I am having a hard time remembering where to change the diameter of a lock hole.  Currently our National Cam lock setting is routing a 7/8" hole, I need this hole revised to a 3/4" hole.  I've been looking in the Lookup Tables, but the only formula in there is a =ROUND(.0625*Unit_Factor,Accuracy).  This leaves the 5 - Hole Diameter Field at 0.0625.  

Where do I change this in order to get a 3/4" diameter hole?
