  • Method of making a unified interior and exterior design verification model
    Patent number: 5231749
    Abstract: A method of making design models allowing for CAD data verification of interior and exterior styled surfaces comprising the following steps. Initially, the interior and exterior surfaces of the proposed design are mathematically modeled. A series of separable parts of said design are defined. At least one bench mark plane is provided within the interior and exterior surfaces of a first part of the design. An exterior surface is shaped on an exterior portion of the first part of the design. Likewise, an interior surface is shaped on an interior portion of the first part of the design. The interior portion and the exterior portion are separated from each other at the bench mark plane when the interior portion is formed. The interior portion and exterior portion are assembled together at the bench mark plane. Finally, the separable parts or modules are assembled together at the boundaries. The method further allows for the disassembly of particular modules and their modification in holding fixtures.
