1 Department Course Code Course Title Course Category : MECHANICAL ENGINEERING : A10301 : ENGINEERING DRAWING : Core Course Structure : Lectures Tutorials Practical s Credits 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. Each midterm examination consists of one subjective paper for 15 marks with duration of 1 hour 30 minutes. Subjective paper contains of 4 full questions of which, the student has to answer 2 questions, each question carrying 7.5 marks. Drawing charts and assignment charts will be evaluated for 10 marks. First midterm examination shall be conducted for 1 st unit of syllabus and second midterm examination shall be conducted for 2-3 units. Assignments should be submitted before the conduct of the mid examinations. The total marks secured by the student in each midterm examination are evaluated for 25 marks, and the average of the three midterm examinations shall be taken as the final marks secured by each candidate. University End Exam Marks Total Marks IV. Evaluation Scheme: S.
