As I try to wean myself off Inkscape in favor of Affinity Designer There are a few things I cant seem to adapt to my workflow. When I import the SVG produced from Boxes.phy I get a blank embedded bounding box. I have tried applying fill and line attributes to the selection, but I still end up with an empty object.
I also have a hard time getting around the “embedded document” workflow they use. It would be great if there were a way to flatten the file so the embedded documents weren’t layered. Copying an pasting between and embedded file and the main document always results in a scaling problem for me.
