why the schema use 100nm not 1nm?
is it to support schema print preview that the function FitThisSizeToPaper not support wxSize(297000000,210000000)A4 in ubuntu?
Size isn’t THAT important in the schema, in the way it is on a PCB, so why have ultra-high resolution for the sake of it? 0.1mm sounds plenty enough resolution to me on a circuit diagram. How many printers do you know that can print at 1nm?
Typical printer resolution of 600dpi means dot size being 0.04mm (40 000nm).
Using 1nm resolution means replacing each of 600dpi dot with 1 600 000 000 of 1nm x 1nm dots.
