The 90° Bevel Opening is created by cutting a 90° Right Angle into the matboard.
The matboard core is hidden from view since there is no Bevel cut when cutting at a 90° Angle.
The Bevel Type refers to the angle at which the blade cuts the surface of the matboard when it deviates from the 90° right angle cut.
The Bevel Type determines the initial blade plunge position.
Select Normal Bevel or Normal Bevel-Front of Mat from the Current Bevel Type dropdown control to edit this configuration.
