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.
