The necessity for training students to participate in developing Computer-Aided-Design and Computer-Aided-Manufacturing (CAD/CAM) System’s Software for the Industry both in Nigeria and else-where in the world cannot be over emphasized. CAD is used to design, develop and optimize products, which can be goods used by end consumers or intermediate goods used in other products. CAD is also extensively used in the design of tools and machinery used in the manufacture of components, and in the drafting and design of all types of buildings, from small residential types (houses) to the largest commercial and industrial structure’s (hospitals and factories).              CAD has become an especially important technology, within the scope of Computer Aided technologies, with benefits such as lower product development costs and a greatly shortened design cycle. CAD enables designers to layout and develop work on screen, print it out and save it for future editing, saving time on their drawings. CAD/CAM representation of a surface CAD/CAM systems use primarily two types of surfaces: Regular (or canonical) surfaces include surfaces of revolution such as cylinders, cones, spheres, and ruled surfaces linear in one direction such as surfaces of extrusion. Freeform surfaces allow more complex shapes to be represented via freeform surface modeling. Software for Virtual Reality and Computer Animation, are also presented in this paper.
