masterfal Posted November 11, 2021 Share Posted November 11, 2021 (edited) ok so this is something that has bugged me for many years and have never been able to resolve it properly or find a proper answer so just thought i'd put it out there and see what happens i live/work in australia and use the metric system so all my cad settings (i believe) are setup to suit. yet every single time i import a pdf i need to set the scale to 2540 (1 inch = 25.4mm so its picking up an imperial reference somewhere). my question is, what do i need to do to get this import scale to be 100 or 1000 or whatever its supposed to be? Or do i have to put up with this imperial reference forever?? surely there's a way? Edited November 11, 2021 by masterfal Quote Link to comment Share on other sites More sharing options...

BIGAL Posted November 12, 2021 Share Posted November 12, 2021 (edited) The issue stems from how the original was created and it is reflecting the size of the saved pdf not a dwg size, I just did a A1 title block made a pdf at 1=1 scale then did pdfafttach at 1=1 scale it appears to be spot on. There is some posts about getting info from a pdf so size may be one of them then could write a lisp to do the pdfttach and rescale as required. Also remember say the plan may have a scaling factor for the viewport say for a house like 1:100. This may be the problem it can be inches, look at the mm.

SLW210 Posted November 12, 2021 Share Posted November 12, 2021 Same here when imported to an Imperial and Metric drawing. The PDF was plotted to Imperial scale is all I could say, perhaps contact the source. Though easy enough if they are all the same to set the import scale to 2540.

BIGAL Posted November 13, 2021 Share Posted November 13, 2021 I had a look via Ghostscript whilst could not get it to work there are 2 sizes in a pdf from what I could see. Looks like your problem. Quote Link to comment Share on other sites More sharing options...
