In CAD, generally the drawings are done according to the dimensions given either in a hard copy like paper or it may have been mentioned in a raster or image file, which is a scanned copy of the paper drawing. If the source drawing is a hard copy, then putting the hard copy by the side and referring to the same does the drawings. But this is a cumbersome process. So another process has been developed in which, the hard copy is scanned and the same is attached into the drawing platform say, Auto CAD. Then it becomes easier to draw the elements. This type of draughting is called as on-line draughting
