A test board with every track, via and pour deleted while the parts stay where the human placed them. The router gets the blank problem; the human routing is the reference.
How it looks
Real geometry: CORE3588 copper, drawn from our board file (2D plan view)
As Sam routed it: CORE3588 top layer, 22 x 24 mm around camera sockets P3 and P4.
1Sam's tracks and vias: the human routing we keep as the reference answer.
Real geometry: CORE3588 pads, airwires computed from our board file
The same area, copper stripped: what the router gets.
1The parts stay exactly where Sam placed them...
2...but every track, via and copper pour is deleted. What is left is the problem: pads and airwires.
