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 and ellipsoidal profiles of pressure vessel dished ends, and the helix of a coil heat exchanger and screw conveyor.
  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 hopper, a cyclone separator body and a rectangular to circular duct 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. 8Drawing of process equipment components Orthographic and sectional drawing of process equipment parts: a flanged joint with gasket and bolting, a vertical storage vessel with a dished end, nozzle and manhole, and a support saddle. Conventional representation of welds and of vessel internals; nozzle orientation drawing prepared for the same vessel.
  11. 9Block flow diagram, process flow diagram and P&ID Progressive development of the documentation of one simple unit (for example a pump–heat exchanger–tank loop or a batch reactor): block flow diagram, then process flow diagram with stream numbers and a mass balance table, then a P&ID with instrument bubbles, control loops, valves and line numbering. Symbols as per ISA 5.1 and diagram conventions as per ISO 10628.
  12. 103D modelling of a process equipment item Solid model of a shell and tube heat exchanger head, a distillation column section with a tray, or an agitated vessel with impeller, using revolve/extrude/pattern features; automatic generation of the sectional views and of an exploded pictorial view from the model.
  13. 11Plant layout, piping isometric, sheet composition and plotting Equipment layout plan and elevation of a small process area with access and maintenance clearances; a piping isometric of one line with fittings, valves, supports and a bill of material; composition of a complete sheet with title block; plotting to scale and export to PDF/DXF.
  14. 12Mini project with an introduction to 3D plant design and AI tools In groups of two or three, students prepare the documentation set of a simple process — PFD, P&ID, one equipment drawing and a layout — for a unit of their choice. The session includes a demonstration of 3D plant design and clash checking, digital twins of process plants, and AI assisted P&ID digitisation from scanned legacy drawings. Evaluation by presentation and viva voce.
  15. 6Internal assessment, viva voce and end semester practical examination
  16. 3Total
  17. 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 Chemical Engineering Stream (CH) 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 Chemical Engineering Stream (CH), rather than generic examples.
  • To develop the ability to read and prepare block flow diagrams, process flow diagrams and piping & instrumentation diagrams, which are the primary communication documents of process 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 PFDs, P&IDs, equipment drawings and layouts for a simple process unit. 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

  12. 1 and ISO 10628. 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.
