This document outlines the course details for an Engineering Visualization course. The course aims to teach students the basic principles of engineering drawing, how to use drawing as a communication tool, and how to generate pictorial views using CAD software. It is a 3 credit course that involves both continuous internal evaluation and semester end exams. The course is divided into 5 modules that cover topics like orthographic projections, isometric projections, development of surfaces, and multidisciplinary applications. Students will learn drawing, develop visualization skills, and be able to represent engineering components graphically. Assessment includes tests, evaluations of drawing works, and exams with questions from each module.

CLO3: To generate pictorial views using CAD software. As Per the VTU Syllabus Dr. Mohammed Imran CLO3: To generate pictorial views using CAD software. CLO4: To understand the development of surfaces. CLO5: To visualise engineering components
- 3. TEACHING-LEARNING (GENERAL INSTRUCTIONS): Students should be made aware of powerful engineering communication tool – Drawing. Simple Case studies can be suitably selected by the teacher for hands on practice to induce the feel of fruitfulness of learning. Appropriate Models, Power Point presentation, Charts, Videos, shall be used to enhance visualization before hands on practice. For application problems use very generally available actual objects. As Per the VTU Syllabus Dr. Mohammed Imran For application problems use very generally available actual objects. (Example: For rectangular prism / object; matchbox, carton boxes, book, etc can be used. Similarly for other shapes) Use any CAD software for generating orthographic and pictorial views. Make use of sketch book with graph sheets for manual / preparatory sketching

- 10. Assessment Details (both CIE and SEE) The weightage of Continuous Internal Evaluation (CIE) is 50% and for Semester End Exam (SEE) is 50%. The minimum passing mark for the CIE is 40% of the maximum marks (20 marks) and that for SEE minimum passing mark is 35% marks (20 marks) and that for SEE minimum passing mark is 35% of the maximum marks (18 marks). A student shall be deemed to have satisfied the academic requirements and earned the credits allotted to each subject/ course if the student secures not less than 35% ( 18 Marks out of 50)in the semester-end examination(SEE), and a minimum of 40% (40 marks out of 100) in the sum total of the CIE (Continuous Internal Evaluation) and SEE (Semester End Examination) taken together Dr. Mohammed Imran
- 11. Continuous Internal Evaluation (CIE) CIE shall be evaluated for max marks 100. Marks obtained shall be accounted for CIE final marks, reducing it by 50%. CIE component should comprise of Continuous evaluation of Drawing work of students as and when the Modules are covered on the basis of work of students as and when the Modules are covered on the basis of below detailed weightage. At least one closed book Test covering all the modules on the basis of below detailed weightage. Weightage for Test and Continuous evaluation shall be suitably decided by respective course coordinators. Dr. Mohammed Imran
- 12. Continuous Internal Evaluation (CIE) Dr. Mohammed Imran
- 13. Semester End Examination (SEE) SEE shall be conducted and evaluated for maximum marks 100. Marks obtained shall be accounted for SEE final marks, reducing it by 50% Question paper shall be set jointly by both Internal and External Examiner and made available for each batch as per schedule. Questions are to be set preferably from Text Books. Evaluation shall be carried jointly by both the examiners. Scheme of Evaluation: To be defined by the examiners jointly and the same shall be submitted to the university along with question paper. One full question shall be set from each of the Module from Modules 1,2,3,4 as per the below tabled weightage details. However, the student may be awarded full marks, if he/she completes solution on computer display without sketch. Dr. Mohammed Imran
