A knowledge-based cad modeling paradigm for indian traditional filigree jewelry

Abstract

The present work aims to develop a knowledge-based parametric CAD modeling system to create Indian traditional filigree jewelry designs. Today, developments in CAD technologies are towards reducing the time and efforts of designers required in modeling. Indian traditional Filigree jewelry is delicate metal craftwork representing twisting or curling of pliable wire and shows the beauty of local craftsmen’s traditional workmanship involved in making this type of decorative embellishments that result in a very precise and delicate model. Traditional craftworks involve much skill, effort, and time, so upcoming generations are not interested in their respective traditional works. The traditional knowledge base of Filigree jewelry is incorporated in the CAD system's programming environment by defining some shape grammar rules and logical rules to control jewelry attributes. Parametric modeling has great potential to develop customized CAD tools for automation in generating 3D models of handicraft products in a virtual environment. By using knowledge base rules, geometrical models can be designed beyond a conventional design. This knowledge-based jewelry modeler is developed using the Microsoft Visual Basic Programming environment in SolidWorks API.
