Note: There will be one Question Paper which will have 50 questions out of which 40 questions need to be attempted. |
Unit 1:
Construction of isometric scale showing main divisions of 10mm and smaller divisions of 1mm, also showing the leading angles. Isometric projection (drawn to isometric scale) of solids such as cube; regular prisms and pyramids (triangular, square, pentagonal and hexagonal); cone; cylinder; sphere; hemisphere; keeping the base side of the solid parallel or perpendicular to HP/VP. The axis of the solid should be either perpendicular to HP / VP or parallel to HP and VP.
ISOMETRIC PROJECTION OF SOLIDS
Unit 2:
Combination of any two above-mentioned solids keeping the base side parallel or perpendicular to HP/VP and placed centrally together (Axis of both the solids should not be given parallel to HP).
Machine Drawing (Machine Parts)
Unit 3:
Drawing to full size scale with instruments. Introduction of threads: Standard profiles of screw threads - Square, Knuckle, B.S.W., Metric (external and internal); Bolts – Square head, Hexagonal head; Nuts – Square head, Hexagonal head; Plain washer; combination of nut and bolt with or without washer for assembling two parts together.
Machine Drawing (Machine Parts)
Unit 4: Free-hand sketches

Tips For Engineering Graphics
-
Practice drawing of engineering objects in 1st/3rd angle, inclusive of cross-sectional drawings, plane and elevation.
-
Familiarize yourself with drawing standards, symbols and software.
-
Keep visualizing things and different views for those things.
-
Make flashcards to remember the definitions of the new terms you come across, and be thorough with the theoretical part.
How to score well
-
Before you start the exam, utilize the first 15 minutes to scan the paper. Read the question paper thoroughly before jumping to write the answers.
-
Among the questions with internal choices, select the ones that you plan to attempt, and frame skeletons of the answers you are going to write for these questions.
-
Follow a pattern. For example, in case you start with long answer questions, complete that section and only then move to short or very short answer section.
-
Highlight the important points and write your answer in points to enhance visibility.
