Further sustainable practice can be achieved by using representative virtual shapes
from a survey. These scan shapes can be uploaded into virtual design systems (such as
Optitex and Assyst), where both contour and some free form clothing designs can be
created and patterns unwrapped and flattened (e.g., Morlock et al., 2016; Kung, 2012;
Kirchdoerfer et al., 2011; Krzywinski et al., 2005) from which patterns can be mor-
phologically graded or resized (Kung, 2012; Sayem et al., 2014a,b). See images in
Fig. 3.1.
In addition, two-dimensional cross-sectional data are being used to help evaluate
and select digital systems and identify air gaps between body surface and garment to
