Sorry. bothering you again. I have one more question, what are the below data (Boundary Rect and Boundary path ) mean? Thanks in advance.

(structure
(boundary (rect pcb -65.4750 -13.2110 118.7750 116.7505))
(boundary (path signal 0 -33 12.8000 -33 9.3500 -28.9400 9.3500 -28.9400 1

It's the ROUTE KEEPIN shape -- not the BOARD OUTLINE

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)
