Abstract
A method and system for computer aided design (CAD) is disclosed for intuitive shape control of boundary patch. A boundary patch is also known as n-sided patch which is defined by a number of input curves/edges. Continuity constraints (G, Gand G) can be specified individually for the input curves. Boundary patch is primarily used to cover a relatively flat area where other modeling operators such as loft, sweep or fillet cannot apply due to irregular shape of the area. The present invention provides a technique to directly manipulate boundary tangent magnitude of a patch and allows the user to deform the patch shape in a very intuitive way. Thus, the present invention is especially useful for industrial design applications.
