The 90° Bevel Drop is created by cutting a 90° Right Angle into the matboard. The matboard core is hidden from view since there is no Bevel when cutting at a 90° Right 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 for the 90° openings is the form of opening cut and determines the initial blade plunge position. The Drop is one of the categories within certain opening styles, like the initial section cut of an Open V-Groove. However, it cannot be chosen as a standalone bevel type within Designer. Select Normal Drop or Normal Drop-Front of Mat from the Current Bevel Type dropdown control to edit this configuration.   See: 90 Degree Bevel Drop Configurations |
