The Units popup specifies the format of the suffix of a length value. You may choose None, Units, Abbreviation, or Punctuation. Punctuation applies only to feet,inches, and degrees.

The Form popup specifies how numbers should be displayed, Decimal, Fraction, Feet/Inches or Alternate. Alternate provides for decimal representation showing the primary units as specified on the Scale palette for the whole drawing and the metric/inches value in parenthesis.

When one graphic is selected, and that graphic has a defined area, this area is reported in the Area text field below all other reported details for the graphic. This area value is not editable, it only reports the value. The precision and units settings follow those defined for lengths on the Graphic Details Inspector.
