THE CAD WORLD understanding CAD and its Advantages By KRUTIKA GARG
Automation in textile isn’t new, it is known for numerous decades now, strengthening the word “Development”. It’s present everywhere in textile, in pre-planning to designing to manufacturing to quality and finally to shipping. Be that as it may, the enlivening is about the most fundamental need of automation in Textiles, the CAD systems, Computer Aided Designing. As the word in itself explain the side of Design, it also, explains the computerized part of it. That implies, it is significantly less demanding and speedier than any manual method of creating design. However, CAD takes part in both Design illustration and Pattern Drafting, though both the errands have distinctive programming modules and on occasion even the provider brands could be unique. Here’s to note, that the speed of the task does not just applies to the design illustration, however to more technical and specialized part which is known as First Pattern development, a base pattern to change over the design in to an actual product, the first sample.
This procedure of pattern advancement is an advantageous occupation profile for all the pattern masters. This computerized arrangement rearranges the mind boggling and untidy procedure of drafting through manual means like paper, scissors, rulers and so on. Truly, that is the aim of any accessible CAD in the business. While garment industry has been utilizing the CAD innovation to different procedures of pattern adjustments or modifications and numerous different advantages of grading and marker making they actually missed to utilize this advancement for its fundamental target, that is pattern drafting.
This all is about the right utilization of innovation to increase greatest advantage as far as time, fabric consumption and organized working method is concerned. Ultimately leading to finances.
The present situation offers a great facility to DIGITIZE any paper pattern and exchange the same to PC, already installed with certain CAD, and perform the advance tasks of various alterations or modifications. There are numerous methods, as easy as clicking a photo, accessible to Digitize and transfer any manually made paper pattern to the system. Leading towards performing similar tasks twice and consume
considerably more time with no guarantee of accuracy in the photo clicked pattern.
Manual construction of paper pattern is a slower process than that of computerized one. And not to overlook, the curve points and notches missed during the digitizing needs to be reworked- demanding even more time for smoothening the curves and addition of notches on correct measurements or angle. As yet being the piece of the CAD bundle, digitizing is unmistakably not an aid but rather only an assistance, to be utilized as a part of not very many game plans. Be that as it may, this has turned into a consistent practice without considering the disadvantages it offers. There are big players genuinely utilizing the pattern drafting technology through CAD and spares considerably more time to plan ahead, in contrary, there are many not using the digital solution to its potential.
The technology does have advancements of options provided by developers for optimum utilization of CAD systems by programming them for further intelligence. Odds of mix-ups or passing up a major opportunity for a specific guideline are totally ZERO. Provided, a good pattern master is the CAD user. Presently, CAD systems have only few options, let’s say fifteen at max, to be recalled on fingertips and empower you to perform over hundreds of steps to create and modify patterns. Modification clearly states the process of smoothening of curves with least no. of points or adding the external elements like notches in different shapes, yet most vital is the process of Grading. That takes a colossal measure of time and reciting of X and Y axis on every grading point. This is not enough, issue with grading drastically varying from size to size and point to point is another undertaking to pull back the diligent work and demotivates to proceeds with experiments or new projects/styles. But with new technique of simpler grading tables and clever choices of just directional grading (to be done just with left, right, up and down notations) it is more encouraging to sample new products, with no hesitation.
The ease CAD provides for marker planning spreading & cutting process is another appreciable point. Marker planning was traditionally an occupation of expert human force in cutting department. Whereas, CAD is fully capable of doing the job with marker planning modules and Automarkers, which within seconds can provide number of alternatives reasonable according to style of patterns, fabric width or texture. Confusing stripes, plaids or placement prints could easily be avoided by empowering the computer to perform the task independently, of course the parameters are needed to be set as per one’s requirements.
Auto-markers have often proven to be superior than manual marker planning as the ideal utilization of fabric could be accomplished through them. These can help in fabric lay planning considering consumption per garment and ultimately leading to total fabric requirement for a specific order. Costing per piece or for entire order, Shrinkage, cutting buffers, identification of fabric defects are a few additional features provided in NEW GEN CAD. It is well known that these markers could directly be incorporated to the automatic cutters and the cutting can begin automatically. The astounding point is even the direction of cutting and movement of blade could likewise be guided to effective optimization of cut path within the CAD.
Through various contextual analyses, it is seen that up to 65% of time could be spared through CAD for pattern making, grading and marker making. Up to 25% of fabric and other resource wastage could also be avoided in product manufacturing, provided the CAD is being utilized completely to its potential.
