If you search around for ideas on how to import DXF files into Inkscape or convert DXF files to SVG files, there are a lot of results. But they mostly seem to be shareware or orphaned applications that haven’t been updated for years. However there is a simple, obvious (once you see it) and free solution to converting DXF files to SVG files (which Inkscape can load).

It’s called Open Office Draw.

Yes, that’s right. Open Office Draw can load a DXF file and save an SVG file. I’ve tried it and it worked – I was able to take a DXF file, convert to SVG, load into Inkscape, edit, save as DXF (see my other posting from a couple of days ago on this) then load into CamBam for CAM processing.
