IntroductionWhat is CAD

CAD (Computer Aided Design)

Any part of the design process utilize the computer as a tool = CAD

In textile and fashion industrials, CAD include graphics applications used for purposes of visualizing design, technical specification and functions.

4

CAD was originally developed on industry-specific or “turnkey” system

CAD is a mainstream tool for the competitive market

Most companies have integrated some form of CAD technology into their design and production processes

History

5

Applications of CAD

To create colourways 65%

Printed fabric design 60%

Merchandising presentations

48%

Knit designs 41%

The National Knitwear Association and A. Grudier Consulting conducted a surveyof 228 apparel manufacturers in 1995.

14

Common use of CAD : design of surface pattern for fashion and furnishing fabrics

The system allows complex designs to be completed in short time

As software packages are increasingly specialized, easier for designers to work with design, e.g. PrimaVision, photoshop, illustrator

15

Benefits Increase productivity Reduce product development time Increased creativity to improve conceptual

design Reduced cost of samples and prototypes Lower reject rate Create universally understood

communications among all phases of operation

16

Application Benefit

Textile design Time cut 50% - 75%

Reduce sample cost

Lower reject rate

Garment design Saves times in approval process

Saves costs in material and labour

Evaluate designs Respond to changes quicker

Virtual presentations to consumers

Adapt to consumer reactions

Stimulate designer’s creativity

More time for development

17

Online catalogue Reduce costs and times

Retail sales feedback Increase customer satisfaction

Work on design with customers

Increases customer satisfaction

Improved quality

18

The role of computers in textile and fashion industry continue to grow

The industry is looking for designers and merchandisers who are computer literate

19

Some Drawbacks

Cost Designer – machine operator – lost creativity Feel lost without the tools of artists Time to fully realize the system’s capabilities
