Hi, here's a quick port for QElectroTech (cf https://qelectrotech.org/) - an electric diagram drawing tool, a bit like dia or kicad or qcad... it features a huge database of already known electric symbols, examples display fine here.
Afaict the databse and the code is available under GPL. Put it in graphics/ category, maybe cad/ is more suited. feedback and oks welcome. Landry
