Graphics communication using engineering drawings and models is a language, a clear, precise language with definite rules that must be mastered if you are to be successful in engineering design. Once you know the language of graphics communications, it will influence the way you think, the way you approach problems. Why? Because humans tend to think using the languages they know. Thinking in the language of engineering graphics, you will visualize problems more clearly and will use graphic images to find solutions with greater ease.
