Department Course Code Course Title Course Category : MECHANICAL ENGINEERING : A10301 : ENGINEERING DRAWING : Core Course Structure : Lectures Tutorials Practical s Credits 2-4 6 I. Course Overview: One of the best ways to communicate one's ideas is through some form of picture or drawing. This is especially true for the engineer. An engineering drawing course focuses on usage of drawing instruments, lettering, construction of geometric shapes, etc. Students study use of dimensioning, shapes and angles or views of such drawings. Dimensions feature prominently, with focus on interpretation, importance and accurate reflection of dimensions in an engineering drawing. Other areas of study in this course may include projected views, pictorial projections and development of surfaces. This course also gives basic concepts for studying machine drawing, building drawing, circuit drawings etc. II. Prerequisite(s): III. Marks Distribution: Sessional Marks (25) Mid Semester Test: There shall be 3 midterm examinations.
