CAD design software 2D-3D with different levels of functionality to the definition of the style lines, virtual prototyping modeling, series development, production management, etc.. CAD systems make it faster design and design changes. The effectiveness and advantages of the CAD system compared to the traditional methodology are amplified when the automated systems for the components production are adopted. This case of integration CAD / CAM (Computer-Aided Design Computer Aided Manufacturing) can allow you to convert projects directly into instructions for the machinery.
