Technical Drawing (Grade 8) by Mr. Obinna Nwogbaga
RATIONALE
Technical Drawing is a visual means of communicating clearly and concisely all the information (drawings, dimensions, notes, specifications) necessary to transfer an idea or concept into reality. It is based on the principles of projection in two-dimensional and three-dimensional representations. Technical Drawing has its most common application in the field of manufacturing, engineering, architecture and construction where it is used to document and support the design process. This is accomplished by communicating ideas about the shape, form, dimensions, materials, manufacturing methods and finishes of articles to be produced. Technical Drawing plays an indispensable role in determining the quality and competitiveness of finished products in the design process. It is, therefore, an important prerequisite and an essential companion for the CSEC Industrial Technology programmes which provide the foundational competencies in manufacturing and industrialisation in the Caribbean.
