Abstract

A tracing operation by designating a region is performed after a wire limit. Tracing line segments (2a, 2b, 2c) parallel to the wire limit (1)are found connecting a plurality of points. The tracing operation is performed by moving a stylus on a path along the tracing line segments (2a, 2b, 2c), whereby a tracing region determined by a complex wire limit can be accurately traced.
