Glossary

Every papercraft term on your template, explained.

What the lines, tabs and numbers on a printed sheet actually mean.

Unfolding
Flattening the surface of a 3D model into flat pieces that can be printed, cut and folded back into the original shape.
Net
The flat pattern a 3D shape unfolds into. A cube's net is six connected squares.
Piece
One connected group of panels on a sheet, cut out as a single shape.
Panel
A single flat face on a piece. Coplanar triangles are merged into one panel so there is less to cut.
Seam
An edge where the surface is cut apart so it can lie flat. Seams are placed on sharp edges so they hide in the finished build.
Mountain fold
A fold where the paper bends away from you, forming a ridge. Shown as a dashed line.
Valley fold
A fold where the paper bends towards you, forming a groove. Shown as a dash-dot line.
Cut line
A solid line. Cut these, and leave every dashed and dotted line intact.
Glue tab
A small flap added along a seam that you fold under and glue to join two pieces.
Numbered join
Matching numbers printed either side of a seam so you know which tab meets which edge.
Sub-assembly
A labeled section (A, B, C) of a model too large for one sheet, built separately then joined.
Sheet packing
Arranging pieces on printable pages so they fit inside the margins and waste as little paper as possible.
True scale
Printing at 100% so the finished model matches the real-world size you set. Every sheet prints a ruler so you can confirm it.
Manifold mesh
A watertight model where every edge joins exactly two faces. Manifold meshes unfold most predictably.
Normal
The direction a face points. Flipped normals make a model look inside out and confuse the unfolder.
Decimation
Reducing the number of triangles in a model. Essential for dense sculpts, because each triangle can become a piece to cut.
Low poly
A model built from relatively few, larger flat faces. The easiest kind of model to build in paper.
Overlap
Two pieces occupying the same space on a sheet. The studio detects overlaps and highlights them so you can move or re-cut a piece.
DXF
A CAD exchange format, exported with separate layers for cut, mountain, valley and tab geometry.
Card stock
Heavier paper, typically 160 to 250 gsm, used for models that need to hold their shape.
