1. In a computer aided or generated graphics system, a method of graphical representation of a two dimensional form of uniform width on a display media, comprising the steps of; providing a set of data points generally located along a longitudinal center line of the two dimensional form; converting said data points to second sets of data for second or higher order parametric equations which define a plurality of adjoining curves that closely approximate said center line; converting said second set of data to a plurality of line segments closely approximating each of said adjoining curves; defining for each line segment four vertices of a rectangle having a predetermined uniform width, each of said rectangles being divided by its associated line segment into two generally equal portions, said rectangles generally defining the two dimensional form; smoothing the junction of said rectangles; and recreating a graphic representation of said two dimensional form from the smooth rectangle data.
