From state-of-the-art luxury solutions, CAD has become a basic necessity for any large or small-to-medium apparel manufacturers today. There are several myths about potential benefits of apparel CAD that lead to over-expectations which requires clarifications. Installing CAD means getting rid of your pattern master WRONG You do require a pattern maker to operate CAD. Imagine you are asked to draw a straight line without using ruler; if you compare drawing a straight line with pattern drafting and ruler with CAD, then CAD is just like a tool for pattern making. Similar to a mechanical drafting tool, CAD is an electronic drafting tool to help drafting pattern accurately, quickly and with consistent quality. Installing CAD will always result in enormous fabric savings WRONG CAD has a module called marker making. Patterns are being laid in a given width of fabric, either manually or automatically, to calculate length of fabric required. Arrangement of patterns or nesting (as it is scientifically called) is subject to numerous permutations and combinations. While making marker manually, all possible permutations and combinations are not possible to try due to time constraint, resulting in possibilities of finding ‘still better combinations’. While using automatic mode of marker making, all possibilities can be tried before arriving at the best possible combinations rationally. The marker making operator due to its shear experience will know the best combination while a new operator, even though using CAD as a tool, will not be able to match same efficiency. In reality maximum CAD users use manual options of marker making, i.e. using human intuitions/gut feel to find the best combinations and using CAD only as a tool. Marker making efficiency actually improves with experience over the years, if you are using same or similar product types. Due to shear experience the marker making operator will know the best combination while a new operator, even though using CAD as a tool, will not be able to match same efficiency; this flusters many organizations after acquiring CAD. This is more prominent in domestic market as the product variety and probability of improving marker efficiency is less. It is unwise to imagine that any CAD operator will beat your experienced marker maker. CAD as a tool do help in making marker, like you have a full 2-metre view of fabric length in front of your screen (to see where gap exists and where blocking could be possible), which otherwise is not possible. Better marker efficiency always means better utilization of fabric WRONG While marker efficiency is important, marker length is equally important. 46 Apparel Online Bangladesh | MAY 2018 | www.apparelresources
