My mistake. I meant svg2shenzhen when I said “svg2mod”.
I understand the resistance to having to learn another CAD package (FreeCAD in this case), but the StepUp plugin is so powerful (and originally designed for your exact issue) that you shouldn’t need to learn more than the basics in FreeCAD (which can be a struggle in itself) to use the StepUp plugin. Search this forum for StepUp to find some demonstration videos of footprint generation. There is one that I can think of showing how to go from a STEP file downloaded from a manufacturer to a footprint in KiCad. Found it, see this post: KiCad StepUp: The Sketcher for Footprint generation - #18 by maui
I’m not advocating you abandon Fusion360 for FreeCAD, simply using it as glue in your workflow.
