Hi Danny, unfortunately PDF is a very complex format with all kinds of various chunks of data strewn about the file in different structures and with different kinds of compression applied to them, all kinds of stuff like that. There are a lot of different possible ways the current MoI PDF reader can get confused when trying to get at the stuff in a PDF file.

In the future I want to do an overhaul of that area and probably license a PDF reading library so that it will work better.

In the meantime, Rhino is able to read this particular PDF file, so I have converted it to 3DM that way, I'm attaching the converted 3DM file here for you.
