 One consideration is that QCAD itself
https://www.qcad.org/en/qcad-documentation/qcad-features has a $$$
"Professional" version -- and the open source portion has to have the "pro"
extensions stripped from it to be validly distributed. LibreCAD was a fork
of the "community edition" into which CAM control was added. That's only
available in the $$$ QCAD. So the original core functions were the same for
both. LibreCAD becoming an open source (partial) replacement for the
professional QCAD/CAM.

 Both have since been updated to use QT5. https://librecad.org/ However,
the QCAD builds are for Intel/AMD processors. You'd have to download the
SOURCE of the community edition and build it yourself to get an ARM
version-- which also requires the build environment for QT5... And that
source is what was the start of LibreCAD.  (interesting, the prebuilt
builds seem to use QT5 only on 64-bit Linux, the others are still QT4)

 The feature list for QCAD (see above link) has EXPORT to PDF, but
doesn't mention IMPORT from one. (The professional version has DWG to PDF
command line batch converter).

 And https://inkscape.org/about/features/ doesn't mention importing a
PDF either, but does mention export. However, the "manual"
http://tavmjong.free.fr/INKSCAPE/MANUAL/html/File-Import.html implies there
is some capability.


{Okay -- pricing is only $$, not $$$ for single user; 33Euro for QCAD Pro,
89Euro for QCAD/CAM... Including one year of updates; but still limited to
"big machines", not ARM}
