Does anyone have any comments regarding how close a plated or 
     non-plated hole can be to the routed edge of a PCB.
     
     What is the typical recommended minimum.  I've been told that a plated 
     via and associated copper can be down to .010" to a routed edge.
     
     I have personal concerns about how close a via can be before the 
     routing process may damage a via.  Additionally the slop associated 
     with the routed edge location.
     
     I'd appreciate any feedback.
     
     Thanks,
