Parametric design is a modem approach to product modeling, which associates engineering knowledge with geometry in the product model by means of constraints. Together with the technique of feature based modeling, it has widely affected the development of new CAD-systems.
Parametric design is a method in which few variables or parameters control the remaining parameters in the design. When a value is entered for the control parameter, the software should automatically calculate the remaining parameters and creates a finished CAD drawing. As a result, any changes or modifications to the design using the parametric technique will be done quicker than redrawing required by the traditional CAD. In this project, a cabinet was designed and modeled using the parametric design technique.
