Claim:
1. A non-transitory program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform method steps for morphing one or more CAD design elements to one or more morphed CAD design elements, said method steps comprising: receiving one or more design elements; identifying one of the one or more design elements as a selected design element to be morphed by defining boundaries encapsulating the selected design element; defining a plurality of points within the selected design element; grouping the plurality of points into a plurality of groups of points; selecting one or more of the groups of points as control groups of points, wherein the control groups of points are not morphed; selecting one or more of the groups of points as deformable groups of points, wherein the deformable groups of points are morphed; selecting a plurality of the groups of points as fixed groups of points, wherein the fixed groups of points are used to establish morphing equations; defining boundary curves using the groups of points along a boundary of the design element; creating an infinite surface with the boundary curves for each of the groups of points having more than 4 sides; creating a Coons patch with the boundary curves for each of the groups of points having between 3 and 4 sides; and trimming the infinite surface along the boundary curves to create a plurality of morphed surfaces; and regenerating and combining each of the morphed surfaces to create a morphed design element.
