摘要： A method is provided for the creation of an addendum for use in the design and production of sheet metal formed components, which method uses a sectionless approach. In a preferred approach, elevation curve (EC) lines are established relating to the component (ECc) and binder (ECb), and it is these lines which are used to design the addendum. Additional EC lines (EC1, EC2, EC3, etc.) can be added to modify or optimize the addendum design. The spaces between the EC lines are filled using various parameterized filling techniques so as to provide the addendum design. Optimization of the addendum can be achieved by modification of the various EC lines, so as to modify or control the various design parameters, in accordance with various quality or design criteria. A more rapid, and less complicated approach to addendum design is provided.
