Engineering Graphics Syllabus for Class XI

  1. PLANE GEOMETRY

Printing English alphabets (capital and small) numerals in standard proportions. Unidirectional/aligned system of dimensioning as per

Unit – 1: Construction of lines, angles and their divisions. Simple questions based on triangles, square, rhombus, trapeziums, regular polygons-pentagon, hexagon, and octagon. Unit – 2: Construction of circles, external and internal tangents of circles, inscribing, circumscribing circles in an equilateral triangle, square, rhombus, regular polygons-pentagon, hexagon, and octagon.

Unit – 3: Construction of Engineering curves:

  • Ellipse by concentric circles, intersecting arcs, and intersecting lines.
  • Parabola by intersecting lines and intersecting arcs.
  • Involute of a circle, cycloid, helix and sine curve.

2. SOLID GEOMETRY

Unit – 4: Methods of orthographic projections and dimensioning strictly as per SP: 46- 2003 revised conventions. Projection of points, lines.

Unit – 5 : Orthographic projections of Regular Plane figures – triangle, square, pentagon, hexagon, circle and semi-circle.

Unit – 6: Orthographic projections of right regular solids such as cubes, prisms, and pyramid, (square, triangular, pentagonal and hexagonal), cones, cylinders, spheres, hemispheres and frustum of pyramids and cone when they are kept with their axis

(a) Perpendicular, to HP/VP

(b) Parallel to one plane and inclined to the other

(c) Parallel to HP and VP both.

Unit – 7: Section of solids under the same conditions mentioned above made by the horizontal, vertical and inclined planes.

III. MACHINE DRAWING

Unit – 6: Orthographic projections of simple machine blocks.

Unit – 7: Construction of isometric scale showing main divisions of 10 mm and smaller divisions of 1 mm each. Isometric projection (drawn to isometric scale) of figures such as triangles, squares, pentagons, hexagons, circles and semi-circles with their surface parallel to HP or VP and its one side or diagonal or diameter should be either parallel or perpendicular to HP/VP.
Unit – 8: Development of the surfaces of the following solids :

  • Cube, cuboid, prisms-triangular, square, pentagonal and hexagonal.
  • Pyramids (triangular, square, pentagonal and hexagonal).
  • Right circular cylinder and cone.

Practicals

  • Developing “Prisms” and “Pyramids” with the help of cardboard (thick paper).
  • Making different types of graphic designs/ murals for interior/ exterior decorations in color using the knowledge of geometrical figures with the use of any Computer Software such as Collab-CAD and /or any equivalent pertinent software.
  • Developing different types of packaging boxes (cartons).
  • Preparing top-view (plan) of a classroom, Home: Drawing room / Bedroom / Study room / Kitchen, Engineering Graphics room drawing different objects therein.
  • Drawing ellipse by Trammel and Thread method on the ground/drawing sheet /plywood/cardboard, etc
  • Drawing through activities: Involutes, cycloid, helix and sine curves listing their uses in daily life.
  • Preparing the following sections of solids (prisms, pyramids, 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 and inclined to the base. Also creating different objects with a combination of above solids.

Note :

  • 20 activities (minimum two each from a fore mentioned seven points) are to be assessed.
  • In all the practicals, drawing/sketching of the views should be incorporated and evaluated accordingly.
