ABACOM - ELECTRONIC SOFTWARE

I came across a neat front panel in PCB material (Gerber and drilling files), it had a cut out for a display and was finished with black solder resist and white lettering on the front, and plain tinned copper screening on the back. The files produced a very nice panel for little cost from JLCPCB.

How can I produce a rectangular cut-out (hole) in a PCB with Sprint-Layout?

Thanks
Dave
