A parametric and constraint-based design system

Parametric and constraint-based design systems are becoming the CAD/CAM standard in most commercial applications. The ability of these systems to create parametric models allows engineers to produce designs that can be modified to fit changing requirements. Current industry product cycles and development times require fast response from engineering to the changes that inevitably occur with new product introduction or product re-design. This project discusses, demonstrates and implements a parametric, constraint-based design package and justifies its use in a design environment. This analysis of constraints extends into an examination of the principles behind constraints and their effects on geometry within a predetermined space.
