Engineering Graphics

Students should carefully read the syllabus of Engineering Graphics to get an idea about the type of questions asked in the examination. The detailed syllabus is as follows: 

Theory 

I. Plane Geometry 

Unit 1

• Construction of lines
• Angles and Their Divisions
• Simple questions based on triangles, rhombus, square, regular polygons-pentagon, and hexagon

Unit 2

• Construction of circles
• Regular hexagon
• Inscribing and Circumscribing of Circles in Equilateral Triangle
• Inscribing and Circumscribing of Circles in Square
• Inscribing and Circumscribing of Circles in Rhombus
• Regular Polygons-Pentagon 

II. Solid Geometry  

Unit 4

• Orthographic projection
  • Orthographic projection of points and lines
  • Dimensioning and Conventions strictly as per SP 46:2003 (Revised)

Unit 5

• Orthographic projection of regular plane figures
  • Square
  • Triangle
  • Hexagon
  • Circle And Semi-Circle
  • Pentagon

Unit 6

• Orthographic Projection of Right Regular Solids Such as Cubes
• Prisms and Pyramids (Square, Pentagonal, Triangular, and Hexagonal)
• Cylinders
• Cones
• Hemi-Spheres
• Spheres
• Frustum of Pyramids and Cone
• When they are Kept With their Axis
  • perpendicular to HP/VP
  • parallel to HP and VP both

Unit 7

• Section of Right Regular Solids Such as Cubes
• Cones
• Prisms and Pyramids (Square, Triangular, Pentagonal, and Hexagonal)
• Cylinders
• Spheres kept with their axis perpendicular to HP/VP, made by a vertical cutting plane

III. Machine Drawing 

Unit 8 

• Orthographic projection of simple machine blocks

Unit 9

• Isometric Projection
  • Construction of isometric scale showing main divisions of 10 mm and smaller divisions of 1 mm each. 
• Isometric projection (drawn to isometric scale) of regular plane figures
  • square
  • triangle
  • hexagon
  • circle 
  • pentagon
  • semi-circle with their surface parallel to HP or VP (keeping one side either parallel or perpendicular to HP/VP)

Practicals  

1. Drawing the following engineering curve through activities – ellipse (by trammel & thread method) on the ground/ plywood/ drawing sheet/ cardboard etc.
2. Making different types of murals for interior/ graphic designs/ exterior decorations in colour using the knowledge of geometrical figures with the use of any Computer Software such as Collab-CAD and/or any equivalent pertinent software. 
3. Preparing the section of solids (pyramids, prisms, spheres, etc.) with clay, soap, thermocol, plasticine, wax or any other material (easily and economically available). When the cutting plane is- parallel to the base, perpendicular to the base or inclined to the base.
4. Developing the following solids with the help of cardboard/ thick paper:
   • Prisms & Pyramids (triangular, square, pentagonal and hexagonal)
   • Cuboid, Cube
   • Right circular cylinder and Cone
