Actually Scott I believe you are the one that is wrong. Everything round that I have ever worked with the bend radius was always to the center line, So that makes the routing program correct. Flat parts like sheet metal goes to the inside radius, but not rounds like pipe tubing and wire.
When discussing the minimum bend radius it is the inside of the bend not the center of the bend. Google it.
"Minimum bend radius of wire"
We have international documents which spec out this fact.
