In today's world, many students in universities do not learn manual drafting techniques because they are not required to do so. The days of hand drawing for final drawings are virtually over. Universities no longer require the use of protractors and compasses to create drawings, instead there are several classes that focus on the use of CAD software. 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. The accuracy, flexibility and ease of access provided by CAD technology has completely revolutionised every industry it is incorporated into and is now used to model, design and communicate any physical system to the point where it is universally understandable, linking the many stages of industrial process, from the experts and specialists to the blue collars. Over the last couple of decades this has resulted in a significant shift in employment areas away from the middlemen to the two working ends of the process, resulting in increased productivity and efficiency in many fields in society. Chemical Knowledge: Chlorofluorocarbons Growth of the hole in the Ozone Layer Growth of the hole in the Ozone Layer In the 1930s chlorofluorocarbons (CFCs) became an industrial staple due to their
