When building our laminates a useful feature would be to add a box in the laminate form showing the % 0, %45 and %90 plies as the user builds a laminate. Most engineers should be aware of these design parameters when building laminates.
Also, a hover button could show a help box explaining how Hypersizer calculates the percentage of plies. A 0 deg PW fabric is really 50% 0 deg plies and 50% 90 deg plies.
