Hi,
I'm laying out a PCB with a UBGA (0.8mm pitch) IC. I routed all of the escape paths by hand but wanted to use the autorouter for the rest of the board.. I want to remove the auto-routeds part of the board without unrouting each route by hand.
Is there a function that I can use to unroute just a section of te board.
Thanks.

Easy to use and quick to get started.
