When we think of Computer Aided Design and Drafting (CADD), certain questions arise that we never think of while working on the drawing board. We do not use the essential drawing board tools: paper, pencil, T-square,Protractor, compass, eraser or scale, yet still have to design or make a drawing. When even one of these tools is missing we know how frustrating it can be. With CADD we don't need even one of them! CAD/CAM/CAE always had been a truly useful tool in Engineering Architectural field & Manufacturing. CAD/CAM/CAE is used in all branches of Engineering, Architects, Manufacturing companies, Construction companies, Oil companies, Drawing & Designing activities, Map Companies, Government Departments, Archeologists, Aerospace, Automobiles, Engineering / Diploma Students & Professionals connected with this industry. It is certain that engineers will get an employment or career growth.
