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
  3. 3(line conventions); IS 11669 (preparation of general engineering drawings); ISO 128 series.). Familiarisation with the CAD interface: coordinate entry, units, limits, object snap, layers, linetypes and file management. Students set up a standard A3/A4 template with a title block that will be reused throughout the semester.
  4. 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: parabolic reflector profile of a dish antenna, and the exponential/tapered profiles used in horn antennas and waveguide transitions.
  5. 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.
  6. 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.
  7. 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.
  8. 6Development of lateral surfaces Parallel line and radial line development of cube, prism, cylinder, cone and truncated solids. Stream context: development of a sheet metal instrument enclosure, a shielding can and a rectangular to circular waveguide transition.
  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 circuit schematic drawing
  11. 4Standard graphical symbols for passive components, semiconductor devices, sources, connectors and instruments as per IEEE Std 315 / IEC 60617 / IS 2032. Preparation of a neat schematic of a small circuit (regulated d.c. power supply or an op amp signal conditioning stage) with reference designators, net labels and a component list; block diagram of the same system for comparison.
  12. 9Printed circuit board layout from schematic Footprint assignment, board outline, component placement, track width and clearance selection with reference to IPC 2221 and IPC 7351, ground pour, single - and double-sided routing, silkscreen and assembly drawing; generation of Gerber and drill files. Students see explicitly how the same circuit gives rise to two different documents the schematic and the layout.
  13. 103D modelling of an electronic enclosure Solid model of a box type enclosure or a heat sink using extrude/shell/pattern features; cut outs for connectors, display and mounting bosses checked against the board of Experiment 9; automatic generation of the fabrication drawing with dimensions and tolerances.
  14. 11Panel/rack layout, sheet composition and plotting Front panel and 19-inch rack layout drawing with cut outs and legends; cable/harness and interconnection diagram; composition of a complete sheet with title block, plotting to scale, and export to PDF, DXF and Gerber for fabrication.
  15. 12Mini project with an introduction to AI assisted EDA In groups of two or three, students produce the complete documentation set for a small electronic system (for example an IoT sensor node): block diagram, schematic, PCB layout, Gerber output, enclosure model and fabrication drawing. The session includes a demonstration of auto placement/auto routing, design rule checking, AI assisted schematic to layout tools and 3D board–enclosure co design. Evaluation by presentation and viva voce.
  16. 6Internal assessment, viva voce and end semester practical examination
  17. 3Total
  18. 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 Electronics Engineering Stream (ECE) 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 Electronics Engineering Stream (ECE), rather than generic examples.
  • To introduce schematic capture and printed circuit board layout as the drawing language of electronics, and to relate the board to the mechanical enclosure that houses it.
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
  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 circuit schematics, PCB layouts and enclosure drawings using standard symbols. 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.
