Inkscape: error when converting PDF to dxf

T by theoryshaw on 5 May 2021, edited 10 May 2021 #

Can anyone convert the following PDF to a DXF?

I used Inkscape, but got the following error, which I don't know how to overcome.

Anyone have any pointers?

Another tool to convert PDF to DXF is pstoedit. My batch script:

#!/bin/sh

for PDF

do

DXF=`echo $PDF | sed 's/\.pdf$/%d.dxf/i'`

pstoedit -f "dxf:-polyaslines -mm -ctl" -split "$PDF" "$DXF"

done

I tried with Inkscape and didn't get any errors, but the final DXF file looked messed up with a bunch of blocks in the top right. I recommend filing a bug for the Inkscape devs?

Then I tried using an older method I've documented here: https://thinkmoult.com/how-to-bulk-convert-pdf-to-dxf-or-dwg.html and I got much better results:

I've attached the file for your convenience.

Here you are.

I opened the PDF with Scribus (I think it has more robust libraries to work with PDF files). Then I exported the file as SVG. Later I opened the SVG file with Inkscape, I ungrouped the image (no sure if it is necessary) and exported the file with Save a Copy, DXF 14.

Do you know SolveSpace 3.0 is able to import DWG files?
