For the carton box designer, drawing carton box is a routing work, I'd like to introduce a new carton box drawing tool, please check the following photo
It includes the lines tool, arc tool, modify tool, mirror tool and other basic tools in the CAD software. It is quite easy to learn. With it you also could import the DXF format [URL="http://www.packmage.com/boxtemplates.aspx"]carton box template[/URL] into this drawing tool and modify yourself.
