A Parametric Feature-based CAD System for Reproducing Traditional Jewelry

We introduce an automated parametric CAD system for the design of pierced medieval jewellery, where the design of a piece of jewellery is expressed by a collection of parameters and constraints and the user’s participation in the design process is through the definition of parameter values. We present an approach to designing traditional pierced jewellery using a voxel-oriented feature-based Computer Aided Design paradigm: a large complex pierced design is created by appropriately placing elementary structural elements. We also present a scaling algorithm for enlarging pierced designs without altering the size of the elementary structural elements used to construct them.
