          will be performed in this direction until you change it.
   * To change the drawing style locally:
          From the mouse right button pop up menu choose the desired style 
          (solid, dashed, dotted or invisible ) Current element will be
          redrawing with this style.

          only length for the line while you can change both width and
          height for the box. When resizing the circle the height and the
