I'd like to understand something about specifying slots milled into a commercial enclosure (I use Kicad as the EDA side, and the PCB was genertaed via the KicadStepUp workbench).
My contact (at the PCB assembler) uses another company for this. I've been told that 2D PDF or preferably DXF/DWG can be used.
I don't know how (or if) this relates to the Freecad Path Workbench - but maybe I don't need 'gcodes' etc for simple '2D' slots through a surface?
One thing that seems clear is I'd have to specify a datum point.
The accompanying image shows where I'm up to - I still have to define some 'pockets' thugh the aluminium enclosure. For instance, there could be a rounded rectangular aperture to accomodate the 6-way header.
