Managing Contingency in Parametric Models through Implicit Relational Modeling

Modeling and maintaining relationships in a parametric model compounds the work of the designer. When major changes in design direction take place, the work invested in the modeled relations is often lost. We contend that an implicit relational modeling approach provides for loosely coupled relations between the 'parts' of a design and mitigates the loss of work that occurs when changes take place. In our implemented system, implicit relations participate in a pattern of interaction known as the Dynamic Proxy.
