IntroductionCAD in real world
CAD in the “real world” emphasizes the day to day productivity requirements to cope with in an ever demanding industrial environment.
This is an excitement and frustration in taking theory into practice and continually improving processes of design and product development.
The CAD process is viewed from the mass production on a large retain chain store of garment business in terms of design, quality, delviery and price.
Activity One2D Graphic Design
A computer tool with graphic capabilities allows user to scan in or create on screen many types of images and manipulate them.
The quality, capability and prices vary enormously in this technology.
Important issues are cost, colour, high image resolution, sensitivity to designer and links in the supply chain
Activity TwoPattern Design
A computer tool allows user to scan, digitise in or create pattern blocks on screen, apply grades and redesign pattern pieces where necessary.
Important issues are ease of use, speed of use and communication.
Examples on pattern design are rima Design System, Shima Design System (Industry-specified).
Examples on 2D Graphic design are: Illustrator, Coral Draw, Photoshop (General-purpose design system)
Activity ThreeCosting Systems
A computer tool allows quick and easy access to standard minute, trim and fabric databases for the calculation of a full product cost.
As business grows, the need for accurate product costing and the monitoring of cost fluctuations become paramount.
Important issues are accurate data collection, maintenance, ease of use and interpretation into the design environment.
Example: General Sewing Data (GSD), Activity Based Costing (ABC).
How can you calculate product cost in sewing industry?
Time measurement? Piece rate?
Investment in CAD (1)
The world of product design is often seen as being artistic, emotive, unpredictable and uncontrollable.
This view can be due to historical and traditional behaviour patterns.
The introduction of CAD technology needs to consider the costs of product design while maintaining an atmosphere of creativity and innovation.
Key issues on CAD investment are:1) Education; 2) Cost and 3) Payback
