People that know Cad, (Computer Aided Drafting) are a different breed of people. These people see the world in an entirely different way then others do. They know how to take advantage of how the world is organized. Nearly every system or process in the world is at their mercy. Specifically systems of measurement are easy for them to understand and manipulate. Cad is easy to learn and rewards the time invested in becoming good at it. The better you become at it the more you learn to accomplish with it. Cad has become much more than just a drawing program. Cad can help you create an image, manage a whole city or design a motion picture. You could map out the discovered universe or demonstrate how the human body works
Cad uses information produced by other types of programs like word processing or spreadsheets, databases and alerting systems. So people who learn to speak (use) Cad, by osmosis start to see how the world around them works. The rules and standards used in many industries are incorporated into the Cad interface and make them easier to grasp and navigate through. There are automated functions that do what would ordinarily take days, in a matter of minutes. Cad is weaving its way into every nook and cranny of society and is used in almost every country in the world. The sooner you learn to speak Cad the better, so when everyone else discovers what you already know.
Cad is a language that gives its speaker great power.
