Intro to Engineering Graphics
QUESTION 1
Drawing is a graphical representation of a thought, an idea, a concept, a structure or an object which actually or potentially exists in life and could be done using freehand, mechanical or computer methods. It can also be defined as a graphical language in engineering application that use lines to represent the surfaces, edges and contours of objects. It can also be referred to as drafting.
The drawing itself is
• A way of communicating all necessary information about abstraction ,such as an idea or a concept
• A graphic representation of some real entity, such as machine part, a house, a tool.
Types of drawing includes
Artistic drawing
Technical drawing
Rendering or illustration drawing
ARTISTIC DRAWING: it ranges in scope from the simplest line drawing to the most famous paintings. Regardless of their status or complexity, they are used to express the feelings, beliefs, philosophies or abstract ideas of the artist. Hence in order to understand it, you must understand the artist.
TECHNICAL DRAWING: it is a means of clearly and concisely communicating all of the information necessary to transform an idea or a concept to reality. It can also be defined as an act or discipline of composing plans that virtually communicate how something functions or how it is to be constructed. Therefore, a technical drawing often contains more than a graphical representation of its subject. It also contains dimensions notes and specification.
RENDERING OR ILLUSTRATIONS: they are neither completely technical nor artistic, they combine elements from both hence are referred to as the third type of drawing. They are technical in that they are drawn with mechanical instrument or on a computer-aided drafting system and they contain some degree of technical information. However, they are also artistic in that they attempt to convey a mood, a status, or other abstract, non technical feelings.
Projection is a protocol by which an image of a three-dimensional
