Changes in geometric model parameters are constant throughout the design process. Each group in an organization needs different model information at varying times during the design process. As a result many different models of the same part or assembly arise for the needs and use of each group in each design phase (from conceptual design to full product definition). When one group makes changes to a model, those changes need to be reflected in all of the models which describe the product in all groups and design phases in order for those changes to be verified against all design criteria that were set, and for those changes to be seen by downstream users in the design process. This thesis describes a method for linking these models together which will provide revision control, assuming all models can be updated from any of the other models which define the product and allow for these models to be parameterized using different schemes.
