The Interior Overcut is where the cut continues into the corner before retracting the blade from the fallout of the opening, such as when cutting a French Stair. 

Interior Cuts cut into the fallout of the opening, not the matboard. 

Select the desired Cartridge Tab and then the bevel type you want to edit from the Current Bevel Type dropdown control before making adjustments. Select Current Bevel Type-Front of Mat if it is being cut from the front of the mat.

• Reverse Bevel

• Normal Bevel-Front of Mat

The Interior Overcut is displayed on the Configuration Map and on the associated field as a white arrow.
