Course objectives:Engineering drawing is an important tool for all Engineers and for many others professionals. It is the language of Engineers. Engineering Drawing communicates all needed information from the engineer who designed a part to the workers who will manufacture it. The aim of the subject is to equip students with the fundamentals of Computer Aided Engineering Drawing and to further the ability to communicate information by graphical means.

Module -1:     (06 Hours)
Introduction to Computer Aided Sketching:
Introduction, Drawing Instruments and their uses, BIS conventions, Lettering, Dimensioning and free hand practicing. Computer screen, layout of the software, standard tool bar/menus and description of most commonly used tool bars, navigational tools. Co-ordinate system and reference planes. of HP, VP, RPP & LPP. of 2D/3D environment. Selection of drawing size and scale. Commands and creation of Lines, Co-ordinate points, axes, poly-lines, square, rectangle, polygons, splines, circles, ellipse, text, move, copy, off-set, mirror, rotate, trim, extend, break, chamfer, fillet, curves, constraints viz. tangency, parallelism, inclination and perpendicularity. Dimensioning, line conventions, material conventions and lettering.

Module -2 :     (20 Hours)
Orthographic projections Introduction, Definitions – Planes of projection, reference line and conventions employed, Projections of points in all the four quadrants, Projections of straight lines (located in First quadrant/first angle only), True and apparent lengths, True and apparent inclinations to reference planes (No application problems). Orthographic Projections of Plane Surfaces (First Angle Projection Only) Introduction, Definitions–projections of plane surfaces–triangle, square, rectangle, rhombus, pentagon, hexagon and circle, planes in different positions by change of position method only (No problems on punched plates and composite plates).

Module -3:     (28 Hours)
Projections of Solids (First angle Projection only) Introduction, Definitions – Projections of right regular tetrahedron, hexahedron (cube), prisms, pyramids, cylinders and cones in different positions (No problems on octahedrons and combination solid).

Module -4 :     (15 Hours)
Sections And Development of Lateral Surfaces of Solids Introduction, Section planes, Sections, Section views, Sectional views, Apparent shapes and True shapes of Sections of right regular prisms, pyramids, cylinders and cones resting with base on HP. (No problems on sections of solids) Development of lateral surfaces of above solids, their frustums and truncations. (No problems on lateral surfaces of trays, tetrahedrons, spheres and transition pieces).

Module -5 :     (15 Hours)
Isometric Projection (Using Isometric Scale Only) Introduction, Isometric scale, Isometric projection of simple plane figures, Isometric projection of tetrahedron, hexahedron(cube), right regular prisms, pyramids, cylinders, cones, spheres, cut spheres and combination of solids (Maximum of three solids).

Course outcomes: After studying this course,

• Students will be able to demonstrate the usage of CAD software.
• Students will be able to visualize and draw Orthographic projections, Sections of solids and Isometric views of solids.
• Students are evaluated for their ability in applying various concepts to solve practical problems related to engineering drawing.

Question paper pattern: Scheme of Examination

• Module 1 is only for practice and Internal Assessment and not for Examination.
• Question paper for each batch of students will be sent online by VTU and has to be downloaded before the commencement of Examination of each batch. The answer sheets will have to be jointly evaluated by the Internal and External examiners.
• A maximum of THREE questions will be set as per the following pattern (No mixing of questions from different Modules)
Q. No. From Modules Marks allotted 40
01 Module 2 Exam Marks 30
02 Module 3 Exam Hours 40
03 Module 4 or Module 5 Exam Hours 30
Total 100

Scheme of Evaluation

Q. No. Solutions & Sketching on graph book Marks allotted 40
01 10 Marks 20 Marks 30
02 15 Marks 25 Marks 40
03 15 Marks 15 Marks 30
Total  40 Marks  60 Marks 100
• Students have to submit the computer printouts and the sketches drawn on the graph sheets at the end of the examination. Both Internal and External examiners have to jointly evaluate the solutions (Sketches), Computer display and Printouts of each student for 100 Marks (40 Marks for solutions & sketches + 60 Marks for computer display and printouts). Submit the marks list along with the solution (sketches) on graph sheets and computer printouts in separate covers.
• Each batch must consist of a minimum of 10 students and a maximum of 12 students
• Examination can be conducted in parallel batches, if necessary.
