All phases of manufacturing or construction require the conversion of new ideas and design concepts into the basic line language of graphics. Therefore, there are many areas (civil, mechanical, electrical, architectural and industrial) in which the skills of drafting play major roles in the design and development of new products or construction. Engineering Graphics is the language of architects and engineers. Just like any other language, we need to learn the vocabulary and grammar in order to be able to communicate. Engineering graphics course is the course which imparts vocabulary and grammar for the language of architects and engineers. Engineering graphics has two distinct components – 2D and 3D. In this course we will cover the topics related to 2D in graphics.This course is designed to address: • to enable you to communicate in engineering/architectural language of drawings • to prepare you to use the techniques, skills, and modern engineering tools necessary for engineering practice The student will learn : • Introduction to engineering design and its place in society • Exposure to the visual aspects of engineering design • Exposure to engineering graphics standards • Exposure to engineering communication INTENDED AUDIENCE :Bachelor of Engineering in any discipline Bachelor of ArchitecturePREREQUISITES : NoneINDUSTRIES SUPPORT :Not applicable
