Scheme of Evaluation for Internal Assessment
(40 Marks)
- Class work (Sketching and Computer Aided Machine drawing printouts in A4/A3 size sheets): 20Marks.
- Internal Assessment test in the same pattern as that of the main examination: 20 marks.
Scheme of Examination:
Two questions to be set from each Part.A, part.B and Part.C.
Student has to answer one question each from Part.A, Part.B for 15 marks each and one question from Part.C for 50 marks.
Part.A 1 x 25 = 25 Marks
Part.B 1 x 25 = 25 Marks
Part.C 1 x 50 = 50 Marks
Total = 100 Marks
INSTRUCTION FOR COMPUTER AIDED MACHINE DRAWING (15ME36A/46A) EXAMINATION
- No restriction of timing for sketching/computerization of solutions. The total duration is 3 hours.
- It is desirable to do sketching of all the solutions before computerization.
- Drawing instruments may be used for sketching.
- For Part.A and Part.B, 2D drafting environment should be used.
- For Part.C 3D part environment should be used for parts assembly drawing and extract 2D views.
