[sudo-discuss] DXF or SVG or? for scanner light fixture mount cutting for book scanner

[jacques revera]

Which format?

"Jonathon will send us the design files for the sockets mounting plate soon
as I tell him what format we need to cut it at the SUDO room: DXF or SVG or
something else?"

I don't know anything about the machinery available at SUDO room or these
kind of file formats.
