Section of Solids:- Section of Prism, Pyramid, Cylinder, Tetrahedron, Hexahedron & Cone cut by plane perpendicular to at least one reference plane.( Exclude Curved Section Plane). Use change of position or Auxiliary plane method

Development of Lateral Surfaces of Sectioned Solids:- Lateral surface development of Prism, Pyramid, Tetrahedron, Hexahedron, Cylinder, Cone with section plane inclined to HP or VP only. (Exclude DLS of a solid with a hole in it and Reverse Development). (Exclude Reverse Development)

Unit 4 (12 hours)

Orthographic and Sectional Orthographic Projections:-
i. Different views of a simple machine part as per the first angle projection method recommended by I.S.
ii. Full or Half Sectional views of the Simple Machine parts.
iii. Drawing of orthographic projections using Auto CAD.

Unit 5 (10 hours)

Isometric Views:- Isometric View/Drawing of blocks of plain and cylindrical surfaces using plain/natural scale only. (Exclude Spherical surfaces).
i. Drawing of Isometric views using Auto CAD.
ii. Reading of Orthographic Projections. [Only for Practical Exam (AutoCAD) and Term Work]

Working in 3-dimensions, Viewing 3D Objects, Basic wireframe models, Extruding, simple revolved objects. Boolean operations.

TERM WORK:
Component – 1
Drawing Sheet – 1: Projection of Solids (3 Problems)
Drawing Sheet – 2: Section of Solids and Development of lateral surfaces (2 Problems)
Drawing Sheet – 3: Orthographic Projection without section (2 Problems)
Drawing Sheet – 4: Orthographic Projection with section (2 Problems)
Drawing Sheet – 5: Isometric Views (3 Problems)

Component -2
One A-3 size sketch book consisting of:-
1) Two problems each from Engineering Curves, Projection of Lines, Planes and Solids. One problem from Section of solids without DLS and one problem from section of solids with DLS of that sectioned Solid.
2) Two problems from Orthographic Projections (with Section), One problem on Reading of Orthographic projections and Two problems on Isometric views.

Component-3
Printouts (preferably on A3 size sheet) of each from:
1. Orthographic Projections with Section – 3 problems.
2. Isometric Views – 4 problems
3. Reading of Orthographic Projections – 1 problem.

Note:- 2 hrs /week Auto CAD Practical is essential for completing the Auto CAD Drawings and take required printouts.

AUTO CAD PRACTICAL EXAMINATION: (2hrs – 50 marks):
1) Minimum 1 problem from 1 OR 3 of Component-3 for 30 marks. (All three views with at least 12 dimensions must be asked in the exam) AND
2) Minimum 1 problem from 2 of Component-3 for 20 marks.

Note:- Print out of the Answers have to be taken preferably in A3 size sheets and should be Assessed by External examiner only. Knowledge of concepts and accuracy of drawing should be considered during evaluation.

INTERNAL ASSESSMENT TEST: (1 hr – 15 marks)
Out of the two tests, one test must be conducted by conventional way and another test must be Practical Exam (using AutoCAD software). Average of the two tests must be considered for Internal Assessment.

END SEMESTER EXAMINATION: (3 hrs – 60 marks)
1) Question paper will comprise of 6 questions, each carrying 15 marks.
2) Any 4 questions need to be solved. There won’t be any compulsory Question.
3) Marks of each topic should be proportional to number of hours assigned to each Module.
