Here is my example .svg file
Thanks Rick, that I can upload this
In the meantime Ralph contacted me and he has helped me already quite a bit (thx Ralph). He discovered that a PDF file from Vectornator “contains the square with a stroke and no fill, and also a square with a white fill and no stroke (when he looked at the data in Adobe Illustrator). What Ralph did in Lightburn was select all and delete duplicates”
that’s a major step forward but I’m still looking for the option within Vectornator to turn off the white fill if I don’t need it. To be continued. …
Also I’ve tried several .svg to dxf online convertors to import it in Lightburn as a dxf (like Convertio, cloudconvert, anyconv and freefileconv), but just as Inkscape they change the aspect ratio.
The only convertor so far which keeps the aspect ratio ok is www.svgviewer.dev This online tool optimizes .svg files but removes the layers option.
Ralphs suggestion was to use the .pdf export function within Vectornator. However with both svgviewer and pdf I lose a lot of functionality. And it remains strange that Lightburn gets stuck
