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.
  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: cam profiles of a tappet shedding mechanism, the helix of yarn twist on a package, and the cycloidal traverse of a builder motion.
  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 cone/cheese package surface, a conical funnel of a fibre transport duct and a sheet metal machine guard.
  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 textile machine component Orthographic and sectional drawing of a machine part, a ring frame spindle with bolster and wharve, a heald and reed section, a shuttle, a tappet/cam profile or a drafting roller with its bearing. The cam profile is plotted from the
  11. 4displacement diagram rather than copied, so that the link between motion requirement and geometry is visible.
  12. 9Weave design: point paper design, draft and peg plan Preparation of point paper (design paper) representations of plain, twill, satin/sateen and a simple derivative weave, together with the corresponding drafting plan and peg/lifting plan, drawn on a CAD grid using ARRAY and layer control; cross sectional views of the fabric structure along warp and weft. A colour and weave effect is produced for one design.
  13. 103D modelling of a textile component Solid model of a component such as a bobbin, cone, cot/apron roller or a package holder arm, using revolve/extrude/sweep features; automatic generation of orthographic and sectional views from the model.
  14. 11Garment pattern block, mill layout, sheet composition and plotting Drafting of a basic bodice/sleeve block to given measurements with grain lines, notches and seam allowances; and a machine layout plan of a spinning or weaving shed showing machine positions, passages, material flow and clearances. Composition of a complete sheet with title block; plotting to scale and export to PDF/DXF.
  15. 12Mini project with an introduction to textile CAD/CAM and AI tools In groups of two or three, students deliver either a machine component drawing set (detail plus assembly, with 3D model) or a design set (weave/print design with fabric cross sections and a pattern block). The session includes a demonstration of jacquard/dobby design software, digital printing workflows, 3D garment simulation, and AI assisted print/weave design generation and defect detection. 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 Textile Engineering Stream (TX) 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 Textile Engineering Stream (TX), rather than generic examples.
  • To develop the ability to prepare drawings of textile machine components, fabric design diagrams and mill layouts, and to introduce textile specific CAD as used in the industry.
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 textile machine components, weave-design diagrams and mill layouts. 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.
