When I import a high resolution landplan into sketchup resolution gets obliterated, how can I avoid this?

Hi Simon - just a question - Why export to a PDF when you could have exported to a JPEG and probably gotten a better result? I’ve attached a Photoshopped doctored JPEG of a TIFF of your PDF that might be closer to the original . . .
Thanks for all the discussions on this subject - will be very worthwhile to me in the future !
