I use SVG designs to create cut files for home hobby cutting machines such as Cricut or Silhouette Cameo. If I'm using text in my designs, I have to convert the text to curves, ungroup the letters, and then Add them in the Geometry panel. This is especially important with script fonts as they overlap. As well, all objects have to be curves in the design before exporting them for cutting.
I'm attaching a screenshot of my SVG export window that works just fine for my purposes.
I sought out this forum again this morning since I decided I wanted to create rhinestone designs which make it imperative that the design maintain the size through the export process. So far my test documents have worked to within ~0.01 of an inch when exported using this preset. Fingers crossed it will work when I figure out how to create my rhinestone designs in Affinity Designer. I've only been using AD for a couple of months after years in Inkscape.
