PDF3D ReportGen and PDF3D.IO development SDK can be used to convert a variety of geospatial formats to 2D or 3D PDF.

Within the PDF3D ReportGen “Conversion” tab, there is a selector drop-down to set the output PDF units. “Model Units Type” specifies output units i.e. target output PDF file units used by Adobe Reader.

Also if you intend to measure in a 3D PDF viewer, we recommend on the Advanced tab, disable “Perform Scene Normalization”.

    <ModelUnitType value="ModelUnit_is_mm"> 
        <GeoOutputCS utmZone="1" utmBand="NorthHemisphere" gcs="WGS_84_epsg_4326" geoRegistration2DMethod="ISO" system="Automatic"/>
    </ModelUnitType>
