Course outcomes

At the end of the course the student will be able to:

CO 1. Understand and visualize the objects with definite shape and dimensions

CO 2. Analyze the shape and size of objects through different views

CO 3. Develop the lateral surfaces of the object

CO 4. Create a 3D view using CAD software.

CO 5. Identify the interdisciplinary engineering components or systems through its graphical representation.

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% 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

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 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.

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.
