Hola, go to cabinet editor (don't load a cabinet) and load a 12" x 12" 3/4" Generic display panel. Take it to the part editor, then contour editor. Draw a straight horizontal line near the top, ~10" long (not critical). Click Offset, and create a duplicate ~8" below. Now (making sure object snap is on) connect the two lines to form a rectangle. Click Radius, set to 1", then attempt to radius the four corners. On both of our design computers, we get the attached message. ("cannot fillet the bodies, because they do not intersect")
