1. A pattern making method comprising: acquiring into memory of a computer, a multiplicity of different two-dimensional image slices of a human form; selecting by a processor of the computer, a panel of a portion of a pattern of a garment; mapping by the processor of the computer a metric computational rule for the selected panel to one of the two-dimensional image slices; acquiring by the processor of the computer a measurement of the one of the two-dimensional image slices; and, applying by the processor of the computer the mapped metric computational rule using the acquired measurement to produce a measurement for the selected panel.
