2 Section II Question 11 Correctly states the purpose of a colour palette 1 A colour palette enables the selection and application of a range of colours. Question 12 Provides advantages of drawing in oblique projection when compared to 3 isometric projection Provides an advantage of drawing in oblique projection 2 Provides some relevant information 1 Drawing the object in oblique allows the curve and circular hole to be drawn parallel to the viewing plane is easier to draw as a compass can be used. In contrast isometric requires circles to be drawn as ellipses which is more difficult. 2

3 Question 13 Correctly projects the TSS of face A and the circle 3 Demonstrates general understanding of TSS of auxiliary view 2 Sketches a projection of the face or circle 1 3

4 Question 14 Correctly uses MP perspective projection to accurately draw the block on 3 the axis Demonstrates general understanding of MP perspective of L-shaped block 2 Demonstrates some understanding of MP perspective 1 4

5 Question 15 Demonstrates a detailed understanding of specific information required for council on the DA when plans are submitted 5 Demonstrates a general understanding of specific information required when plans are submitted for a DA 3 4 Demonstrates basic understanding of information for a DA 1 2 Answers could include: set back distance of building development to site boundary shadow analysis to determine effect of development on surrounding properties contour intervals to assist with communication of levels and gradients on site landscaping proposed landscaping including flora types environmental impact eg waste management flood/bushfire regulations stormwater traffic congestion material selection/height restrictions. 5

6 Section III Question 16 (a) Provides a good understanding of the main features of the purpose of risk assessment in the graphics industry 5 Provides a relevant industry example Provides an understanding of the main features of the purpose of risk assessment in the graphics industry 4 Provides a relevant industry example Sketches in general terms the purpose of risk assessment in the graphics industry 3 Provides an industry example Provides a feature of the purpose of risk assessment in the graphics industry 2 May provide an example Provides some relevant information 1 The purpose of risk assessment within the graphics industry is to identify, eliminate, remove or minimise hazards for workers within the industry. For example, the majority of people working in the graphics industry spend the majority of their time sitting at a desk in front of a computer monitor. A risk assessment of the work process would identify the risk of incurring a repetitive strain injury (RSI) of the wrist from prolonged use of a mouse. The process of risk assessment would identify measures to eliminate or mitigate the risk. In the example given, mandated rest breaks allow for a safer work situation. Answers could include: A risk assessment involves measuring the degree of harm that could be inflicted on someone who is exposed to a hazard. WorkCover (NSW) action plan for risk assessment: 1 Work out how severe the harm could be 2 Work out how hazards may cause harm 3 Work out likelihood of harm occurring. The purpose of risk assessment is to determine the harm that could happen to a worker in the graphics industry. Completion of a risk assessment indicates that risks have been identified, including the severity and likelihood of the harm to a worker. Once a risk assessment is done, the risk can be controlled by using various hazard controls. A risk assessment allows workers in the graphics industry to work safely due to the identification, measurement of severity of harm, and control of hazards. This not only means fewer injuries, but also fewer days sick leave which means a more efficient industry in both costing and time. 6

7 Question 16 (b) Provides a detailed explanation of the influence of particular historical developments on the graphics industry 10 Provides a logical and cohesive response that includes industry terminology and specific industry examples Provides an effective explanation of the influence of particular historical developments on the graphics industry 8 9 Provides a logical response that includes industry terminology and industry examples Provides some explanation of the influence of particular historical developments on the graphics industry Provides a response that includes industry terminology and industry examples OR 5 7 Provides a detailed explanation of the influence of ONE particular historical development on the graphics industry Provides a response that includes industry terminology and an industry example Attempts to provide explanation of the influence of particular historical developments on the graphics industry 3 4 Communicates information using industry example(s) Provides some relevant information relating to historical development(s) 1 2 Answers could include: The popular commercial application of plastic in 1960s and 1970s brought about changes in material used for drawing stock. Tracing paper was replaced by the more durable drafting film. This allowed for a more robust material which was not affected by humidity or moisture. Precision engineering and manufacturing, together with an ability to manufacture to finer tolerances, allowed for mechanical pencils to be produced at different graphite diameters. This change had a profound effect on the graphics industry, whereby draftspeople no longer needed to keep pencils sharp. Drawing to standard was easier with mechanical pencils as lines with different thicknesses could be easily drawn. Computer technology has influenced the graphics industry in extraordinary ways. Computerisation has allowed for CAD to replace traditional drawing workflows. The benefits of CAD are many and varied. Revision editing is easier and quicker, not requiring a total redrawing of a project. CAD and 3D modelling have influenced how clients view their designers solutions 3D walkthroughs and 3D printed objects are a result of computerisation of the industry. 7
