Turn a 3D model or a photo into something to build by hand - slice a mesh into 1:1 contour templates on A3 pages (for bending wire armatures, cutting ribs, stacking layers), or turn a reference image into a depth map and a printable relief with a flat back (masks, mould formers). Use when a model has to become paper templates, wire, card or papier-mache, or when a picture should become a relief.
