Shoe uppers are often constructed of panels which overlap one another and which may or may not have been thinned along the periphery. One of the visual features important to aesthetic shoe CAD is the profile variation along the panel boundary caused by either stitching or compressed gluing. Based upon an understanding of geometric requirements, the following issues are addressed: offset curve generation according to a classification of local geometry of an arbitrary 3D surface patch; cross section type handling; profile representation and rendering.
