Course Objectives
The objective of this course is:
- To enhance the students knowledge and skills in engineering drawing
- To introduce computer aided drafting packages and commands for modeling and sketching.
- To learn surface modeling techniques required designing and machining
- To draw the geometric entities and create 2D and 3D wire frame models.
- To learn various modelling techniques such as edit, zoom, cross hatching, pattern filling,rotation, etc.
Course outcomes
Up on completion of the course, the student shall be able to :
- Understand the paper –space environment thoroughly
- Develop the components using 2D and 3D wire frame models through various editing commands.
- Generate assembly of various components of compound solids.
UNIT-I : Objective: The knowledge of projections of solids is essential in 3D modelling and animation. The student will be able to draw projections of solids. The objective is to enhance the skills they already acquired in their earlier course in drawing of projection and sections of solids. Projections Of Planes & Solids : Projections of Regular Solids inclined to both planes – Auxiliary Views. Sections and Sectional views of Right Regular Solids – Prism, Cylinder, Pyramid, Cone – Auxiliary views.
UNIT-II : Objective: The knowledge of development of surfaces of solids is required in designing and manufacturing of the objects. Whenever two or more solids combine, a definite curve is seen at their intersection. The intersection of solids also plays an important role in designing and manufacturing. The objective is to impart this knowledge through this topic. Development And Interpenetration Of Solids: Development of Surfaces of Right Regular Solids – Prisms, Cylinder, Pyramid Cone and their parts. Interpenetration of Right Regular Solids – Intersection of Cylinder Vs Cylinder, Cylinder Vs Prism, Cylinder Vs Cone.
UNIT-III : Objective: Isometric projections provide a pictorial view with a real appearance. Perspective views provides a realistic 3D View of an object. The objective is to make the students learn the methods of Iso and Perspective views. Isometric Projections : Principles of Isometric Projection – Isometric Scale – Isometric Views – Conventions – Isometric Views of Lines, Plane Figures, Simple and Compound Solids – IsometricProjection of objects having non- isometric lines. Isometric Projection of Spherical Parts. Transformation of Projections: Conversion of Isometric Views to Orthographic Views – Conventions. Perspective Projections: Perspective View: Points, Lines, Plane Figures and Simple Solids,Vanishing Point Methods(General Method only).
PART- B COMPUTER AIDED DRAFTING
UNIT- IV : Introduction To Computer Aided Drafting: Generation of points, lines, curves, polygons, dimensioning. Types of modelling: object selection commands – edit, zoom, cross hatching, pattern filling, utility commands, 2D wire frame modelling, 3D wire frame modelling.
UNIT -V : Objective: By going through this topic the student will be able to understand the paper-space environment thoroughly. View Points And View Ports: view point coordinates and view(s) displayed, examples to exercise different options like save, restore, delete, joint, single option.
UNIT -VI : Computer Aided Solid Modelling: Isometric projections, orthographic projections of isometric projections, Modelling of simple solids, Modelling of Machines & Machine Parts.

- Internal Evaluation: Max. Marks: 30
The total internal evaluation marks are distributed in following two components: - Day-to-day work : 20 marks
- Internal test: 10 marks
I Mid (Internal Test 1) Examination Part A – Conventional drawing Exam
II Mid (Internal Test 2) Examination Part B – In Computer Lab
(Note: The duration of the internal test is 2 hours and it must be conducted as per the schedules notified. The internal test may be conducted for 40 marks and it may be reduced to 10 marks).
End Semester Examination (Total Duration: 4 Hours, Max. Marks: 70)
- PART A – Conventional drawing pattern (Duration: 2 Hours, Marks: 35)
- PART B – Computer lab pattern using any drafting packages (Duration: 2 Hours, Marks: 35)
(Note: both PART A and PART B are compulsory and are to be conducted in
separate sessions) Since the pattern of the internal and external examination is not specified in the R13 academic regulation, it is requested that the above pattern may be approved.
