The measuring units in a PDF file created with pdf.pltcfg are in miles. The desired units are design file units.
When a Geographic Coordinate System (GCS) is present in a design file and “Enable Georeferencing” is On in pdf.pltcfg, the PDF will always use the GCS to measure distances.
Setting “Enable Georeferencing” Off and “Enable Measuring” On will measure in design file units.
Setting “Enable Georeferencing” Off and “Enable Measuring” Off will measure in inches.
