DEFINE BOX AND SHOW BOX
The DEFINE BOX function is used to define a specific box-shaped volume around the drawbead. The box contains the drawbead nodes and elements between the bead and the outer edge of the blank. It is implemented to limit the size of the master surface for the drawbead contact. The BOX SIZE is the linear distance between the drawbead line and the surfaces of box. The SHOW BOX function is used to graphically display the draw bead boxes that have been defined.
To define/show the drawbead box, the user has to toggle ON the DRAWBEAD BOX, then key in the box size and click the SHOW BOX button to display the drawbead box on the display area.
