Cad Software
Cad is used to design products. These can be goods used by end consumers or intermediate goods used to make other products. In the manufacture of components, tools and machinery are used. CAD is also used to design these. Originally computer languages such as FORTRAN were used to develop Cad Software systems. Now, object oriented programming methods use objects and their interactions to design such applications and their computer programs. These programming methods are widely used now-a-days, not only for CAD, but for a host of other applications.
