Differences
The measuring tools work
much the same way in map
and non-map PDF files, with
exceptions:
•
On a PDF map, the
measured value is stored
in a drawing markups
comment, such as a line
or polygon.
•
On a PDF map, the
shortcut menu for the
measurement types
includes options to
specify distance units
and area units.
