Marker efficiency doesn’t necessarily imply optimum fabric usage
CAD makes pattern drafting easy and accurate
marker making, accurate grading,
easy calling of older styles, pattern
manipulation to generate new styles
from old pattern, checking of fits, etc. important feature which the operator
must check with their pattern master.
B-spline is one of the tested and
commonly used techniques.
It is essential to buy digitiser and
plotter with CAD Draping technique of pattern
making is not possible in CAD
WRONG WRONG
Rather you should never buy digitiser
with CAD. Every CAD has ‘pattern
design module, where you create
any pattern directly on screen. Old
habits never die. Digitiser promotes
old practices to continue, i.e. making
pattern on paper and then inputting
the pattern to computer by digitising
it. This is not only a waste of time
but also compromises on the in-built
accuracy. In the absence of digitiser,
existing pattern maker also learns
to operate CAD to make pattern
directly on computer. An input device
(digitizer of scanner) is still required
by organizations to probably input the
old paper patterns to CAD. Though drafting is a commonly used
module in CAD, draping module is
also available with several brands,
commonly called as 3D to 2D
flattening.
Smoothing of curves is not possible
in CAD as it is in manual method
WRONG
CAD rather offers different variations
of smoothing techniques. Actually
there are different smoothing
techniques available with different
brands of CAD. Probably this is one
CAD is not for me as my master
loves to draft real size pattern
WRONG
Celebrated pattern makers across
the world resisted use of CAD citing
several lacunas. Miniature size
drafting using mouse and keyboard
(rather pencil and hip curve) was
a bone of contention for lack of
realistic feeling. Actually to woo
pattern makers, CAD manufacturers
have gone all the way to make real
size electronic drafting board and
real size L-curve and French curve,
etc. To draw real size pattern,
which automatically input to the
computer, technology is available but
it is expensive. You can have manual
drafting experience as well as CAD
benefits simultaneously.
