Module Description:
The module introduces the student to fundamental Engineering Drawing principles, thus providing the
student with visualisation and drafting skills which are fundamental to engineering design concepts of
Mechatronics. This module takes a software based approach to developing drawing skills and gives an
introduction to CAD software (AutoCAD) that is elaborated on follow-on modules, while simultaneously
reinforcing engineering drawing concepts.

Module Content & Assessment
Indicative Content
REGULAR AND IRREGULAR FIGURES
Construction of triangles, quadrilaterals and polygons from given data.
PROJECTION OF SOLIDS
Principles of projection: planes of reference, first and third angle projection, auxiliary planes, sectional planes. Points defined by their
rectangular co-ordinates. Orthographic projection of solids such as cube, right and oblique prisms and pyramids and other simple irregular
solids in various positions so that the axis of the solid is not inclined to more than one principal plane. True shape of sections. Auxiliary
projections showing new plans and elevations.
DEVELOPMENTS
Developments, of the surfaces of right prisms, pyramids, and their truncations and combinations. Development of surfaces of other simple
solids. Development of the surfaces of oblique prisms, pyramids and their frusta. Note: Prisms and pyramids to include cylinders and cones.
CONIC SECTIONS
Definition of focal sphere, focal points, directrix and eccentricity. Drawing of conic sections. The ellipse, parabola and hyperbola as plane
loci. Construction of tangents from points on the curve and from outside the curve. Principal properties of the conic sections.
PICTORIAL PROJECTION
Isometric projection of solids from given data, from models and from orthographic projection. Use of isometric scale: Principles of oblique
projection: cavalier and cabinet. Oblique projection of solids from given data.
STANDARD SPECIFICATIONS AND CONVENTIONS
B.S.I. Engineering Drawing Practice. Layout of drawings, lines and linework, lettering and numerals, systems of projection Views on
drawings, general, number of views, partial views, simplified representation of symmetrical parts, adjacent parts. Sections, general, cutting
planes, hatching, types of section, parts and features of parts not normally sectioned. Principles of dimensioning, general, functional
dimensioning, projection lines, dimension lines and leaders Dimensions, linear dimensions, angular dimensions, redundant dimensions.
Methods of dimensioning common features, diameters, radii, sizes of holes, positioning of holes and other features in circular arcs, countersinks, counter-bores and spot-faces, bolts, nuts and washers, screw threads, keyways and taper features. Abbreviations and symbols.
Toleranced dimensions, general, application of tolerances, tolerance on individual linear dimensions, tolerance on functional dimensions.
Machining and surface texture symbols, indication of surface texture.
ORTHOGRAPHIC PROJECTION
Use of standard specifications and conventions in producing engineering drawings to scale; in first or third angle projection, including
auxiliary views and sections in the following cases:- (i) Fully dimensioned freehand sketches of engineering components. (ii) Working
drawings of engineering components from given assembly drawings (iii) Preparation of assembly drawings from given details of
components.
