pub fn cutting_sheet(sheet: &Sheet) -> GeopResult<Sheet>Expand description
The flat pattern of sheet on paper, one model unit a unit, its
lower left corner at the origin, seen from its B side — the first
flat’s sheet coordinates: every curve of the unfolded sheet’s boundary
on the CUT layer, each bend’s line on the BEND layer, and beside it
UP 90° R0.1 — UP for a bend towards the viewer.
