Abstract
The present invention is an improved method for automatically generating chenille filled embroidery stitch patterns and/or claim stitching in a computer aided design system in which the shape to be filled is a complex polygon. Concentric polygons are constructed, such as either by using the medial axis of the polygon or by constructing offset elements and joining arcs without use of the medial axis, and sorted, and spirals are placed along the polygons with stitches being placed along the spirals. For chain stitching, rather than placing spirals, the chain stitches are placed on the perimeter of the concentric polygons.
