My question is, the back has bends in two planes, how do you make
the form?
Bending in one plane is a snap, two 90 degrees to each other would
not be
that hard either. However, two at once, when they are ofset about
30-40
degrees is a bit more than I am familiar with.

Known as a developed surface, find an old time Drafting text or as an
alternate, find a text that shows how to layout developed surfaces
used in the sheet metal industry.

Have fun.
