Hi Terry, > I'm not skilled in the art of PCB design, but my partially informed guess > would be 'Drilling Template' layer.
Thanks for the informed guess. :-) I think the Gerber file can contain information about a drilling layer, or if not some other CNC-related format. And ‘drilling template’ wouldn't seem to tie in with the ‘What's the state of code generation’ bit; that suggests the questioner thinks code for something could be produced. A simulator, like Spice? A test plan that can be executed? -- Cheers, Ralph. -- Next meeting: BEC, Bournemouth, Tuesday, 2020-02-04 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
