I am printing the control surface picture to use that for the drilling marks, but because I don’t have any required applications, from that small image at ucapps… I would like to know what are the exact proportions to keep the front panel 1:1 with the holes of the circuit boards…
if you mean the Schaeffer panel, use Front Panel Designer, and hit Ctrl+O which brings up the object properties window. then, click on each hole in turn and it will give you measurements from the bottom left corner of the panel.
