I use a CNC Machine Software which detects positive or negative bend of sheet-metal part based on the colour of bendlines in the flat pattern dxf.(Green colour for positive bend and Blue colour for negative bend). I create Solidworks drawing file and then export it to dxf with mapping enabled for separate layers of positive and negative bendlines. But every-time the bendline’s colour in the generated dxf is found to be of only ONE colour though there are both type of bends in the part. If anyone knows how to export dxf with two coloured bendlines for different directional bends then kindly help. Thanks in advance.
