Hi, I have just installed Svg2Shenzhen and everything seemed ok.
On extensions -> Svg2Shenzhen , the option “prepare document” is grey, I can’t click. I restarted inkscape twice, and the notebook once. I tried with a new document and a existing file. All the same.
@badgeek hasn’t been around for awhile but just going from the dates on github the code may be current. I don’t see a version number. Does it expressly say it is compatible with Kicad 5?
If Possible can you try the same with downgrading your inkscape from 1.0.2 to 1.0? I think after @badgeek fixed things for Inkscape 1.0 there are two version released by Inkscape.
