Hi Sir,
I need to parse the DSN file which came fro PCB->EXPORT->ROUTER. In the begining of DSN file, there is a coordinate,like below shows. it looks like 4-corners of board outline but it has little difference. for example, the lower-right corner of actual board is (-57.15, 0). so I am confusing what the below coordinate is, is there anyone expert can help? Thx
(constant pcb_xlo -57.1000)
(constant pcb_ylo -1.9100)
(constant pcb_xhi 110.4000)
(constant pcb_yhi 111.1000)
