Subject Description

Presentation 2011 Website Version

Graphical Communication is an international graphic language. Drawings or symbols are able to convey meaning in spite of language barriers. Every manufactured object we see around us, be it a car, a mobile phone, a house, a machine or an engineering component undergoes a process of design and production. The item is first sketched free hand and then presented pictorially to the client. Once approved, the working drawing, or better still the orthographic views are produced so that the item can be sent for production. Geometric shapes, both plane and solid, are commonly used in preparing the working drawings.

Through Graphical Communication, students develop their ability to impart data by means of drawings and diagrams, a skill widely recognized in today’s technological world. Students will be able to acquire the necessary skills to generate freehand drawings, pictorial views and orthographic projections. Topics regarding plane and solid geometry are also covered. Students will also learn how to design symbols and signs which serve as essential communication tools. These self-explanatory symbols are widely used when information and/or instructions need to be conveyed, such as information signs used in roads, airports, bus/train stations, construction sites, cargo handling, packaging, electrical /electronic circuits and so on.

At the end of the course, students may sit for the SEC examination, after which they can opt to follow up this subject at intermediate and advanced level.
