IntroductionCAD for Fashion and Textiles Jimmy Lam The Hong Kong Polytechnic University
Agenda • Introduction • History • Application • Benefits • Drawback • CAD in ITC
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.
History • 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
Applications of CAD The National Knitwear Association and A. Grudier Consulting conducted a survey of 228 apparel manufacturers in 1995.
Some CAD Applications by Function • Merchandising • Design • Marketing
Merchandising • Line selection • Product selection • Costing • Product quality What is the CAD used for Merchandising? CAD is used for Visual Presentation for Merchandising process

Marketing • Advertising • Catalogues • Magazines photos • Video • Newsprints • Labeling and packaging • Story boards • Retail boards
Design Using CAD • CAD is the most visible, producing exciting new patterns for fabrics Christian Dior, Autumn/Winter 01/02
Influence of the computer on textiles begins at the textile design stage and continues through manufacturing, marketing and retailing

From internet point of view: the internet allows users to browse through designer collections at home: • http://www.isseymiyake.com/ • http://www.johngalliano.com • http://www.landsend.com
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
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
The role of computers in textile and fashion industry continue to grow • The industry is looking for designers and merchandisers who are computer literate
Some Drawbacks • Cost • Designer – machine operator – lost creativity • Feel lost without the tools of artists • Time to fully realize the system’s capabilities

Questions • Any limitations for CAD application in textile and garment industry? • Can CAD system replace traditional sample production process?
PRIMAVISION (TCX) – located in QT608Textile and Fashion Design System • Design system famous for its speed, stability and user-friendliness. • Easy-to-use graphics tools for fast style, pattern and colour development, catalogue and storyboard creation. • Design collections using libraries including Silhouettes, Woven Constructions, Accessories, Knit Structures, Textures, and Materials. • A variety of professional modules for knit, weave and textile print design.
Adobe Photoshop/ Illustrator – located in QT602 General Purpose Design System • Image editing • Common software used in fashion design/ fashion presentation/ graphic design • Compared to PRIMAVISION it is more user-friendly and the cost is much lower
Special Purpose Garment Design System located in C041 (weaving lab.) • Tajima Embroidery Machine Designed for high speed operation at 1,000 stitches per minute and quieter environment.
Rapid Sampling System: Weaving CAD/CAM (1) • Digital Weaving, Norway AS
Rapid Sampling System: Weaving CAD/CAM (II) • AVL looms – compu-dobby Input and edit a design on screen and immediately execute it on the loom. It's still handweaving, but with greater efficiency and infinitely more creative control.
Rapid Sampling System: Digital Printing located in C042 (dyeing lab.) • TexPrint – digital printer Editing or retouching the images. Colour Reduction Tools, Automatic Repeat Setting Tools, and Graphical Editing Tools.... enable the user to process the images for final printing. Possible to process complex images, and in no time, the image is ready for printing in different permutations and combinations. Supports colour separations for specific colours and as per the planes for e.g.: [RGB, CMYK]
Questions • Discuss the CAD features for rapid sampling for weaving loom • Discuss the CAD features for digital printing for textile printing.
