how to scale a pdf of a A1 drawing

[daft vader]

I get PDF's of A1 drawings all the time some hand drawn (Paper and pencil how primative lol) that I would like to add to but when I attach the pfd's I seem to have problems with the PDF drawing being blurred, If I zoom in on the PDF drawing in model space I can get it to become clear, but when in paper space it isnt clear even when it is scaled to the correct size of A1, what am I doing wrong please ?

 

Is there a correct way of inserting the pdf in the first place ? (ie scale etc that I should be doing )

 

Could someone please go through the steps to insert it correctly

 

Thank you

First off, make sure the PDF was actually pdf'ed at scale in the first place.

 

I find that PDFs inserted into drawings are always blurry most of the time also and prefer to use images as they generally seem to work better.

Din87522 The drawing in pdf prints to scale fine if that any help ? I have converted to Tiff jpeg etc and tried them as well but no better

Insert the *.pdf (or image) into model space and add a known dimension.

Scale the image to fit the dimension.

 

However you complete the task, most always less than satisfactory results.

 

Better to draw over the image, then delete the image from the *.dwg file.

Thanks tankman, so i have to scale once the drawing is in model space not as its being inserted ?

I will try today and get back to you about how i got on
