Hi Danny - that's correct normally just a scan converted to PDF won't work because the PDF file will contain a bitmap rather than vector line/curve data.

One way to tell is to open the PDF inside of the Adobe reader, and zoom in on some pieces of it. If when zoomed in it looks all jaggedy like this:



Then that means it is a bitmap in the PDF file, like the same kind of data as in a JPG file.

You have to run something like that through a vectorizer converter to turn it from a bitmap into lines and curves, either that or save it as a bitmap file and use it as a tracing guide with View/Image in MoI.
