PDF Options

This checkbox is active by default: when you save a project in PDF format, the PDF retains the ARCHICAD Project Info data (entered at File > Info > Project Info). This can be read in the PDF’s Document Properties (File > Properties).
It can be useful to uncheck this box if you do not want the PDF to display e.g. the Architect Name (as the Author shown in the PDF Document Properties) - for example, if the PDF is to be submitted as part of an anonymous competition.
For more information on the PDF/A standards, see: ISO 19005-1:2005 Part I: Use of PDF 1.4 (PDF/A-1) and ISO 19005/2:2011 Part 2: Use of ISO 32000-1 (PDF/A-2).
The Arc resolution setting reflects the fact that the PDF format does not recognize arcs/circles and must approximate them by converting them to polygons. The Arc resolution setting defines the accuracy of these polygons.
Limit image resolution to: The maximum image resolution of the images saved to PDF. Images whose resolution is less than this limit will remain as-is.
Compress all images: All images will be converted to JPG format, which entails a compression to 80%.
