1.16-1.17 Design strategies and design communication GapFill

Perhaps the most common method of communicating design ideas to others is to use a form of  flow chartfirst anglesystemsfreehand sketching.   This method can be in 2D or 3D and  first-angleobliqueisometricsystems projection drawn at 30 degrees to the horizontal to show ideas in 3D.   A more realistic 3D form of communication which involves the use of vanishing points is known as  orthographic projectionexploded projectionflow chartsperspective drawing.    Exploded viewsOblique projectionsSystem and schematic diagramsPerspective drawings are best used when designing and communicating electronic circuits.   Working or orthographic drawings are in 2D and can be drawn in first or  secondthirdfourthfifth angle, and are used to show dimensions and are drawn to scale.     Systems diagramsAnnotated drawingsExploded viewsIsometric projections show constructional detail such as joints, and are often annotated to describe how parts fit together.   Computer modelling, often using  PVCCADPCBCAM or mathematical modelling, is a great way to be able to convey design ideas and even run tests and simulations on products before they are manufactured.    Asystems thinkingIterative designCollaborationUser-centred design is a strategy that allows designers to draw upon the specialist knowledge and experience of others.   However, a strategy that focuses on the needs of the client or user and involves them throughout the process is known as  iterative designsystems thinkingcollaborative designuser-centred design.   A method used by those who design electronic products is  collaborationsystems thinkingiterative designuser-centred design, which makes use of feedback loops when testing.     Building3D modellingTestingDestructive testing is a great way to be able to convey design ideas before moving on to making products for real.
