If I would start right now a story about papyrus and languages and numbers what would you think of? You would probably guess that I'm going to give you a history lesson. And it's true in one way or another, but do you have any idea which would be the issue of this history lesson? Computers! But please don't be surprised because the history of the modern computers has started once those people were looking to create machineries to help them calculate and solve problems. It was the papyrus used to write down numbers and data which evolved into the abacus and obviously, from then till 1946, when ENIAC was launched and described as a machinery for calculating the firing tables used by the US artillery, it's a long way indeed. But now computers are everywhere and you might have no idea how many great things we can do just by using them. Still, one of these great things its called computer aided design, shortly known as CAD or CADD. People hired to work in the CAD or CADD departments have to do everything from designing to drafting of the project assigned to them.
What is CAD?
I'm sure it's not enough to say that CAD comes from computer aided design. I should add that CAD is the specialized software designed to create a drafting process plus a manufacturing and a documentary one, with the help of a computer and some special tools. When purchasing this software you should be able to design things in both 2D and 3D formats with all the details like curves, figures, surfaces, solids and so far and so on. Its importance is high, especially in domains like shipbuilding, industry, architecture, automotive or aerospace because it works with vectors.
Career Opportunities
Fortunately, for those who are really passionate about CAD, there are a lot of entry jobs available that they can get with only a high school diploma, some math classes or even technology, sciences or something else related and a portfolio with your previous work. The rest of the instruction process will be made at the work place, if you manage to impress your potential employer.
The main directions on which someone could obtain job in CAD are: CAE and FEA, which involves analyzing of finite elements along with engineering with the help of a computer, CAM and CNC, which is the manufacturing industry based on the aid of computer and includes instructions for the machines used by the so called computer numerical control, PDM or Product Data Management, where there is the field of management, revisions and controls for documents and the last one is where there is a render of realistic photos.
Importance
Only by looking at all the categories from above, you will understand that computers play a huge role in the process of designing and building. With the help of some CAD programs, you can virtually build anything you want or need by recreating the real final product. The results respect all the true parameters from the density of the used materials to the final shadows that will appear. You have an empty place and you want to see how it is going to look like after building something there. So you get to virtually build it and find out which could be the main drawbacks in order to avoid great financial losses.
