qcad has a parts library as an addon package (various images of parts that can be used in a drawring). link of the file http://www.ribbonsoft.com/archives/partlibrary/partlibrary-2.0.1.2-1.zip http://www.ribbonsoft.com/qcad_downloads.html The zip file has no info about license also no info on the site. To install the files just extract the zip file and copy the contents of the folder partlibrary-2.0.1.2-1 in to /usr/share/qcad/library (nothing else is needed so as to accessibele from the application) Also there is documentation in other languages than English (German, Czech, Hungarian).
I am of course aware of this. However should probably go into new package and would need to pass the Fedora Extras review process. So someone needs to file a request for review.
