List of Experiments / Activities

  1. No. Title and Brief Description Hours
  2. 1Drawing standards, sheet layout and the CAD environment Sheet sizes, borders, title block, lines, lettering and dimensioning as per BIS conventions (SP 46 : 2003 (BIS) Engineering Drawing Practice for Schools and Colleges; IS 10711 (sheet sizes and layout); IS 9609 (lettering); IS 10714 (line conventions); IS 11669 (preparation of general engineering drawings); ISO 128 series.). Familiarisation with the CAD interface: coordinate entry, units, limits, object snap, layers, line types and file management. Students set up a standard A3/A4 template with a title block that will be reused throughout the semester.
  3. 2Geometric constructions and engineering curves Construction of polygons, tangents, plain and diagonal scales; conic sections (ellipse, parabola, hyperbola) and one roulette (cycloid or involute) using CAD draw and modify commands (LINE, ARC, OFFSET, TRIM, ARRAY, MIRROR). Stream context: sinusoid and its phasor construction, the involute profile used in commutator/insulation layouts, and catenary/parabolic profiles of overhead line sag.
  4. 3Orthographic projection of points and straight lines Projections of points in the four quadrants; projections of lines inclined to one and both reference planes; true length and true inclination by rotation/trapezoidal method. Principal planes handled on separate CAD layers.
  5. 4Orthographic projection of planes and simple solids First angle projection of planes and of prisms, pyramids, cylinders and cones resting in given positions; front, top and side views. Third angle convention introduced for comparison, since it is common in imported drawings.
  6. 5Sections of solids and true shape of section Solids cut by section planes perpendicular to one reference plane and inclined to the other; sectional views, cutting plane line, hatching conventions and true shape of the section obtained by auxiliary projection.
  7. 6Development of lateral surfaces
  8. 3Parallel line and radial line development of cube, prism, cylinder, cone and truncated solids. Stream context: development of a sheet metal panel enclosure, a cable trunking bend and a transformer tank of a distribution unit.
  9. 7Isometric projection and reading of orthographic views Isometric scale, isometric axes and isometric drawing aids in CAD; conversion of given orthographic views into an isometric view, and the reverse exercise of reading a pictorial view and producing orthographic views. Missing line and missing view problems for visualisation practice.
  10. 8Graphical symbols and single line diagram Standard graphical symbols for machines, transformers, switchgear, protection and measuring devices as per IS 2032 / IEC 60617. Preparation of the single line diagram of a small distribution system incoming supply, transformer, main switchboard, sub circuits and protection with ratings and device designations marked.
  11. 9Wiring layout and earthing layout of a building Internal wiring layout of a small residence or a laboratory drawn over the building plan points, switchboards, circuits, conduit runs and the distribution board schedule with reference to IS 732; earthing layout with electrode, earth conductor and equipotential bonding as per IS 3043. A short cable/conduit schedule is prepared from the drawing.
  12. 103D modelling of an electrical component Solid model of a component such as a transformer core lamination stack, a stator slot section, a bus bar joint or an insulator; generation of its orthographic and sectional views from the model, with clearance and creepage distances dimensioned.
  13. 11Panel general arrangement drawing, sheet composition and plotting General arrangement and front view drawing of a switchboard/panel with equipment placement and legend; composition of a complete sheet with title block and multiple scaled views; plotting to scale and export to PDF/DXF for contractor use.
  14. 12Mini project with an introduction to digital and AI assisted electrical design
  15. 6In groups of two or three, students prepare the complete electrical drawing set of a small building or laboratory single line diagram, wiring layout, earthing layout, panel GA and load schedule including a rooftop solar PV connection on the single line diagram. The session includes a demonstration of intelligent electrical CAD (automatic wire numbering, report and BOM generation), electrical BIM coordination and AI assisted load estimation. Evaluation by presentation and viva voce. Internal assessment, viva voce and end semester practical examination
  16. 3Total
  17. 45Teaching–Learning Methodology Each weekly session begins with a short tutorial (1 hour) on the drawing principle or standard involved, followed by two hours of hands-on CAD work at the terminal. Experiments 1 to 7 build the common graphics foundation. Experiments 8 to 12 are specific to the Electrical Engineering Stream (EE) and are conducted by, or in consultation with, the parent department. Every student maintains a CAD drawing portfolio (soft copy plus a plotted file) which is submitted for internal assessment. Sheets are checked for correctness of projection and for conformity to standards a geometrically correct but non-conforming drawing is returned for correction. The mini project of Experiment 12 is done in groups of two or three and is defended individually in a viva voce.
Course Objectives5 points
  • To familiarise the student with the principles, conventions and standards of engineering drawing, so that a drawing can be read and prepared without ambiguity.
  • To develop the ability to visualise a three-dimensional object and to represent it through orthographic, sectional and pictorial views.
  • To develop working competence in a CAD package for two-dimensional drafting and for basic three-dimensional modelling.
  • To develop the ability to prepare drawings of the components, systems and layouts that occur in the Electrical Engineering Stream (EE), rather than generic examples.
  • To develop the ability to read and prepare single line diagrams, wiring layouts and earthing drawings as per the relevant Indian Standards, which are the working documents of an electrical engineer.
Course Outcomes (COs)5 outcomes

After completion of the course student will be able to:

  1. CO1Apply engineering drawing standards and conventions (BIS/ISO) while setting up and dimensioning a drawing. 3 CO
  2. CO2Construct orthographic and sectional views of points, lines, planes and solids using a CAD package. 3
  3. CO3Develop surfaces and isometric views of solids, read given views to visualise the object, and apply this to draw single-line diagrams, wiring, earthing and panel layouts as per the relevant IS codes. 3
  4. CO4Create three-dimensional models in CAD, derive two-dimensional views from them, and exchange drawing data in standard formats. 3
  5. CO5Compose, plot and defend a complete stream specific drawing set through a mini project, using contemporary CAD practice and emerging parametric/AI assisted tools. 6

Course Context: This is a Project-Based Learning (PBL) course aligned with the AICTE model curriculum on Design Thinking & Innovation. Students work in teams through the complete Design Thinking cycle — Empathize, Define, Ideate, Prototype, Test — to solve a real-world problem. The emphasis is on doing, not lecturing: every session is a workshop or studio activity. The course builds creativity, teamwork, problem-solving, and an entrepreneurial mindset in first-year students of all branches.
