A method, system, and apparatus for preparing geometric models for use in a design tool are disclosed. The method comprises generating a first base shape model, separating the first base model into components, and characterizing the components. Further, the method provides for comparing the second base model, similarly prepared and characterized, to the first, and adjusting the features used to characterize the base model components until the two objects can be placed in correspondence. The system comprises a processor capable of processing instructions for generating base shape models wherein the processor is capable of processing instructions for separating a base model into components and further capable of processing instructions for characterizing base model components. Accordingly, the method may provide for defining a geometric model template by adjusting a base model to match a succession of input models.
