SUGGESTED 66% OF COURSE DELIVERY TIME FOR THIS MODULE. IT IS NOT EXPECTED THAT TOPICS WILL BE GIVEN EQUAL DELIVERY TIME
1: FIRST PRINCIPLES
The first principles are the basic knowledge and skills sets needed prior to study of the basic concepts of Technical Graphics. These first principles are learnt prior to plane geometry concepts. For some learners, especially those who have successfully completed Technical Graphics – Foundation Level 2 or equivalent, this topic will serve as a revision of basic knowledge and skills previously acquired.
Basic Knowledge
Introduction: Graphical language is used to convey information, standards and conventions. How drawings can overcome language barriers.
Equipment: Types of pencils, pens, ink, erasers, compasses, protractors, templates, guides, flexi-curves, French curves, dividers, rulers, scale rulers, set squares, T-squares, drawing machines, and tables. How to use such equipment correctly and safely. Except for specific paper media-based tools, they are device independent.
Paper: Different types, sizes and thicknesses of paper.
Skills:
- definition of point, line, circle, arc, curve, line types of each of these
- correct way to hold a pencil or pen
- correct way to use a compass and dividers
- correct way to mount paper to drawing table
- draw borders and title blocks to correct set-out
- lettering
- drawing a straight line to a specified length
- notation of points
- bisection of line
- perpendicular from a point on line – construction of
- perpendicular from a point to a line – construction of
- line division
- angles by radius
- bisection of angles
- copying of angles
- construction of triangles, scalene, equilateral, isosceles
- inscribing a triangle
- circumscribing a triangle
- true length lines, horizontal planes and vertical planes.
2: GEOMETRY
Learners will initially carry out a range of hand sketching and technical drawing exercises in this topic to develop conceptual knowledge in plane and solid geometry, as well as translating concepts and problems from 2D to 3D.
2.a – Plane Geometry
- Geometric construction – line and angle bisection, construction of perpendiculars, reproduction of figures, construction of angles/triangles, inscribing/circumscribing circles
- Polygons – regular, constructed in given circles or on given side
- Conic curves – different methods of constructing the ellipse, parabola and hyperbola
Examples: roof design, ballistics, self-supporting archways in civil engineering and architecture, satellite dishes
- Loci – helix, spiral, roulettes, involutes and curves generated by mechanisms
Examples: plotting the path of a moving point such as the opening of a garage door, shapes such as a helical stairway or Archimedean spiral ceilings
- Simple cam design to include wedge, roller and flat followers on same axis
Examples: machines and automotive engines.
2.b – Solid Geometry
- 3rd angle projection advanced drawings and recognition of 1st angle
- True lengths of lines inclined to either or both planes
Examples: engineering, architectural applications and sheet metalwork
- Dihedral angle
Examples: roof construction, mining, aeronautical and nautical contexts
- Advanced examples of the intersection of right solids, spheres and toruses
Examples: mining, construction or engineering contexts
- Surface development of right and oblique solids, cones, cylinders, prisms and pyramids using parallel line, radial line and triangulation methods
Examples: engineering, sheet metalwork, steel fabrication and ducting contexts
- Auxiliary views of planes and solids
Examples: engineering and architectural contexts
- Advanced examples of true shapes of solids cut by horizontal, vertical and inclined planes
Examples: plumbing, air conditioning engineering, sheet metalwork, steel fabrication and ducting contexts
- Inter-penetrations between solid objects
Examples: house extensions when the roof sections need to be joined or plumbing
- Co-ordinate Geometry – points, lines and planes
Examples: geographical, navigational and geological contexts.
2.c – Structural Analysis
- funicular diagrams
- vector diagrams
- Building Information Modelling (digital applications)
- awareness of finite element analysis (FEA)
Examples: geographical Applications include bridge stresses, calculation of loadings on beams or guy rope forces.
3: DRAWING AND PRESENTATION TECHNIQUES
Learners will develop skills and techniques in the use of conventional and contemporary graphic techniques including the use of CADD systems. Learners will gain an understanding of the drawing and presentation conventions and practices within a range of industry areas.
Computer-Aided Drafting and Design (CADD) systems will be used to create drawings or models as part of the design process. These skills and knowledge transfer to Computer Aided Manufacture (CAM) involving properties of materials and manufacturing principles and processes. Digital fabrication provides a strong context in a senior secondary education environment. 3D printers and small CNC machines such as laser and vinyl cutters are examples of how CAM can complement CADD.
Standard Drawing Practice
- current Australian Standard Drawing Practice (AS 1100, ISO standards for CADD) for architectural, engineering and digital drawings.
Freehand Sketching and Rendering
- freehand sketching to support preparatory work and communication for initial design development.
Perspective drawing
Orthographic drawing
- Orthogonal projections in 1st and 3rd angle including auxiliary views.
Pictorial drawings
- isometric, oblique, perspectives, axonometric, planometric representation of ideas (freehand, notated graphics).
4: DESIGN PROCESS AND PRINCIPLES
A study of design process and principles including, but not limited to:
- situational analysis
- design brief
- research and investigation
- working drawings
- possible solutions
- preferred solution
- evaluation.
MODULE 2 – THE DESIGN FOLIO
SUGGESTED 33% OF DELIVERY TIME
Task
Learners are required to undertake a major inquiry in an area of interest demonstrating the design process and knowledge of the chosen industry or discipline. This process addresses the requirements outlined below and in the current TASC published external assessment guidelines for this course.
The folio requires a link with a relevant technical graphics industry or discipline context. Learners will be encouraged to undertake a problem-based design solution in liaison with an industry professional (e.g. an architect, engineer, surveyor, fabricator or manufacturer). The contacts that learners make with industry and professional bodies/people will be pre-approved and overseen by teachers. Learners will be required to contextualise their learning within a relevant industry or discipline when devising the design brief and undertaking the requirements of the Design Folio. Learners will convey their understanding of the conventions, drawing protocols, roles of team members and emerging trends within the industry or discipline area.
The study will be futures-oriented in that it will focus on the knowledge, understanding and skills required in the 21st century. It will recognise the changing nature of work in the context of global integration and international mobility, Australia’s future in the region, technological innovation and increasing use of technology in society and work. Awareness of the roles of high value and leading-edge industry research and development (R&D) organisations are also developed through the study.
Requirements
For the chosen area of interest, learners will prepare a:
- design brief
- description of the evolution of the design process
- range of drawing and presentation techniques.
The folio will contain between 25% and 50% output from CADD systems.
Possible areas of study
- mechanical engineering
- civil engineering
- electrical/electronic engineering
- aerospace
- marine engineering
- marine architecture
- automotive
- landscape architecture
- domestic architecture
- interior design
- industrial architecture
- product design
- cartography
- surveying.
