Engineering Drawing, also known as Engineering Drafting and a type of technical drawing, is used to fully and clearly define requirements for engineered items. More than just the drawing of pictures, it is also a language, a graphical language that communicates ideas and information from one mind to another. Most especially, it communicates all needed information from the engineer who designed a part to the workers who will make it.

About the Course

One of the best ways to communicate one's ideas is through some form of picture or drawing. This is especially true for an engineer. The purpose of this guide is to give you the basics of engineering sketching and drawing. We will treat "sketching" and "drawing" as one. "Sketching" generally means freehand drawing. "Drawing" usually means using drawing instruments, from compasses to computers to bring precision to the drawings.

Course Syllabus:

Introduction to CAD

Advantages of using Computer Aided Drafting (CAD) packages, applications of CAD, basic operation of drafting packages, use of various commands for drawing, dimensioning, editing, modifying, saving and printing/plotting the drawings.

Sections of Solids

Types of section planes, types of sectional views i. e. sectional FV , sectional TV, sectional SV, to project sectional views of above solids cut by different section planes (when solid is in simple position , when axis is parallel to one & inclined to other reference planes ), to find true shape of sections.

Development of Lateral Surfaces (DLS) of Solids

Applications of DLS, method of development, development of lateral surface of above solids, development of lateral surface of cut solids.

Interpretation of Given Views/Missing Views

Identification of lines/edges and surfaces, visualization of given orthographic views, adding a missing/third view.

Recommended Background

You should have a background of visualizing the object.
