It will not fix a measurement taken wrongly. The draft is only as good
as the numbers entered. If two people in the shop take the waist at different places,
the stored record is worth nothing - and that costs nothing to fix, which makes it the
best value improvement in the building.
It will not know your fabric. The same draft behaves differently in
georgette and in raw silk, and heavily embroidered cloth drops after a few hours of
wear. Allowing for that is still the cutter's judgement.
It will not cut the cloth. A full-size printed pattern is the output.
Cutting remains a skill, and a cutting machine is a separate purchase.
It will not print on an ordinary A4 printer. Full-scale patterns need
a printer or plotter that takes continuous roll paper - the
plotter machine page covers what that
involves, and the price of the whole setup is on the
software price page.
