I was inspired by this image (top) to see if I could generate a buildable structure in NE.

All the plank elements are indeed straight (ie the bow from flow to surface has been removed).
However it is not quite there yet, because the plank thickness varies. They will need to be uniform thickness to make structure fabrication viable. Anyway it is a start.
