- 2. Introduction CAD, or computer-aided design and drafting (CADD), is technology for design and technical documentation, which replaces manual drafting with an automated process. If you're a designer, drafter, architect, or engineer, you've probably used 2D or 3D CAD programs such as AutoCAD or AutoCAD LT software. The Apparel Computer-aided design (CAD) tool provides great ease to the cutting department and saves a lot of money and time. The system not only can design pattern, modify pattern and grading in the computer, but also can import manual designed patterns to the software by digitizer. Then go to grading, nesting, printing and plotting. Then go to grading, nesting, printing and plotting. Manual graded patterns can also be imported to our system for modifying and saving.
- 3. Every coming generation is more fashion-conscious so there is a huge demand for new-fangled weave designs. It is not easy for them to remain competitive, by merely depending upon the traditional way of designing, because today's design becomes out of fashion tomorrow. Any textile industry will think about improving efficiency, maximum utilization of resources, and improvement in services for customer satisfaction. A search of these elements leads towards the development and use of new technologies. As the proverb says "Creativity is one per cent inspiration and ninety-nine per cent perspiration." but computers have confirmed it wrong. They have made textile designing simpler, faster, more precise and enjoyable. The designer can create his motifs with a mouse or pen. Once the design is created, further process of editing the design i.e., clipping of certain parts, adding new shapes, changing the shapes, distortion, resizing, recolouration, colour reduction, replicating and combining as per the need can be done at the minimum possible time. Also, one part of the design can be altered without affecting the rest. Why CAD/CAM Is Necessary Today?
- 4. There are many CAD software solution providers for the garment. and textile industry. Here is a list of such popular CAD systems. •AccuMark Pattern Design Software by Gerber Technology. popular CAD softwares •Modrais by Lectra Systems. This automated high-speed nesting system dramatically accelerates the marker making process and cuts costs by analyzing multiple nesting solutions and delivering the one with the highest material utilization. Modaris Expert is the most advanced version of Lectra’s patternmaking technology. It helps you accelerate your product development process by allowing patternmakers to organize, store, retrieve and leverage essential digital assets of the garment development process with ease.
- 5. It combines powerful 2D design and true to life 3D visualization in a single platform that answers the needs of apparel and technical textile industries. •Optitex Pattern Design software by Optitex. "SDS-ONE APEX" series supports everything from planning and design, colorways and realistic fabric simulation to 3D virtual sampling. It contributes to sustainability by eliminating waste from the fashion supply chain. •SDS-ONE APEX3 from Shima Seiki.
- 6. TUKAcad is an intuitive CAD software for digital pattern making, grading, and marker making. It's flexible and enough for fashion businesses of all sizes, freelance designers, and students. •TUKAcad by Tukateck Inc. •Fashion Cad by Cad Cam Solutions Australia Pty. Ltd •PAD System. •GT CAD by Genuine Technology and Research Limited. •CAD.Assyst by Human Solution Assyst AVM.
- 7. Features of a CAD Software 1. Solid Modeling: With this, any model can be constructed using parameters like measurements, physics etc. and can be edited at any point in time be it undoing or modifying it keeping the original as it is. 2. Surface Modeling: With CAD, solid components can be given texture, details by trimming, stitching and joining different surfaces to create the final shape of the model. 4. Drafting details: 3D drawing can also be created from a 2D drawing of the components or assemblies only by providing the parameters and dimensions. 3. Assembly: With CAD, assembling of the models created in solid or surface modeling can be done to get an overview of how the product will look in the final assembling allowing us to make changes accordingly. It is also used to see actual fittings and the working of the assembled model.
- 8. The CAD software is being used on a large-scale basis by a number of engineering professionals and firms for various applications. The most common application of CAD software is designing and drafting. Here are some of the benefits of implementing CAD systems in the companies: Benefits of the CAD Software 1. Increase in the productivity of the designer. 2. Improve the quality of the design. 3. Better communications. 4. Creating documentation of the design. 5. Creating the database for manufacturing. 6. Simulations. 7. Elimination of inventory.
- 9. Factors to consider before installing a CAD system Installation of the software for any company should depend upon its requirement. Some of the factors that must be considered while buying or upgrading a CAD system/software can be as: • Buying something according to the requirement and not to the extra features or brand value. • Determining the budget that must be allotted for the software and the expected ROI (Return on Investment) from it. • Initial hardware present must be checked against the requirements of CAD software vendors otherwise the software may not function properly. • The software must have a user-friendly interface for the operator to feel comfortable using it. • Asking for a free trial version of the software to check its compatibility with resources available
- 10. Most of the software comes with a different package. The basic level is often free or priced less but comes with a lesser number of features, but more features can be added or upgraded with paid modules More the number of tools, more will be the cost. They also come with the subscriptions system where we can use the license for a maximum period which we have already paid for. For a glimpse of the pricing, I’m taking examples from some of the major CAD systems. Gerber and Lectra have systems starting from $10,000 and with a full set-up of software (more than one workstation), drafting table, digitizer, plotter and computers at $40,000. Master Pattern from PAD is priced at $4,500. TUKATECH has a price of $7,500 for basic program. WildGinger is priced under $4,000. AutoCAD and TurboCAD are ranged from $100 to $400 depending on the features. Pricing is often based on individual packages designed for company needs thus they should be bought depending upon the need the company. CAD Software pricing About the pricing.
- 11. The way in which technology is improving, we can expect a future wherein the entire process of garment manufacturing would be done through machines by a powerful algorithm and with very little human presence. With On-demand Manufacturing becoming the new way of production CAD has already influenced the industry with its 3D visual rendering of garments on to the human figures. It will also play an important role in a 3D printed fashion which is expected to becoming the next big thing in the fashion industry. With CAD, there is no turning back to the era of hand-drawn design because of its huge potential of changing this diverse industry, pushing forward the boundaries of fashion. Future of CAD in the apparel industry
- 12. The industry survey on the apparel CAD systems underlined the benefits of the use of the same in terms of productivity, quality, efficiency etc that helps to develop the business and attracts new customers. Reduction in lead-time is a great advantage, which provides the manufacturer with a much-needed breathing space in the ever-growing competitive market. However, there is a further scope for the study to find about the market share and growth of CAD companies in the Bangladeshi market and the reasons for the popularity of the more accepted system. It is important to know how rapidly the apparel Industry is responding to the intervention of Information Technology in the cutting room. Another vital thing that remains in the scope is the requirement of investments and return on investments. Conclusion
