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
  3. 3engineering 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.
  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: involute of a circle (gear tooth profile), cycloid (cam and rolling contact) and helix (screw thread and spring).
  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 transition piece, a funnel and an elbow, of the kind fabricated in a sheet metal shop.
  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. 8Machine component drawing with tolerancing conventions Orthographic and sectional views of a machine component (bearing bracket, stuffing box or a simple housing).
  11. 4Conventional representation of external and internal screw threads, fasteners, keys, splines and springs. Indication of limits and fits as per IS 919, geometrical tolerances as per ISO 1101, and surface texture symbols as per IS 10719, with a short discussion on why a shop drawing is incomplete without them.
  12. 9Assembly drawing from part drawings Given the detail drawings, students prepare the assembly drawing of a knuckle joint, cotter joint, flanged coupling or screw jack with sectional front view, item balloons, a parts list/bill of materials and only the overall, fit and installation dimensions. One reverse exercise: given an assembly, extract the detail drawing of one part.
  13. 103D solid modelling and drawing derivation Feature based modelling of a component (V belt pulley, flange, connecting rod or a bracket) using extrude, revolve, sweep, fillet, chamfer, hole and pattern features; a simple two-part assembly with mates; automatic generation of the orthographic and sectional drawing views with a bill of materials from the model.
  14. 11Sheet composition, plotting and CAD data exchange Composition of a complete drawing sheet with title block, revision table and multiple scaled views; plotting to scale; export to PDF and DXF for a laser/waterjet job and to STL/STEP for 3D printing and for exchange with a different CAD package. Discussion of why STEP is preferred over native formats for archival.
  15. 12Mini project with an introduction to parametric and AI assisted design In groups of two or three, students prepare a complete drawing set (detail drawings plus an assembly drawing with BOM) of a small mechanism or sub assembly, together with its 3D model. The session includes a demonstration of design tables/parametric configurations, topology optimisation and generative design, and of the CAD–CAM chain up to tool path or slicer output. 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 Mechanical Engineering Stream (ME) 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 Mechanical Engineering Stream (ME), rather than generic examples.
  • To introduce limits, fits, tolerances and surface texture symbols, and to expose students to solid modelling and its downstream use in CAM and additive manufacturing.
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 detail and assembly drawings of machine components with sectioning, tolerancing and surface-texture indications.. 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.
