- analyze visual messages to determine the appropriateness of their design elements to the effectiveness of the message.
- apply communication design elements and principles to 3 dimensional graphic products.
Introduction
Drawing is a common form of visual communication. It is one of the easiest and fastest ways to exchange ideas and communicate information. One of the major purposes of technical graphics is to describe three dimensional objects in two dimensions. This means showing all the surfaces of the object on a flat piece of paper or a computer monitor. Technical graphics can be divided into two categories technical drawings and technical illustrations.
Technical drawing communicates true size and shape of an object and is therefore a scale representation of a unit or part. The views shown would be those which are required for an accurate description of this part.
Technical illustrations are designed to show a particular aspect of an article or object as clearly as possible or to create an impression. In technical illustration only those details of the object are depicted which are meaningful for the illustration. Insignificant details are omitted. What is meaningful for the illustration depends on the purpose of the communication and the intended audience.
This Section examines technical drawings and technical illustration tools and techniques. Printed material ranging from magazines to advertising, from textbooks to cereal boxes are a direct result of and production and employ aspects of technical drawing and illustration. Good can render information so that it is more easily understood. Technical drawing and illustration should be developed in context as a component of other productions.
