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, linetypes and file management.
  3. 3Students 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: the logarithmic spiral and helical surfaces of a mould board plough bottom, and the parabolic profile of a water jet from a sprinkler nozzle.
  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 grain bin hopper, a cyclone of a thresher/aspirator and a sheet metal chute.
  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. 8Drawing of a farm implement component Orthographic and sectional drawing of an implement part — a mould board plough bottom (share, mould board, landside, frog), a cultivator tine with shovel, a disc harrow gang, or a seed metering plate. Material and heat treatment notes, and the wear surfaces, are called out on the drawing.
  11. 9Implement assembly and farm layout drawing
  12. 4Assembly drawing of the three-point linkage hitch of the implement of Experiment 8, with item balloons and a parts list; and a farm layout drawing showing field boundaries, contours or spot levels, farm roads, a farm pond and a drip/sprinkler irrigation layout with mains, sub mains and laterals.
  13. 103D modelling of an implement or irrigation component Solid model of a component such as a plough share, a sprinkler nozzle, a rotavator blade or a chaff cutter blade using extrude/revolve/sweep features; automatic generation of orthographic and sectional views from the model.
  14. 11Farm structure drawing, sheet composition and plotting Plan, section and elevation of a small farm structure (cattle shed, storage godown or a farm machinery shed) with dimensioning and conventional material representation; composition of a complete sheet with title block; plotting to scale (1:100 / 1:50) and export to PDF/DXF.
  15. 12Mini project with an introduction to precision agriculture and AI tools In groups of two or three, students prepare a complete drawing set for a farm implement (detail plus assembly, with 3D model) or for a farm/irrigation layout. The session includes a demonstration of GNSS/GIS based farm mapping, drone survey and contour generation, sensor placement for precision agriculture, and AI assisted design and crop layout planning. 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 Agricultural Engineering Stream (AG) 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 Agricultural Engineering Stream (AG), rather than generic examples.
  • To develop the ability to prepare drawings of farm implements, farm structures and irrigation layouts, which are the working documents of an agricultural engineer.

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.
