ABSTRACT:
The present invention is an improved method for automatically generating chain stitching in a computer aided design system in which the shape to be filled is a complex polygon. The medial axis of the polygon is determined, concentric polygons are then constructed and sorted and the chain stitches are placed on the perimeter of the concentric polygons. The chain stitches can be used to completely fill a stitch pattern, such as an embroidery stitch pattern, or in conjunction with other stitching, such as chenille stitching in an embroidery pattern.
