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 torispherical dished end of a bioreactor vessel, the helix of a coil/spiral membrane module, and the parabolic profile of a vortex in an unbaffled vessel.
  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 conical vessel bottom, a cyclone/separator body and a sheet metal instrument housing.
  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 bioprocess equipment component Orthographic and sectional drawing of a stirred tank bioreactor: vessel with dished ends, jacket, baffles, Rushton turbine impeller with shaft and seal, sparger and nozzles. Key ratios (H/D, Dᵢ/D, baffle width) are marked so
  11. 4that the drawing carries process meaning and not merely geometry.
  12. 9Process/utility flow diagram and cleanroom laboratory layout Flow diagram of a simple upstream–downstream sequence (media preparation, sterilisation, fermentation, centrifugation/filtration, chromatography) with equipment symbols and stream labels; and a layout drawing of a laboratory or a small cleanroom suite showing airlocks, material and personnel flow paths, and pressure cascade, with a note on why the flows must not cross.
  13. 103D modelling of a bio component or a biomedical device
  14. part Solid model of an impeller, a filter housing, or for the biomedical branch a simple device component such as a prosthetic/orthotic part, a scaffold with a controlled pore pattern or an instrument casing; automatic generation of orthographic and sectional views from the model.
  15. 11Sheet composition, plotting and export for 3D printing Composition of a complete sheet with title block, sectional views and dimensioning for the component of Experiment 10; plotting to scale; export to PDF/DXF and to STL, with slicing parameters examined and the effect of orientation and layer thickness on the printed part discussed.
  16. 12Mini project with an introduction to AI assisted bio design In groups of two or three, students prepare a complete drawing set — equipment or device drawing with a 3D model, plus the associated flow diagram or layout. The session includes a demonstration of image derived (CT/MRI) patient specific modelling, bioprinting workflows, lab on chip/microfluidic layout, and AI assisted design and shape optimisation in biomedical applications. Evaluation by presentation and viva voce.
  17. 6Internal assessment, viva voce and end semester practical examination
  18. 3Total
  19. 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 Biotechnology Stream (BT) 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 Biotechnology Stream (BT), rather than generic examples.
  • To develop the ability to prepare equipment, facility layout and device drawings relevant to bioprocess and biomedical practice, and to introduce 3D modelling and printing as used in the bio 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 equipment, flow diagrams and facility layouts for bioprocess and biomedical practice. 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.
