CAD is industry specific design system using computer as a tool. CAD is used to design anything from an aircraft to knitwear. Originally CAD was used in designing high precision machinery, but slowly it found its way in other industries. In 1970's it made an entry in the textile and apparel industry. Most companies abroad have now integrated some form of CAD into their design and production process.

Automation is not only used for substituting the labour, it is also adopted for improving quality and producing quantity in lesser time. However, a CAD system is only as good (or as bad) as the designer working on it. Computer only speeds up the process of say repeat making, colour changing, motif manipulation etc.

Textile Design Systems. Woven textiles are used by designers and merchandisers for fabrics for home furnishing and for men-women-children wear.

Most fabrics can be designed using a CAD system for textiles. Similarly embroideries are also developed at CAD workstations.

Knitted Fabrics. Some systems specialise in knitwear production and final knitted design can be viewed on screen with indication of all stitch formation. For instance a CAD program will produce a pullover graph that will indicate information on amount of yarn needed by colour for each piece. Another example of the new technology in the industries using a yarn scanner which is attached to the computer scans a thousand meters of yarn and then simulates a knitted/ woven fabric on-screen. This simulation will show how the fabric will look like if woven from that yarn.

Printed Fabrics. The process involves use of computers in design, development and manipulation of motif. The motif can then be resized, recoloured, rotated or multiplied depending on the designer's goal. Textures and weave structures can be indicated so that printout either on paper or actual fabric looks very much the way the final product will look.

Sketch Pad Systems. These are graphic programmes that allow the designer to use pen or stylus on electronic pad or tablet thereby creating freehand images which are then stored in the computer. The end product is no different from those sketches made on paper with pencil.

Texture Mapping: 3D Draping Software. This technology allows visualisation of fabric on the body. Texture mapping is a process by which fabric can be draped over a form in a realistic way. The pattern of the cloth is contoured to match the form underneath it. The designer starts with an image of a model wearing a garment. Each section of the garment is outlined from seam line to seam line. Then a swatch of new fabric created in textile design system is laid over the area and the computer automatically fills in the area with new colour or pattern. The result is the original silhouette worn by original model in a new fabric.

Embroidery Systems. The designs used for embroidery can be incorporated on the fabric for making garment. For this special computerised embroidery machines are used. Designers can create their embroidery designs or motifs straight on the computer or can work with scanned images of existing designs. All they need to do is assign colour and stitch to different parts of the design. This data is then fed into an embroidery machine with one or multiple heads for stitching.
