Lens size (mm)
Now just create a Free Camera in your scene, tick the Orthographic Projection box, change the Lens mm to match this dialog, and make sure Target Distance is 13'4". In the Render Setup Dialog, be sure Output Size is set to Custom, Aperture Width(mm) to 36, and make the width & height match your selected paper size at your desired resolution (e.g. ARCH B landscape @ 300 dpi would be 5400 wide by 3600 high). (NOTE: The resolution [PPI] is irrelevant for this application) Adjust your camera position, optionally select Area to Render>Region, and click Render. Enjoy!
