Abstract
The invention described herein is a method, system, and computer program product for the design and fabrication of the surfaces of an object. The process begins by using a CAD process to design surfaces of the object. In particular, the surfaces are modeled using developable surfaces only. The intersections of the developable surfaces are then calculated. Any excess surface area of the developable surfaces is then trimmed. The boundaries of each developable surface are abstracted to produce a two-dimensional planar model of each developable surface. From each planar model, a full-sized two-dimensional shape can then be fabricated in proportion to the planar model. Each fabricated shape can then be bent in accordance with the corresponding developable surface of the CAD model. Finally, the edges of the fabricated shapes are attached as determined by the calculated intersections of the developable surfaces of the CAD model.
