convert svg to dxf command line (server)

Hello, I’m using Qcad server (paid version), I’d like to know if it’s possible to convert svg files to dxf via command line

Yes, all QCAD Professional licenses come with a simple command line utility “svg2dwg” which can convert SVG to DXF or DWG:

svg2dwg -o output.dxf input.svg

This is very basic and results depend on the type of input file used.
