Every vendor lists what the software does. Fewer are willing to say what it does not,
and a shop that finds out afterwards feels cheated even when the product is good. So,
plainly:
It will not make a bad measurement good. A draft is only as accurate as
the numbers written into it. If two people in the shop take the waist at different
places, the stored record is worth nothing. Agree where each measurement is taken and
keep it the same for everyone - that costs nothing and it is the single largest
improvement most shops can make.
It will not cut the cloth. The draft and the printed pattern are the
output. Cutting is still a skill, and the machine that cuts is a separate purchase with
its own cost.
It will not teach the shop the garment. The system drafts what you ask
for. Deciding that a customer needs a deeper yoke or a different flare is still the
cutter's judgement, and no software replaces it.
It will not pay for itself in a shop that has spare capacity. The return
comes from work that was previously turned away, from alterations that stop coming back,
and from cloth that stops going into the scrap bin. A shop with none of those three has
little to gain, and should say so out loud before buying.
