If you do your patterns in CAD, you can usually save the file as PDF and email it to anyone who can open the image in Acrobat. A grid overlay is useful for others to transpose the scaled down pattern up to full size.
For those with access to a wide format plotter the pattern can be plotted full size or even scaled up and down to accommodate smaller and larger sizes of the same proportion. This could work for a stoking for example.
Patterns for entire suits introduce so many variables that pattern adjustment may be pretty tricky. If you notice the M2M charts request as many as 20 or more measurements. So the permutations of what can be done with one suit pattern and 20 measurements is enoormous and may be why getting the fit right for a full suit is complex and error prone.
