It's pretty annoying for the guys in the shop to see a 4 decimal place number for a hole depth, when its not even critical.  For example, the default hole depth for a 5/16-18 tapped hole is 0.9025 inches.  I'd like to change that to 1.0 inches.  It will reduce visual clutter on the drawings and help the machinists take the drawings seriously.  Does anyone here know how to do this?
