In art, the term is used to refer to the continuous line in continuous line drawings which is unbroken from the start to the end of the drawing.  In this drawing, continuous lines are created by without taking the drawing instrument and gaze from the drawing surface. It is an artistic method of drawing and generally used to highlight the quality of the picture other than the pictorial elements. The drawing is created with one unbroken line. Any device that allows free flowing line can be used for this drawing. Pencils, felt-tip pens, and brush are normally used. It is also known as blind object drawing or unbroken line drawing.
