PDF refuses to properly convert to DWG any ideas why ?

[mailZU2NV]

I have this pdf which once converted to DWG by PDFIMPORT becomes like on the photo below. I don't understand why, is the quality too low ? I have successfully converted similar quality pdfs, should I upload the PDF as separate file ?

In case you need it, I will upload the PDF as well.

The PDF document has been scanned rather than created directly from a CAD package. This means it contains only rasterised pixels rather than any line information.

So I am out of luck here ?

You could bring it in as an underlay and trace over it...

AutoCAD Raster Design could help in this case. You can vectorize raster image. Remember: accuracy depends on raster image quality and resolution.
