimension value.
