TABLE OF CONTENTS Communication involves actions to exchange meanings between individuals through a common system of symbols. This system must possess the basic essentials: common symbols, grammar, and composition. Relying on these essentials, human beings have been able to communicate effectively.
Although the distinction of engineering design communication is that it is conducted between engineers, it has no difference from the general understanding of communication in that it possesses the three essentials mentioned above for effectiveness. However, when engineering designs are communicated, the common symbols are elemental constituents of points, lines, curves, planes, and the spaces created using these constituents. The grammar that governs the placement of these constituents is the science of descriptive geometry. Descriptive geometry establishes the relationships between elemental constituents in terms of their views in different angles of projection. The composition of engineering design presentation is dictated by industrial conventions, general concepts, and standards in the profession. For instance, Figure 1-1 shows a spatial point A(a small ball was used instead for easy visual effect) that we will presentusing the language of engineering design communication.
Because a point in engineering language has no physical size, the most important information of interest is its position in the space. To define the position of Point A, three orthographic views adjacent to each other are used in Figure 1-2.
These three orthographic views are made according to the principles of descriptive...
