Hi eric,

It's likely to be that the pdf file only contains bitmap image data in it and not vector drawing data.

When you open the pdf in Adobe viewer, if you zoom into areas does the display stay crisp like a vector drawing does, or do you see it getting blocky because it's made of pixels?

MoI and Rhino both only try to read vector drawing data out of a PDF file.

If there is no vector data in the file then converting it to a PNG or JPG image and bringing that in as a background image would be the way to go.
