How to get better quality with PDF import?

[Christina_Girerd 73]

I just tried using the "import pdf" command for the first time, for a large existing site plan drawing (less than 1mb file, 24x30 original size drawing).  The pdf is very sharp and clear.  But the image that imported was very small and grainy, basically useless.  I got much better quality from the 8 1/2x11 scans that I stiched together and imported as a jpg.  Am I missing something for how to get better quality on a pdf import?  I'd really like to use the pdf import because it is a single image the scale and measurements are more accurate than my stitched jpg image.

 

Thanks,

Christina

The original quality of the PDF file is a large factor. A grainy PDF, I agree is useless but the fault resides in the original document. I have used PDF and image imports for years with great success and time saved but only with high quality original documents.

Good point.  I received the pdf from the client.  I will try import with a pdf I know is high quality so I can verify the issue.  Thanks.

During import, the PDF is converted to an image. That means you go from vector lines which scale as the screen size changes and remain crisp and clear(just like a floor plan view in Chief) to an image with static pixels that remain the same and give that grainy effect when zoomed or scaled.

 

Depending on how the PDF was created I've had some luck converting it to a DXF file that can then be imported. This retains the vector lines so that it can be scaled more accurately.

I did get a higher quality pdf to work better.  I'll try the dxf idea and also resizing it, doing a jpg conversion before I import.  Thanks.
