I have been working to try to make this tool work for my Fusion 360 files, however it appears to always read the files upside-down and backwards and even after following the SVG template as shown, it writes it back onto the original in a strange, mis-scaled and backwards form. I don't really know what's happening here but I'm relatively new to this program.

It's a bit hard to see, but you can see it writes the drawing from the SVG template in the bottom-left corner, very small, and vertically mirrored. It doesn't look like it's any immediately obvious scale ratio, definitely not a metric-imperial issue. Still experimenting but very confused here.
