Abstract
A line recognition adapted for recognizing a drawing in which a plurality of lines overlapping one another are indicated by a given one of the mutually overlapping lines and overlap symbols representative of the other lines. The overlap symbols are so configured as to give information as to line kinds of the other lines such as solid line, dash line and chain line and/or information as to colors of the other lines. The paths of the other lines are estimated on the basis of the overlap symbols as well as the positions at which they are inserted, for thereby recognizing the whole line paths or patterns of the drawing.
